Baumhardt, R.L.; Wendt, C.W.; Keeling, J.W. Madison, Wis. : The Society; 1992 Jul. Soil Science Society of America journal v. 56 (4): p. 1286-1291; 1992 Jul. Includes references. Language: English Descriptors: Texas; Clay loam soils; Infiltration; Chiselling; Dikes; Furrows; Ponding; Rain; Impact; Kinetic energy; Surface layers; Crusts; Hydraulic conductivity; Water conservation Abstract: Chisel tillage and furrow dikes (small earthen dams constructed in the furrow) are commonly used to increase infiltration and soil water storage in semiarid regions. Data quantifying the combined influences of these practices are limited. Our objective was to determine the effects of chisel tillage, furrow dikes (with and without ponding), and drop impact or surface crusts on infiltration. Infiltration rate (IR) and cumulative infiltration (CI) into an Olton day loam (fine, mixed, thermic Aridic Paleustoll) were measured by applying water at 65 and 80 mm h-1 for 1 h using a rotating- disk-type rainfall simulator. Furrow dikes increased infiltration under both ponded and nonponded conditions. Cumulative infiltration was higher when raindrop impact energy was dissipated and, to some extent, when crusts were removed. Infiltration rate at the end of water application was lower with raindrop impact than when raindrop impact was eliminated; however, there were no differences in the final IR between the initially crusted and uncrusted soils. There were no differences in infiltration between chisel-disk and disk tillage measured during the mid growing season. Furrow dikes not only detain water on the surface to provide more time for infiltration, but also increase infiltration through increased hydraulic head and additional tillage performed during dike installation or by moving loose soil from the furrow into the dikes. Our data do not support using the same hydraulic- conductivity value for both diked and undiked field conditions, which may cause underestimation of conservation in furrow-diked fields. 12 NAL Call.

Language: English Descriptors: Tillage practices; Soil erosion; Soil conservation; Water pollution; Economic impact; Conservation practices; Yields; Trends Abstract: Extract: Cropland in minimum tillage rose from 15.8 percent of all cropland in 1973 to 29.1 percent in 1981. The share for no-till rose from 2.0 to 2.9 percent during the same period. These conservation tillage systems--minimum tillage and no-till--can also reduce soil loss up to 99 percent over conventional tillage. This report looks at trends in the use of various tillage systems and compares their economic impacts and effects on soil and water conservation, crop yields, and pesticide and energy use, using selected results from studies of tillage systems. 13 NAL Call.

Applied engineering in agriculture v. 7 (2): p. 209-215; 1991 Mar. Includes references. Language: English Descriptors: Water quality; Drainage; Tile drainage; Temperate zones; Crop management; Discharge; Experimental design Abstract: Experimental designs of 14 subsurface drainage- water quality studies conducted over the past 18 years are reviewed. To more accurately determine mass contaminant flux and processes, more intense monitoring of drain discharge rate and drainage water quality is needed than in most past studies. A recently installed field scale system of subsurface drainage-water quality plots and associated equipment, capable of intense, year round monitoring, is described and preliminary data showing performance of the system is presented. The material presented should be of interest to those planning and designing drainage-water quality studies, or refitting existing drainage installation for water quality investigations. 18 NAL Call.

Bethesda, Md. : Society of American Foresters; 1992 Feb. Southern journal of applied forestry v. 16 (1): p. 13-20; 1992 Feb. Includes references. Language: English Descriptors: Alabama; Florida; Georgia; Harvesting; Logging; Water quality; Protection; Resource conservation; Economic analysis; Costs Abstract: Data on harvest volumes, topography, and other site and area characteristics were obtained from 22 timber harvests in Alabama, Florida, and Georgia. An economic analysis was then used to estimate the marginal costs of implementing each state's recommended Best Management Practices (BMPs), as well as a set of enhanced BMPs an these sites. Considering all of the areas combined, the costs of using the recommended BMPs averaged 2.9% of gross timber sale revenue, $2.34 per thousand board feet (mbf) of timber harvested, or $12.45/ac. The cost of implementing the enhanced BMPs averaged 5.1% of gross stumpage value, $4.13/mbf, or $21.94/ac. Seed, fertilizer, and mulch, broad based dips, and water bars were the most expensive practices on a total cost basis. Culvert installation, streamside management zones, and road relocation costs were less expensive for most tracts. 20 NAL Call.

Language: English Descriptors: Zea mays; Poly(vinyl alcohol); Phosphorus; Runoff; Losses from soil systems; Surface treatment; Mineral content; Nutrient content; Loam soils; Crop yield; Plant height; Erosion; Nutrient availability Abstract: Phosphorus loading in surface water bodies due to runoff from cropland is a major concern with respect to water quality. Losses of water, soil, and different forms of P, from five runoff plots treated with polyvinyl alcohol (PVA), were compared to losses from five untreated plots. The plots were on a loam soil with 6.5 to 9.5% slopes. The effect of a single application of PVA was observed over 2 yr under natural rainfall. During the first year after application of PVA, runoff and soil losses were reduced by 56 and 80% respectively. Extractable P, total P, and dissolved molybdate- reactive P (DMRP) losses were reduced by 79, 75, and 64%, respectively. Corn (Zea mays L.) grain yield on the treated plots was 12% higher than on the control plots. All the above differences were statistically significant. During the second year, in which no tillage occurred and no PVA was applied, total P and DMRP losses were reduced by 42 and 40%, respectively, by the PVA treatment of the previous year. Although runoff and soil loss were lower for the treated plots, these differences were not significant at P = 0.05 (P values were 0.11 and 0.10, respectively). 34 NAL Call.

Language: English Descriptors: Maryland; Atrazine; Herbicide residues; Spatial variation; Spatial distribution; Tillage; No-tillage; Rhizosphere; Rain; Soil depth; Maize soils; Coastal plain soils Abstract: High variability of atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5 triazine) residues in soil and shallow groundwater have been reported under various agricultural management systems. This 2-yr study was conducted to evaluate atrazine residue levels in soil as influenced by no-till (NT) vs. conventional-till (CT) under natural rainfall conditions. Atrazine was applied annually (at 1.34 kg/ha), 1 d after corn (Zea mays L.) planting, to two NT and two CT plots. Atrazine residues within the 0- to 10-cm soil depth of CT plots were higher than in the NT plots, regardless of the difference in the rainfall patterns. Higher (ca. 61%) mean atrazine residues in the CT plots over NT plots in 1988 was most likely related to the rainfall that began 12 h after application. In contrast, in 1987, it rained 3 to 4 d after application and the residues in the CT were only 31% higher than in NT. These results indicate that even a subtle difference in rainfall distribution (temporal) can result in marked spatial variability in the distribution of atrazine. 38 NAL Call.

Language: English Descriptors: Louisiana; Flooded rice; Fields; Water quality; Mineral content; Nutrient content; Pesticide residues; Surface water; Water management; Cultivation; Flood irrigation; Sediment Abstract: Water samples collected in the Mermentau River Basin over several years at Louisiana Department of Environmental Quality monitoring sites contained high levels of total solids and nutrients during the spring that were highly correlated to pre- and post-plant discharges from rice fields. This study was developed to evaluate the potential of selected management practices (MP's) for reducing total solids, nutrients and pesticides from discharge water in order to improve the surface water quality in southwest Louisiana. Five rice plots located on the Rice Research Station in Crowley, LA represented the different MP's to be evaluated. The five water seeding MP's were: a.1-no till; a.2-water cultivation with 30-day settling, a.3-dry cultivation with clear water planting; a.4-mudding-in with vegetated filter, and b-mudding-in (control). Quality of discharged water from rice fields in the Mermentau River Basin was clearly affected by the different MP's. From the first year of data, all the MPa's were better than the mudding-in (MPb). The concentrations of the total solids (kg/ha) in the discharged water (initial + final drain) for the different MP's were in the order: MPb(4860) > MPa.3(3906) > MPa.4(3412) > MPa.2(3068) > MPa.1(1807). The Mpa.3, Mpa.4 and MPb had no detectable amounts of pesticides being released. The 30-day holding period (Mpa.2), clear water planting (MPa.3) and the mudding- in with vegetated filter (MPa.4) were similar as far as TDS, TSS and TS with the no-till (MPa.1) being the least. The 30- day holding period (Mpa.2) and the no-till (MPa.1) had less nutrients, but more pesticides released. Depending on the priority of the stream problems, different MP's may be more advantageous than others. All of the selected MP's were better than the control (MPb), and therefore, should help to improve water quality. 46 NAL Call.

Language: English Descriptors: Virginia; Sludges; Nitrogen fertilizers; Phosphorus fertilizers; Application to land; No-tillage; Tillage; Nitrogen; Phosphorus; Losses from soil systems; Runoff water; Water quality; Sediment Abstract: Simulated rainfall was used on experimental field plots to compare the effect of chemical fertilizer and sludge application on sediment, nitrogen, and phosphorus in runoff from no-till and conventional tillage systems. Chemical fertilizer application under the no-till system resulted in the least amount of total N and P in surface runoff. However, sludge application under the no-till system resulted in the least amount of NO3-N and sediment in surface runoff. The worst water quality scenarios were observed when either sludge or chemical fertilizer were surface-applied under a conventional tillage system. Nitrogen losses from the conventional tillage system were minimized when sludge was incorporated into the soil. However, phosphorus and sediment yield from such a system were significantly higher when compared to phosphorus and sediment yield from the no-till system. The results from this study indicate that the use of sludge on agricultural land under a no-till system can be a viable alternative to chemical fertilizer for nitrogen and phosphorus control in runoff. A more cautious approach is recommended when the sludge is incorporated into the soil in a conventional tillage system because of potential for high sediment and phosphorus yield in surface runoff. 55 NAL Call.

Language: English Descriptors: Texas; Panicum coloratum; Cynodon dactylon; Gramineae; Selenium; Ion uptake; Mineral content; Uranium; Mine spoil; Shoots; Dry matter accumulation; Cover crops Abstract: High soil selenium (Se) levels have been found in association with uranium deposits in Texas. A concern that high Se concentrations may be found in forages grown on reclaimed mine lands prompted this investigation. A native soil sampled near the mining area, and overburden materials sampled from two Se enriched uranium mine soil sites were compared in a plant growth study in the greenhouse. Shoot yields and shoot Se concentration in each of ten grasses common to the region were determined from plants harvested three weeks after germination and from shoot regrowth harvested four weeks after the first harvest. Shoot weights were reduced for 5 of the 10 species growing in soils with medium and high Se status. Total shoot weights of Cynodon dactylon and Panicum coloratum from two harvests were consistently highest in all soil materials and are highly recommended for use as a stabilizing cover crop for lands disturbed from uranium mining. Generally, no correlation was observed between shoot weight and plant Se concentration or uptake in the 10 species. However, plant tissue Se concentrations in all species for at least one of the two harvest dates were above the 5 mg kg-1 concentration considered potentially harmful to grazing livestock. Therefore, none of these species would be a suitable forage for livestock grazing on reclaimed Se-enriched uranium mining overburden. 85 NAL Call.

Language: English Descriptors: Wisconsin; Stream flow; Catchment hydrology; Conservation tillage; Agricultural land; Land management; Land use; Soil conservation; Erosion; Runoff; Floods; Precipitation; Seasonal variation Abstract: Since the mid-1930s a variety of soil conservation practices have been applied to agricultural lands throughout the United States. While intended to reduce soil erosion, if effective, these practices should alter the hydrology of streams which drain the treated lands. This hypothesis was explored for the East Branch of the Pecatonica River, a gaged 221 square mile agricultural catchment in southwestern Wisconsin. On the basis of the analysis of peak and daily flow data there has been a decrease in flood peaks and in winter/spring flood volumes and an increase in hydrologic rise times and in the contribution of winter/spring snowmelt events to base flow. These changes do not appear to be due to climatic variations, reservoir construction, or major land use changes. Instead, they appear to have resulted from the adoption of various soil conservation practices, particularly those involving the treatment of gullies and the adoption of conservation tillage. 90 NAL Call.

The 1.28-ha field site was divided into four plots, two each devoted to no-till and conventional tillage management. Pesticide transport was evaluated by monitoring the rate of change in concentrations of pesticides in a shallow perched water table, located approximately 1 m below the soil surface. Pesticides monitored included atrazine, alachlor, cyanazine and carbofuran. All three herbicides were applied as a single broadcast spray: granular insecticide carbofuran was band- injected at planting. 97 NAL Call.

Madison, Wis. : The Society; 1990 Nov. Soil Science Society of America journal v. 54 (6): p. 1530-1536. ill; 1990 Nov. Includes references. Language: English Descriptors: Zea mays; No-tillage; Macropores; Macropore flow; Atrazine; Strontium; Bromides; Movement in soil; Groundwater pollution; Agricultural chemicals; Rain; Percolation; Leaching Abstract: Previous research has established that macropores can rapidly transmit water through soil. This observation has raised concern that macropores may also promote rapid movement of agricultural chemicals to groundwater. This is a particular concern for no-till fields where lack of disruption by tillage can lead to the development of extensive macropore systems. In order to investigate the effect of initial rainfall on chemical transport, strontium bromide hexahydrate (SrBr2.6H2O) and atrazine (2-chloro-4-ethylamino-6-isopropylamino-s- triazine) were surface-applied to six 30 by 30 by 30 cm blocks of undisturbed soil obtained from a 25-yr-old, no-till corn (Zea mays L.) field with evidence of well-defined macropores attributable to earthworm activity. Half of the blocks then received a 1-h 5-mm simulated rain, which did not produce percolate. Two days later, the blocks received a 0.5-h 30-mm simulated rain, followed by another 0.5-h 30-mm rain 1 wk later. The remaining blocks received only the two 30-mm events. An average of 12% of the applied water passed through all the blocks during and shortly after the first 30-mm rain. Bromide, Sr, and atrazine losses in this percolate were 7, 10, and 2 times less, respectively, from blocks that received the 5-mm rain than from blocks not receiving this initial, light rain. The second 30-mm rain on the blocks not receiving the initial 5 mm produced 1.6 X more percolate than the first 30- mm rain. Yet, transport and flow-weighted average concentrations of Br, Sr, and atrazine were all reduced. These results indicated that the first storm after application can move solutes into the soil matrix, thereby reducing the potential for transport in macropores during subsequent rainfall events. 102 NAL Call.

Language: English Descriptors: Plowing; No-tillage; Nitrate nitrogen; Leaching; Ammonium nitrate; Atrazine; Carbofuran; Diazinon; Metolachlor; Movement; Groundwater pollution; Zea mays Abstract: The fate of agrochemicals is often greatly affected by the surface-soil conditions in the field. This study was conducted to characterize the impact of two contrasting tillage systems on the movement of agrochemicals in soil. The two tillage systems were plow-tillage (PT) and no-tillage (NT) for corn (Zea mays L.) production. The study included incubation and leaching of undisturbed soil columns and disturbed soil samples from 16-yr plots subject to the two tillage regimes. The agrochemicals used in the study were NH4NO3, atrazine (2-chloro-4-ethylamino-6- isopropylamino-1,3,5-triazine-2,4 diamine), carbofuran (2,3- dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate), diazinon (0,0-diethyl-O-(6-methyl- 2(1-methethyl)-4-pyramidinyl phosphor- othioate), and metolachlor (2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2- metoxy-1-methylethyl) acetamide). The results of this study show greater ponded flow movement of all agrochemicals in soils under PT vs. NT conditions. Strong evidence was found for preferential flow through the soil, with the chemicals by- passing much of the soil-matrix under recently plowed soils as well as NT soils. Nitrate leaching was significantly greater under PT than NT, apparently due to greater mineralizing activity of the PT soil compared with the NT soil. The pesticide movement also tended to be greater under PT than NT. Caution should be exercised in generalizing to field conditions, but these data suggest that there can be greater leaching losses of surface-applied agrochemicals to groundwater under PT than under NT. 115 NAL Call.

A wide range of field scenarios was modeled as part of the economic evaluation of the RCWP (Rural Clean Water Program) project. Best management practices (BMOs) reduced surface losses of nutrients. Reducing the amount of nitrogen applied to the field was the only effective method for reducing percolate losses of nitrates. Stored manure provides more plant-available nitrogen than does daily-spread manure. 116 NAL Call.

Language: English Descriptors: Unsaturated flow; Transport processes; Solutes; Drained conditions; Soil water balance; Water table; Water quality; Prediction; Simulation; Mathematical models; Algorithms Abstract: Long-term assessment of solute transport in the unsaturated zone is an important consideration for irrigation management, pesticide management, and subsurface contaminant restoration analysis and design. Mathematical models are often used to perform such analyses. Modeling fluid flow and solute transport in the unsaturated zone typically requires solution of the nonlinear Richards equation and an advective-dispersive equation for contaminant transport as a function of time. Such solutions are possible but computationally expensive. A simplified water balance approach to solve fluid flow in shallow, drained unsaturated zones has been developed and refined over the last 15 years. The objectives of this study were to use results from a water balance model to obtain solutions for solute transport in drained, shallow water table soils, and to compare the results with solutions based upon Richards' equation. Transient soil water flux rates computed with a water balance model were used as input to a Petrov- Galerkin advective-dispersive transport model to simulate solute transport in unsaturated soils. The transport model was checked for consistency by comparison with an analytical solution. Sample simulations showed good agreement between a Richards' equation-based transport model and a water balance- based transport model. Simulations were performed to show predicted trends in water quality over 1-year periods. 120 NAL Call.

A probabilistic alternative is developed. The focus is on methods for evaluating whole-farm pollution control plans rather than individual practices. As a consequence, the analysis is presented in a chance-constrained activity analysis framework because activity analysis procedures are a practical and well developed device for screening farm plans. Reliability of control is shown to be as important as reduction targets in designing farm plans for pollution control. Furthermore, broad-axe prescriptions of technology in the form of Best Management Practices may perform poorly with respect to cost effectiveness. 134 NAL Call. No.: 290.9 AM32T Predicting runoff of water, sediment, and nutrients from a New Zealand grazed pasture using CREAMS. Cooper, A.B.; Smith, C.M.; Bottcher, A.B. St. Joseph, Mich. : American Society of Agricultural Engineers; 1992 Jan. Transactions of the ASAE v. 35 (1): p. 105-112; 1992 Jan. Includes references. Language: English Descriptors: New Zealand; Grassland management; Grazing effects; Hydraulic conductivity; Losses from soil systems; Prediction; Runoff; Water quality; Computers; Simulation models Abstract: The ability of the CREAMS model to predict loadings of runoff, sediment and nutrients from a New Zealand grazed pasture was evaluated. Before use, CREAMS was adapted to better represent N and P cycling in grazed pastures and the seasonal variation in hydraulic conductivity observed at the site. There was a moderately strong relationship (r2 = 0.81) between daily surface runoff volumes predicted by this modified model and volumes measured at the site for 62 events over a three and one half year period. Although the ability of the model to predict daily losses of sediment and nutrients was considerably less (r2 < 0.45), the model was always an unbiased predictor. This unbiased predictive ability provides good estimates of losses over longer time scales (e.g., seasonal) which is often sufficient when evaluating the impacts of land use practices on water quality. The adapted CREAMS model successfully simulated measured reductions in edge-of-field losses of sediment and nutrient upon installation of a vegetated filter strip. We conclude that although CREAMS has limitations in representing the dynamics of grazed pastures, it shows potential as a water quality management tool in pastoral watersheds. 135 NAL Call.

St. Joseph, Mich. : American Society of Agricultural Engineers; 1991 Jul. Transactions of the ASAE v. 34 (4): p. 1699-1705; 1991 Jul. Includes references. Language: English Descriptors: Maryland; Atrazine; Cyanazine; Field tests; Groundwater; Movement in soil; Silt loam soils; Water pollution Abstract: The relative importance of preferential pesticide transport in agricultural soils was determined in a two-phase study conducted on a silt loam soil in Maryland. The first phase (1984) consisted of evaluating persistence and mobility of atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine] and cyanazine [2-chloro-4-(l-cyano-l-methylethylarnino)-6- ethylamino-s-triazine] under no-tillage corn management. The second phase (1986) dealt with persistence and mobility of the same herbicides on fallow tilled soil subjected to frequent, large water inputs. Although preferential flow was observed under both treatments and water regimes, the no-till system had the most rapid movement of herbicide relative to water inputs. Additionally, all treatments indicated that the greatest potential movement of surface-applied pesticide occurred with the first water input subsequent to application. Once the pesticide has been preferentially transported, it appears to diffuse into the soil matrix, where it is no longer subject to significant preferential movement. Based on field data and calculated mass balance, persistence of atrazine and cyanazine was unaffected by tillage practice and water regime. 136 NAL Call.

Language: English Descriptors: Tillage; No-tillage; Metolachlor; Herbicide residues; Soil pollution; Rain; Runoff water Abstract: Monolithic soil cores were used to evaluate the impact of tillage and point-of-chemical placement on off-site movement of metolachlor. Nine 254-mm diameter soil cores were removed from an agriculturally productive field site and positioned under a rainfall simulator. Provisions were made for collecting surface runoff and deep seepage from the cores. A one-time application of metolachlor at a rate of 2.2 kg active ingredient per ha was made to three bare, tilled surfaces, three untilled surfaces beneath a covering of wheat straw, and three untilled surfaces over-the-top of a covering of wheat straw. The nine cores were subjected to simulated rainfall events of 26.5 mm per hr intensity at 4, 48, 168, 504, 1008, and 2016 hours after application of metolachlor. A small quantity of metolachlor exited the cores in both runoff and in deep seepage water. There were no significant differences in concentrations of metolachlor in deep seepage among cores with the three different surface treatments. There was, however, significantly more metolachlor in runoff from cores where the chemical was applied over-the-top of wheat straw. Results, thus, indicate that a contribution to improved water quality may be made by developing under-residue herbicide application practices. 139 NAL Call.

Language: English Descriptors: Texas; No-tillage; Tillage; Soil management; Clay soils; Triticum aestivum; Zea mays; Sorghum bicolor; Sediment; Nutrients; Losses from soil; Runoff water; Water pollution; Nitrogen; Phosphorus; Agricultural land; Watersheds Abstract: Agricultural source pollution of water resources has been a source of concern in recent years. Research is needed to define mechanisms of chemical and sediment loss in runoff from agricultural land, and to develop management practices that minimize transport of these pollutants. This study was designed to compare the effect of no-till (NT) and conventional chisel-till (CT) soil management on runoff water volumes, sediment loss, and N and P loss from small watersheds on a clay soil. Three NT and three CT watersheds located on Houston Black clay vertisol soil (fine, montmorillonitic, thermic, Udic Pellusterts) in east central Texas were used for the study. Wheat (Triticum aestivum L.), corn (Zea mays L.) and sorghum [Sorghum bicolor (L.) Moench] were grown rotationally on the watersheds from 1984 to 1989. Runoff amounts, sediment loss, and N and P losses were measured for each rainfall event that produced runoff. Runoff volume was not changed by tillage system and sediment loss and N and P losses in runoff were less, on average, from NT than from CT. Runoff averaged 1.3 ML ha-1 annually for both CT and NT. Average annual quantities for sediment and nutrient losses were: 160 kg ha-1 and 1575 kg ha-1 for sediment, 3.8 kg ha-1 and 8.1 kg ha-1 for N, and 0.8 kg ha-1 and 1.5 kg ha-1 for P for NT and CT, respectively. These results indicate that the loss of sediment and nutrients from agricultural lands could be minimized by using NT on clay soils. 140 NAL Call.

Manure, incorporated by cultivating, rototilling or plowing, was applied annually from 1973 to 1983 at 30, 60, and 90 Mg ha-1 (wet wt.) and 60, 120, and 180 Mg ha-1, respectively, to nonirrigated and irrigated dark brown Chernozemic (Typic Haploborolls) clay loam soil. On both the nonirrigated and irrigated soil, the effects from manure, applied annually at greater than recommended rates for 11 yr, were minimal on Cu and NH4 content and substantial on other parameters determined. There were no significant effects due to tillage methods on these soil parameters. The effects on these soil parameters extended to greater depths under irrigation than under nonirrigation. Most of the applied NH4 was nitrified, volatilized, or fixed. The accumulation of organic matter, total N, NO3, total P, available P, soluble Na, Ca+Mg, Cl, SO4, HCO3, and Zn in the soil increased with increasing rates of manure applied. The electrical conductivity and sodium adsorption ratio of the soil increased and the soil pH in the surface 60 cm of nonirrigated and 90 cm of irrigated decreased with increased manure rates. The total NO3 accumulation in the 150-cm soil depth was near 1 Mg ha-1, even at recommended rates, and was high enough to potentially cause soil and water pollution. The available P accumulated mostly in the surface soil and might be sufficient to interfere with the nutrient balance of some crops. Long-term annual application of cattle manure to southern Alberta soils at maximum recommended rates [30 mg ha-1 and 60 Mg ha-1 (wet wt.) for nonirrigated and irrigated land, respectively] is not advisable. 142 NAL Call.

Language: English Descriptors: Erosion; Surface water; Water management; Removal; Water conservation; Crop production; Sedimentation; Conservation tillage; Cropping systems Abstract: Management of surface water has four broad objectives: (1) Appropriate removal of excess water during wet periods, (2) Water conservation for crop use, (3) On-site erosion control to protect long-term soil productivity and reduce short term damages, and (4) Off-site damage prevention from sedimentation and water pollution. The various techniques of water management vary in effectiveness for the four objectives given. However, for production of crops on erodible land the importance of water conservation to enhance yield and potential profits must be emphasized. The benefits of water management for on-site erosion control are well established. Economic studies, however, conclude that structural approaches to control on-site erosion are seldom profitable in terms of protecting soil productivity. The use of a tillage and cropping system designed for erosion protection is economically more attractive than structures, especially if the cropping system does not greatly reduce the total value of farm products sold. In contrast to the on site losses annual costs of off-site damages from cropland erosion and runoff are probably 10 to 55 times as great. Grain crop production on highly erodible land continues to be difficult and risky. Whether farmers can achieve this profitably, and with conservation compliance as defined by the 1985 Food Security Act, will greatly depend upon the alternative types of land available and the extent of conservation treatment required. 147 NAL Call.

Language: English Descriptors: Tennessee; Vegetation types; Watersheds; Erosion control; Soil conservation; Vegetation; Cost effectiveness analysis; Water composition and quality Abstract: Extract: The public cost of reducing erosion in a west Tennessee watershed pilot program was 34 percent lower than the national average. The difference was attributed to the pilot program's emphasis on targeting specific erosion problems and to the establishment of permanent vegetative cover on highly eroding land. Even greater use of permanent vegetative cover, no-till cropping practices, and less reliance on cover improvement and terraces could reduce erosion in the area by an additional 32 percent with the same level of funds. A variable cost-sharing approach to erosion control may yield even bigger dividends in a targeting program. 148 NAL Call. No.: TD227.O5A37 Technology Evaluation and Development sub-program of SWEEP.

Language: English Descriptors: Kentucky; Zea mays; Tillage; Chiselling; No- tillage; Runoff; Sediment; Runoff water; Ammonium nitrate; Triple superphosphate; Potassium fertilizers; Triazine herbicides; Crop yield; Silt loam soils Abstract: As the role of nonpoint-source contamination of surface waters becomes more evident, increasingly more attention is focused on the effects of agricultural practices on soil erosion and water quality. Tillage systems are known to affect the amount of water moving over the surface and through the soil. This study compared the contributions of three tillage systems used in corn (Zea mays L.) production with (i) sediment losses and surface runoff and (ii) the potential for nonpoint-source surface water pollution from N and P fertilizers and triazine herbicides. Tillage treatments were no-tillage, chisel-plow tillage, and conventional tillage (moldboard plow plus secondary tillage). The study site was on a Maury silt loam (Typic Paleudalfs). Over the 4-yr period, conventional tillage runoff volume was 576.7 kL ha-1, chisel- plow 205.7 kL ha-1, and no-tillage 239.9 kL ha-1. Total soil loss from conventional tillage was 19.79 Mg ha-1, chisel plow 0.71 Mg ha-1, and no-tillage 0.55 Mg ha-1. Amounts of NO3(-), soluble P, and atrazine leaving the plots in surface runoff were greatest from conventional tillage and about equal from chisel-plow and no-tillage. The magnitudes of the losses in surface runoff water were small for all chemicals measured. 156 NAL Call. No.: 290.9 AM32T Transport comparison of technical grade and starch- encapsulated atrazine.

Language: English Descriptors: Atrazine; Encapsulation; Groundwater; Leaching; Movement in soil; Starch; Trickle irrigation; Water pollution Abstract: The feasibility of using starch-encapsulated atrazine to minimize convective transport under conditions favoring preferential flow was evaluated. Forty small, undisturbed, soil columns (45 cm2 X 3 cm) were removed from an established no-tillage management site and randomly grouped into one of five atrazine treatments: 1) technical grade; 2) borate process, starch-encapsulated; 3) jet-cooked, pearl starch-encapsulated; 4) jet-cooked, waxy starch-encapsulated; and 5) untreated control. Columns were drip-irrigated at the rate of 2.5 cm every three days. Highest atrazine levels, 1.30 mg L-1, were observed in the effluent from columns receiving technical-grade atrazine after the first irrigation (2.3 pore volumes), even though piston flow theory indicated that atrazine should not have appeared before 21.9 pore volumes. Computer simulations using the general convection-dispersion equation with first-order dissipation and linear adsorption also significantly underpredicted atrazine mobility. All encapsulated formulations, relative to technical-grade, revealed significantly lower initial atrazine levels in the effluent. Cumulative effluent concentrations indicate that after 16.1 pore volumes, 35, 10, 3, and < 1% of the available atrazine had been leached from the technical-grade, borate, pearl, and waxy starch formulations, respectively. 157 NAL Call.

Evaluation of the impact of agricultural management on BAP in runoff will aid assessment of the resultant biological productivity of receiving water bodies. Soluble P, PP, and bioavailable PP (BPP) (estimated by NaOH extraction) were determined over a 5-yr period in runoff from 20 unfertilized and fertilized, grassed, and cropped watersheds in the Southern Plains. Soluble P, BPP, and BAP loss in runoff was reduced by practices minimizing erosion and runoff, with respective mean annual amounts ranging from 237 to 122, 1559 to 54, and 1796 to 176 g P ha-1 yr-1 (for peanut- sorghum [Arachis hypogaea L.-Sorghum bicolor (L.) Moench] and native grass watersheds, respectively). However, as vegetative cover improved, BAP (SP plus BPP) comprised a larger portion of total P (TP) loss (29% for peanut-sorghum and 88% for native grass). This results from an increasing contribution to BAP of SP (13% for peanut-sorghum and 69% for native grass watersheds) and BPP to PP (26% for peanut-sorghum and 69% for native grass watersheds). Clearly, P bioavailability is a dynamic function of physiochemical processes controlling erosion, particle size enrichment, P desorption-dissolution reactions, and plant residue breakdown, in addition to soil and fertilizer P management. Hence, the change in trophic state of a water body may not be adequately reflected by TP inputs only. To more reliably evaluate the biological response of a water body to agricultural P inputs, particularly from conservation tillage practices, it may be necessary to determine BAP in runoff. 158 NAL Call.

Language: English Descriptors: Oklahoma; Texas; Triticum aestivum; Nitrogen fertilizers; Phosphorus fertilizers; Losses from soil systems; Runoff; Sediment; Tillage; Environmental impact; Groundwater; Surface water; Water quality; Watersheds Abstract: Water quality information regarding wheat culture in the Southern Plains is sparse. The objective of this study is to determine the extent to which the area's surface and ground-water quality is influenced by different wheat cultural practices. Concentrations and amounts of sediment, N and P in surface runoff water were determined for conventional till (CT), reduced till (RT), and no till (NT) wheat (Triticum aestivum L.) watersheds in the High Plain, Reddish Prairie, and Rolling Red Plain land resource areas of Oklahoma and Texas. During the 4 to 6 yr study periods, RT and NT practices were superior to CT for reducing sediment and associated particulate nutrient discharge. Mean annual discharge ranged from 230 to 15 900 kg ha-1 for sediment, 1 to 27 kg ha-1 for total N, and 0.1 to 6 kg ha-1 for total P. Irrespective of tillage practice, annual soluble nutrient losses in surface runoff water tended to be small, often < 1 kg ha-1 N or P. Successful prediction of soluble P, particulate P, and particulate N losses was achieved using appropriate kinetic desorption and enrichment ratio procedures. Soluble N in runoff posed no particular water quality problem, but recommended P levels were exceeded, even from baseline, unfertilized grassland watersheds. With regard to groundwater quality, elevated levels of NO3- (e.g., 34 mg N L-1 maximum) were observed on one Reddish Prairie NT watershed. 164 NAL Call.

Language: English Descriptors: Water management; Water quality; Water table; Drainage; Hydrology; Simulation models; Subsurface irrigation Abstract: Impacts of water table management (WTM) practices on water quality were modeled using a linked version of CREAMS and DRAINMOD (Parsons and Skaggs, 1988). The CREAMS denitrification component and the linked DRAINMOD-CREAMS model were modified to simulate daily hydrology (runoff, infiltration, evaporation, and soil moisture content), erosion, and nutrient processes for different WTM conditions. Measured data from Baton Rouge, Louisiana, were used to validate the linked model, and then controlled drainage- subirrigation (CD-SI) was simulated to investigate the effects of different WTM systems on runoff, erosion, and nitrogen losses. Results of the study indicated that the linked models performed better than the original CREAMS model in predicting runoff, infiltration, soil moisture content, and erosion, and that the modified linked model performed better than both CREAMS and the original linked model in predicting nitrogen losses from the study site. Results also showed that the CD-SI system simulated by the modified DRAINMOD-CREAMS model predicted increased denitrification and lowered nitrate leaching, unlike the original version. This study concluded that the CD-SI system may be used as a BMP to reduce nitrogen leaching to shallow groundwater systems for areas with high water table conditions.

They are 1) individuals; 2) libraries, other information centers, and commercial organizations; and 3) foreign libraries, information centers, and commercial organizations. Available services for each user category are given below. For information on electronic access for interlibrary loan requests, the "Interlibrary Loan" file. 1) DOCUMENT DELIVERY SERVICES TO INDIVIDUALS The National Agricultural Library (NAL) supplies agricultural materials not found elsewhere to other libraries. Filling requests for materials readily available from other sources diverts NAL's resources and diminishes its ability to serve as a national source for agricultural and agriculturally related materials. Therefore, NAL is viewed as a library of last resort. SUBMIT REQUESTS FIRST TO LOCAL OR STATE LIBRARY SOURCES PRIOR TO SENDING TO NAL. In the United States, possible sources are public libraries, land-grant university or other large research libraries within a state. In other countries submit requests through major university, national, or provincial institutions. If the needed publications are not available from these sources, submit requests to NAL with a statement indicating their non-availability. Submit one request per page following the instructions for libraries below. NAL'S DOCUMENT DELIVERY SERVICE INFORMATION FOR THE LIBRARY The following information is provided to assist your librarian in obtaining the required materials. LOAN SERVICE -- Materials in NAL's collection are loaned only to other U.S. libraries. Requests for loans are made through local public, academic, or special libraries. The following materials are not available for loan: serials (except USDA serials); rare, reference, and reserve books; microforms; and proceedings of conferences or symposia. Photocopy or microform of non-circulating publications may be purchased as described below. DOCUMENT DELIVERY SERVICE -- Photocopies of articles are available for a fee. Make requests through local public, academic, or special libraries. The library will submit a separate interlibrary loan form for each article or item requested. If the citation is from an NAL database (CAIN/AGRICOLA, "Bibliography of Agriculture," or the NAL Catalog) and the call number is given, put that call number in the proper block on the request form. Willingness to pay charges must be indicated on the form. Include compliance with copyright law or a statement that the article is for "research purposes only" on the interlibrary loan form or letter. Requests cannot be processed without these statements. Please read copyright notice below. CHARGES: * Photocopy, hard copy of microfilm and microfiche - $5.00 for the first 10 pages or fraction copied from a single article or publication. $3.00 for each additional 10 pages or fraction. * Duplication of NAL-owned microfilm - $10.00 per reel. * Duplication of NAL-owned microfiche - $5.00 for the first fiche and $ .50 for each additional fiche per title. BILLING - Charges include postage and handling, and are subject to change. Invoices are issued quarterly by the National Technical Information Service (NTIS), 5285 Port Royal Road, Springfield, VA 22161. Establishing a deposit account with NTIS is encouraged. DO NOT SEND PREPAYMENT. Send Requests to: USDA, National Agricultural Library Document Delivery Services Branch, ILL, PhotoLab 10301 Baltimore Blvd., NAL Bldg. Beltsville, Maryland 20705-2351 Contact the Head, Document Delivery Services Branch in writing or by calling (301) 504-5755 with questions or comments about this policy. 3) DOCUMENT DELIVERY SERVICES AVAILABLE TO FOREIGN LIBRARIES, INFORMATION CENTERS AND COMMERCIAL ORGANIZATIONS. The National Agricultural Library (NAL) accepts requests from libraries and other organizations in accordance with the national and international interlibrary loan code and guidelines. In its national role, NAL supplies copies of agricultural materials not found elsewhere. Filling requests for materials readily available from other sources diverts NAL's resources and diminishes its ability to serve as a national source for agricultural and agriculturally related materials. Therefore, NAL is viewed as a library of last resort. Submit requests to major university libraries, national or provincial institutions or network sources prior to sending requests to NAL. If the needed publications are not available from these sources, submit requests to NAL with a statement indicating their non-availability. AGLINET -- Requesters in countries with an AGLINET library are encouraged to make full use of that library and its networking capabilities. As an AGLINET participant, NAL provides free document delivery service for materials published in the United States to other AGLINET participants. REQUESTS -- Submit requests on the American Library Association (ALA) or the International Federation of Library Associations and Institutions (IFLA) interlibrary loan form or via electronic mail or telefacsimile (see over for more details). Include the complete name of the person authorizing the request on each form; the standard bibliographic source which lists the title as owned by NAL; and the call number if the citation is from an NAL database(CAIN/AGRICOLA, "Bibliography of Agriculture", or the NAL catalog). DOCUMENT DELIVERY SERVICE -- Submit a separate completed interlibrary loan form for each article requested. Indicate willingness to pay charges on the form, and compliance with copyright law or include a statement that the article is for "research purposes only". Requests cannot be processed without these statements. Please read copyright notice below. CHARGES: * Photocopy, hard copy of microfilm and microfiche - $5.00 for the first 10 pages or fraction copied from a single article or publication. $3.00 for each additional 10 pages or fraction. * Duplication of NAL-owned microfilm - $10.00 per reel. * Duplication of NAL-owned microfiche - $5.00 for the first fiche and $ .50 for each additional fiche per title. BILLING - Charges include postage and handling, and are subject to change. Invoices are issued quarterly by the National Technical Information Service (NTIS), 5285 Port Royal Road, Springfield, VA 22161. Establishing deposit account with NTIS is encouraged. Annual billing is available to foreign institutions on request by contacting NAL at the address below. DO NOT SEND PREPAYMENT.

Under certain conditions specified in the law, libraries and archives are authorized to furnish a photocopy or other reproduction. One of these specific conditions is that the photocopy or reproduction is not to be "used for any purpose other than private study, scholarship, or research." If a user makes a request for, or later uses, a photocopy or reproduction for purposes in excess of "fair use," that user may be liable for copyright infringement. This institution reserves the right to refuse to accept a copying order if, in its judgement, fulfillment of the order would involve violation of copyright law. 37 C.F.R. 201.14 **************************************************************** The United States Department of Agriculture (USDA) prohibits discrimination in its programs on the basis of race, color, national origin, sex, religion, age, disability, political beliefs, and marital or familial status.
