This EnviroAtlas national map displays the application rate of phosphorus (P) as manure on croplands in the conterminous United States (excluding Hawaii and Alaska) for the year 2012 by 12-digit HUC. These data are based on county-level data on P as recoverable manure from concentrated animal feeding operations (CAFOs) from the International Plant Nutrition Institute (IPNI) and cropland area from the USGS's U.S. conterminous wall-to-wall anthropogenic land use trends (NWALT) 2012 land cover data. These are thus not actual application rates but rather estimated rates based on the production of recoverable manure and the amount of agricultural lands close by. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).
