Acres of Cropland Converted to Conservation Reserve Program Land, 1982 - 1992
This dot density map show acres of cropland that were converted to Conservation Reserve Program (CRP) land between 1982 and 1992. Each dot represents 1,000 acres. Dots were aggregated by and placed randomly within each 8-digit hydrologic unit. This map reflects CRP contracts through the thirteenth sign-up.

NRI sample data are generally reliable at the 95% confidence interval for state and certain broad substate area analyses. Generally, analyses that aggregate data points by smaller geographic areas and/or more specific criteria result in fewer data points for each aggregation and therefore less reliable estimates. NRI maps reflect national patterns rather than site- specific information.

Conservation Reserve Program (CRP):
A Federal program established under the Food Security Act of 1985 to assist private landowners to convert highly erodible cropland to vegetative cover for 10 years. [NMCSP]
A Land cover/use category that includes areas used for the production of adapted crops for harvest. Two subcategories of cropland are recognized: cultivated and noncultivated. Cultivated cropland comprises land in row crops or close-grown crops and also other cultivated cropland, for example, hayland or pastureland that is in a rotation with row or close-grown crops. Noncultivated cropland includes permanent hayland and horticultural cropland. [NRI-97]
