1. Soil Carbon Sequestration in Agriculture- Research Efforts in the Central U.S.Since the late 1800's fossil fuel use, expansion of cultivated agriculture, and forest clearing have led to an increase in atmospheric C02 from 260 pprn to current levels >370 ppm (IPPC, 1995). Most of the recent increase in COz has been attributed to combustion of fossil fuels for energy and transportation. This increase in atmospheric COz potentially impacts climate, as it is a greenhouse gas. It has been estimated that 20-40% of targeted emission reductions in the U.S. can be met by carbon sequestration... |
2. Exploratory analysis of event-based edge-of-field phosphorus lossesUnderstanding how the timing of management activities, particularly manure and fertilizer applications, impacts P losses in runoff can improve farmers’ decisions on when to apply nutrients. The University of Wisconsin Discovery Farms and Discovery Farms Minnesota have been monitoring edge-of-field nutrient losses since 2004. This data set includes over 125 site-years of runoff across 26 fields and includes 1574 individual runoff events. The objectives of this study are to: (i) determine... |
