The Important Farmland survey area is based on National Resource Conservation Service (NRCS) modern soil surveys covering most non-governmental lands in California; 49 counties are fully or partially surveyed at this time. Soil surveys specific to National Forests or other government land units are not surveyed. Beginning in 2002, SSURGO digital soil information was incorporated into the San Diego County Important Farmland data. Data subsequent to 2002 may have acreage and soil line differences due to incorporation of newer NRCS-SSURGO editions. Prior to the availability of SSURGO, soil information was hand-transferred from the paper soil surveys. Older versions of the data have not been modified. The land use minimum mapping unit of ten acres has not changed, but digital soil units of down to one acre occur in the SSURGO-enhanced Important Farmland data. Due to the interaction of land use and soil components of the data, incorporation of SSURGO may also result in units of less than ten acres for categories such as Other Land (or Nonagricultural and Natural Vegetation). For more information on SSURGO, contact the USDA-Natural Resources Conservation Service: http://soildatamart.nrcs.usda.gov/ |

The data is a current inventory of agricultural resources. This data is for general planning purposes and has a minimum mapping unit of ten acres.</SPAN></P><P><SPAN /></P><P><SPAN>Prime Farmland (P</SPAN></P><P><SPAN>Irrigated land with the best combination of physical and chemical features able to sustain long term production of agricultural crops.

This land has minor shortcomings, such as greater slopes or less ability to store soil moisture than Prime Farmland. Land must have been used for production of irrigated crops at some time during the four years prior to the mapping date</SPAN></P><P><SPAN>Unique Farmland (U)</SPAN></P><P><SPAN>Lesser quality soils used for the production of the state's leading agricultural crops. This land is usually irrigated, but may include non-irrigated orchards or vineyards as found in some climatic zones in California. Land must have been cropped at some time during the four years prior to the mapping date</SPAN></P><P><SPAN>Farmland of Local Importance (L)</SPAN></P><P><SPAN>Land that meets all the characteristics of Prime and Statewide, with the exception of irrigation. Farmlands not covered by the above categories but are of significant economic importance to the county. They have a history of good production for locally adapted crops. The soils are grouped in types that are suited for truck crops (such as tomatoes, strawberries, cucumbers, potatoes, celery, squash, romaine lettuce, and cauliflower) and soils suited for orchard crops (avocados and citrus)</SPAN></P><P><SPAN>Grazing Land (G)</SPAN></P><P><SPAN>Land on which the existing vegetation is suited to the grazing of livestock. This category is used only in California and was developed in cooperation with the California Cattlemen's Association, University of California Cooperative Extension, and other groups interested in the extent of grazing activities</SPAN></P><P><SPAN>Urban and Built-Up Land (D)</SPAN></P><P><SPAN>Urban and Built-Up land is occupied by structures with a building density of at least 1 unit to 1.5 acres, or approximately 6 structures to a 10-acre parcel. Common examples include residential, industrial, commercial, institutional facilities, cemeteries, airports, golf courses, sanitary landfills, sewage treatment, and water control structures</SPAN></P><P><SPAN>Other Land (X)</SPAN></P><P><SPAN>Land which does not meet the criteria of any other category. Typical uses include low density rural development, heavily forested land, mined land, or government land with restrictions on use.</SPAN></P><P><SPAN>Water (W)</SPAN></P><P><SPAN>Water areas with an extent of at least 40 acres.</SPAN></P><P><SPAN>Area not mapped (Z)</SPAN></P><P><SPAN>Area which falls outside of the NRCS soil survey.
