Summary

This dataset contains catchment-level estimates of nitrogen and phosphorus fertilizer use, for agricultural lands, for the conterminous U.S., for 2012. An approach was developed to relate farm commercial fertilizer sales data from the Association of American Plant Food Control Officials (AAPFCO) to a set of explanatory variables using spatially-referenced modeling methods. Separate models for nitrogen and phosphorus are developed to estimate elemental fertilizer use on agricultural lands for the conterminous U.S. at the National Hydrography Dataset Plus version 2 (NHDPlusV2) catchment scale. The approach builds on earlier efforts that use Association of American Plant Food Control Officials (AAPFCO) data on fertilizer sales to provide [...]

Purpose

Elemental nitrogen and phosphorus fertilizer use on agricultural cropland is estimated for the conterminous United States for the year 2012 at the National Hydrography Dataset Plus version 2.0 (NHDPlusV2) catchment scale. This information will prove useful for water-quality models that estimate total-nitrogen and total-phosphorus loads to streams and for other studies requiring fertilizer-use estimates related to agricultural cropping practices in the United States.
