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.

Notes

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)

PAST

Pasture System -- pasture > 70% of farmland

DOMSP

Specialty System -- special crops (corn, sunflowers, potatoes, etc.) > 10% of cultivated land

DOMWS

Wheat and Summerfallow System -- wheat > 50% of cultivated land and summerfallow > 20% of cultivated land

DOMWW

Wheat System -- wheat > 50% of cultivated land and summerfallow < 20% of cultivated land

DOMWO

Wheat and Oilseeds System -- wheat > 30% of cultivated land and oilseeds > 20% of cultivated land

DOMWB

Wheat and Barley System -- wheat > 30% of cultivated land and barley > 20% of cultivated land

DOMBB

Barley System -- barley > 25% of cultivated land

DOMBF

Barley, Feeds and Forages System -- barley > 25% of cultivated land, and feed grains plus forages are 25% to 50% of cultivated land

DOMFF

Feeds and Forages System -- feed grains plus forages > 50% of cultivated land

MIXED

Mixed System -- farms not classified in any of the above systems

System Modifier

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.
