| This five-year project is designed to
demonstrate at field scale how new and developing technologies can
improve crop utilization of nutrients, water quality, and profits. The
stated objectives are to reduce N fertilizer usage on fields managed
with variable-rate N and to implement precision farming practices on 10
percent of row-crop acres in Missouri.
Site-specific management (also known as precision farming) improves the crop-use efficiency of fertilizer and herbicide inputs, which helps protect water resources. Site-specific management places fertilizer and herbicides on the field so the growing crop can efficiently use it. This management practice minimizes over-application and under-application, leaving less unused nutrients without sacrificing crop yield. The net result is less nutrient loading to watershed streams. Based on research by the USDA-ARS, University of Missouri Agricultural Experiment Station, and other agencies, many fields in Missouri are well suited for site-specific management. Early adopters, innovative farmers, and agricultural suppliers are moving forward to implement precision farming. The scientific basis and the potential for economic and environmental benefit for Missouri producers are compelling. To address these issues a formal outreach and Extension education program was started in 1997 to demonstrate the pollution prevention benefits of site-specific nutrient management.
