Creator:: Heinrich, Aaron and Sullivan, Dan M.
Abstract:: Following the surface application of urea to soil, there is the potential for nitrogen (N) loss from ammonia (NH3) volatilization until sufficient rain or irrigation has moved it into the soil. Many studies measuring NH3 loss have used laboratory and microplot field studies. The limitation of these techniques is that...

Abstract:: Biosolids are a by-product of municipal wastewater treatment. They contain organic matter and nutrients that are beneficial for soil, crop, and livestock productivity. Raw sewage solids must be processed to meet U.S. Environmental Protection Agency (USEPA) standards before they can be called biosolids. This publication focuses on how biosolids can...

Abstract:: The fertilizer value of anaerobically-digested, dewatered biosolids in dryland cereal cropping systems was evaluated at six locations in central and eastern Washington (25 to 35 cm annual precipitation zone). Biosolids were applied at rates of 3 to 20 Mg/ha (approximately 150 to 900 kg N/ha). We measured increases in soil...
