Summary

This metadata record describes a computed ratio of county acres of farmland reported in agricultural conservation programs to the total acres of farmland reported for the county. Acres in conservation programs are for the 2012 time period, and reported by survey from the U.S. Department of Agriculture, Farm Field Survey. Acres of total farmland were used from the U.S. Department of Agriculture, 2012 Census of Agriculture. The ratio is intended to provide an indication of the intensity of agricultural management practices.

Purpose

This data set was created by the U.S. Geological Survey's (USGS) Hydrologic Systems Team which is part of the USGS National Water Quality Program (NWQP). This effort was undertaken to estimate the fraction of farmland potentially in an agricultural conservation program. These values were assigned to NHDPlusV2.1 flowline catchments and upstream river networks to support statistical analysis, map display, and model parameterization.
