Research Project:
IMPACT OF SOIL RESOURCE MANAGEMENT ON SOIL BIOCHEMICAL AND CHEMICAL PROCESSES
Location: National Soil Erosion Research Lab
Project Number: 3602-12220-006-00
Project Type:
Appropriated
Start Date: Mar 29, 2006
End Date: Mar 28, 2011
Objective:
Enhance carbon sequestration for improved soil quality and erosion control; Quantify the form and release of major nutrients as affected by soil redox potential; Determine the impacts of conservation tillage on fate of pesticide in soil.
Approach:
Quantify dissolved organic carbon in runoff samples from subwatersheds in the St. Joseph River; Identify enzymes as soil quality indicators; Monitor effects of changing soil redox potential on nutrient form and release; Quantify the fate of atrazine, metolachlor and glyphosate under varying temperature and crop residue; Quantify the competition between glyphosate and phosphorus and glyphosate and potassium for possible nutrient decline due to glyphosate usage.
