1. Sheep Grazing Effect on Dryland Soil Carbon and Nitrogen in the Wheat-fallow SystemWeed control by sheep grazing during fallow periods in the dryland wheat-fallow system may influence soil C and N levels. The effects of fallow management for weed control and soil water conservation [sheep grazing (grazing), herbicide application (chemical), and tillage (mechanical)] and cropping sequence [continuous spring wheat (CSW), spring wheat-fallow (SW-F), and winter wheat- fallow (WW-F)] on wheat biomass (stems + leaves) yield and soil organic C (SOC) and total N (STN) at the 0-120 cm...

2. Interagency Cooperation to Improve Nitrogen Management for Water Quality ProtectionAgriculture and water are inseparable in a semiarid region such as Colorado. Adequate clean water supplies for drinking, agriculture, industry, and recreation are critical for the lifestyle Coloradans enjoy. The Agricultural Chemicals and Groundwater Protection Program (ACGPP) was created by the Colorado legislature in 1990. The purpose of this unique program is to reduce the potential impairment of groundwater by agricultural chemicals have on groundwater and the environment by preventing groundwater... T. Bauder, E.
