Census Land Use Data from Agroecological Resource Area (ARA) Database
LANDUSEFootnote [note 1].DAT
A land use file was developed from the same EA overlay onto the ARA polygons and was used to develop the Economic data file. The landuse data are based on an average of the mean values of all farm types within each polygon. Only dryland systems are included in this data file.
Reference: Huffman et al. (1992).
One Record Per ARA.

|SDFMTYPE||Subdominant Farmtype (See codes, below)|
|NFARM||Number of Farms Studied|
Farmland includes all land owned and rented. Cropland includes all annual crops, fallow, alfalfa, other forage crops and tame hay, but not improved pasture, other improved land, or unimproved land.
Codes for Farmtypes (DFMTYPE, SDFMTYPE)
Pasture System -- pasture > 70% of farmland
Specialty System -- special crops (corn, sunflowers, potatoes, etc.) > 10% of cultivated land
Wheat and Summerfallow System -- wheat > 50% of cultivated land and summerfallow > 20% of cultivated land
Wheat System -- wheat > 50% of cultivated land and summerfallow < 20% of cultivated land
Wheat and Oilseeds System -- wheat > 30% of cultivated land and oilseeds > 20% of cultivated land
Wheat and Barley System -- wheat > 30% of cultivated land and barley > 20% of cultivated land
Barley System -- barley > 25% of cultivated land
Barley, Feeds and Forages System -- barley > 25% of cultivated land, and feed grains plus forages are 25% to 50% of cultivated land
Feeds and Forages System -- feed grains plus forages > 50% of cultivated land
Mixed System -- farms not classified in any of the above systems
05 Low percentage of pasture: pasture < 20% of farmland
06 Moderate percentage of pasture: pasture > 20% and < 70 % of farmland
eg. 05DOMWS = pasture < 20% of farmland, wheat > 50% of cultivated land, and summerfallow > 20% of cultivated land.
