Area of Focus
Nutrient transformations and gaseous emissions from manure-impacted environments.
Major Project Activities:
Modern agriculture faces many challenges relating to the accumulation, handling, storage, and application of animal manure. Current research project activities include evaluating alternative feedlot runoff treatment systems, investigating the controls on gas emission hot-spots in cattle feedlots, understanding microbial nutrient transformations in shallow aquifers, and documenting odor compound emissions from cropland receiving animal manure. A variety of collaborations with university and other ARS locations enable a multi-component approach that provides additional information related to the fate of pharmaceuticals, manure pathogens, and nutrients in these projects.
