The migration characteristics of multinuclides in a sandy soil layer were examined with an aerated soil layer mode apparatus under acidic, neutral and alkaline inflow conditions. The effluent ratios of each radionuclide were small under acidic and neutral...

It was shown that an office scanner can be used for the acquisition of digital images of soil samples and their analysis using the RGB color system. The content and optical density of the humic acids were the main factors determining the color intensity of sandy soils. With all the other factors being constant, the ...

Fly ash (FA) produced from subbituminous coal combustion can potentially serve as a lime material for crop production in acidic soils in areas. A five-year study was conducted to determine if FA can be used as a liming material in an acid sandy soil under corn and soybean grain production. ...

This study was attempted to evaluate the transformation of aluminum (Al) in an acidic sandy soil amended with composts (yard waste, yard + municipal waste, GreenEdge®, and synthetic humic acid), based on soil Al fractionation by single and sequential extraction. The compost amendment ...
is well known to be a major retention mechanism for N2H5 + on humic acids under acid conditions. Acidic+ and H+ cations applied in acidic solutions to columns of Ca2+ /H+ - saturated sandy soil during steadySoil and Water ...

Acid coal mine water was applied to a Linden sandy loam soil at various levels. The soil data indicated that the main reactions between the applied water and the soil occurred in the upper part of the soil profile. The cation exchange capacity of the ...
Sorption and migration experiments were performed by both batch and column methods, to study influence of humic acid complexing on the mobility of (sup 60)Co, (sup 85)Sr and (sup 137)Cs in a coastal sandy soil. The study focuses on a correlation between m...
-cup soil-water sam- plers (model 1900, Soilmoisture Equipment Corp., Santa Bar- bara, CA)1 were installed, including fine sandy loam (interpreted as till or Table 1.

The partitioning of uranium in an aquifer down gradient of two large mixed waste sites was examined with respect to the solution and soil chemistry (e.g., pH redox potential and contaminant concentration) and aqueous-phase chemical speciation. This involv...
