Published by U.S. EPA Office of Research & Development (ORD) - National Exposure Research Laboratory (NERL) | U.S. Environmental Protection Agency | Metadata Last Checked: January 27, 2026 | Last Modified: 2016-10-28T00:00:00.000+00:00
This EnviroAtlas national map displays the application rate of inorganic phosphorus (P) fertilizer on agricultural land in the conterminous United States (excluding Hawaii and Alaska) for the year 2012 by 12-digit HUC. These data are based on International Plant Nutrition Institute (IPNI) compilations of county and state fertilizer sales for 2012 and cropland area from the USGS's U.S. conterminous wall-to-wall anthropogenic land use trends (NWALT) 2012 land cover data. 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).
