Cover crops work to filter out agricultural runoff which inundates surface water with nutrients and chemicals during the spring/fall. EWG uses remote sensing and GIS to track the progress and adoption of cover crops. EWG is sending a team of analysts through the agricultural landscape to collect GPS locations of cover crops to validate satellite analysis. We are also hoping to collect images of cover crops, erosion on fields and other various cover types. Previous Report: http://bit.ly/2na4wjd
