Minnesota ranks third in the United States for crop production totaling $14.6 billion with nearly half of all lands dedicated to crops. Improving data availability for farmers, government agencies, and researchers will inform decisions in improving conservation practices and crop yields. This project will create and disseminate the first open map of Minnesota farm fields, and produce several examples to demonstrate to policy makers and stakeholders how the farm field data can be used to improve conservation practices and crop yields. We will use satellite imagery and rigorous, reproducible, and robust geocomputational methods running on supercomputers to delineate and map each field. The project has several partners including the Institute on the Environment and Minnesota IT Services and has contacts with state agencies and policy makers. Findings from this study will advance research and inform agriculture practices and public policy across Minnesota and the United States.
