This project utilizes Conservation Effects Assessment Project (CEAP) watersheds in Lower Chesapeake Bay area.This dataset supports spatial analysis of Legacy Phosphorus dynamics in the Lower Chesapeake Bay watershed. It includes tabular data, shapefiles, and raster maps derived from field measurements and Random Forest modeling.The main data file contains multiple sheets to guide the user, see 'readme' and 'column descriptions' for details. The 'Data Summary' sheet has the primary data in tidy format.This project is funding by USDA-NRCS Conservation Effects Assessment Project (Agreement NRC21IRA0010879) including USDA Legacy Phosphorus Study, with additional funding provided by USDA-ARS intramural projects under Natural Resources and Sustainable Agricultural Systems National Programs, as well as the USDA Long-Term Agroecosystem Research (LTAR) Network.
