1. Evaluation of Irrigation Application Management Practices to Protect Groundwater QualityAgricultural management practices relative to irrigation application and type and frequency of nitrogen fertilizer application can impact levels of nitrates in groundwater. In recent history, high levels of nitrates were reported in public water supply wells in Goshen County, WY. Subsequent research efforts concluded that likely sources of nitrate were organic soil nitrogen and ammonium or nitrate fertilizer. Some focus was then turned to agricultural production higher up in the watershed. Best... K. Reddy, A. Wann, C. Wenzel |
2. Sustaining Agriculture and the Environment Through Healthy SoilsSoil health can be defined as the continued capacity of soil to function as a vital living ecosystems that sustains plants, animals, and humans. Land management practices that enhance soil health offer many opportunities to respond effectively to current challenges to agricultural sustainability and environmental quality. Practices such as cover crops and no-till can enrich mineral soils with organic carbon, enhance water infiltration, and increase the available water holding capacity... S. Shafer |
