1a. Objectives (from AD-416)
To evaluate the environmental impacts (both odor and water quality) of in-house poultry litter windrow composting.
1b. Approach (from AD-416)
Runoff samples will be collected from all field sites at the USDA-ARS facility at Riesel for 2 years to compare the water quality impacts of applying fresh litter and in-house windrow composted litter.
3. Progress Report
This project, conducted in cooperation with Texas Water Resources Institute (TWRI)of Texas AgriLife Research and Extension, was designed to reduce bacteria runoff and other negative environmental impacts of poultry litter application through demonstration and evaluation of an in-house windrow composting (IWC) procedure. To date, one year of baseline data prior to litter application has been collected. Beginning in FY2012, the water quality and odor impacts of applying fresh litter (common practice) and IWC litter will be compared on six small watersheds at the USDA-ARS Riesel Watersheds.
