Percent of Cropland in Hayland, 1997
This map shows the general distribution of Hayland production in the United States in 1997 as a percentage of total cropland. There were 56,109,700 acres of hayland in 1997.
Cautions for this Product:
This map displays areas where hay production makes up varying proportions of total cropland. It may not be appropriate for identifying, even on a national basis, the amount of hay grown.

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.

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]
A sub-category of Cropland managed for the production of forage crops that are machine harvested. These crops may be grasses, legumes or a combination. Hayland also includes land in set-aside or other short-term agricultural programs. [NRI-97]
A hierarchical system developed by the U.S. Geological Survey that divides the United States and the Caribbean into 21 major regions, 222 subregions, 352 accounting units, and further subdivided into 2,150 cataloging units that delineate river basins having drainage areas usually greater than 700 square miles. [USGS]
A term that includes categories of land cover and categories of land use. Land cover is the vegetation or other kind of material that covers the land surface. Land use is the purpose of human activity on the land; it is usually but not always related to the land cover. The NRI uses the term (land cover/use) to identify the categories that account for all the surface area in the United States [BS-1982; NRI-97]
Includes land in horticulture that is not double- cropped; or land in hay which had not been in row or close-grown crops for any of the previous three years.
Includes all land and water areas where the ownership is by private, municipal, county or parish, state, Indian tribal, individual trust, the Tennessee Valley Authority, or areas under temporary control of a Federal, state, county or municipal agency or government for foreclosure or nonpayment of taxes.
