Using, Mapping, and Modeling Detailed Farm Service Agency Agriculture Data
Track: Environment Management
Author(s): Harold Robinson, Greg Easson, Stephen Threlkeld
An agrichemical distribution database was created as part of an EPA Ecosystems Indicators Project for the purpose of evaluating effects of multiple stressors on agriculturally impacted wetlands. USDA Farm Service Agency data, including crop type and acreage, was collected and used to generate the database with all data aggregated into Public Land Survey (PLS) sections (nominally 1 square mile). Mapping and modeling of agrichemical distribution, inferred from crop type, acreage, and normal agrichemical application rates, has enabled researchers to select PLS sections with specific combinations of agrichemical stressors and potentially impacted wetlands.
