Abstract: The goal of the Farmland Mapping and Monitoring Program (FMMP) is to provide consistent and impartial data to decision makers for use in assessing present status, reviewing trends, and planning for the future of California’s agricultural land resources. FMMP produces Important Farmland Maps, which are a hybrid of resource quality (soils) and land use information. Data is also released in statistical formats--principally the biennial California Farmland Conversion Report. PRIME FARMLAND AS MAPPED BY FMMPIn order to be shown on FMMP’s Important Farmland Maps as Prime Farmland and Farmland of Statewide Importance, land must meet both the following criteria:Land Use:Has been used for irrigated agricultural production at some time during the four years prior to the Important Farmland Map date. Irrigated land use is determined by FMMP staff by analyzing current aerial photos, local comment letters, and related GIS data, supplemented with field verification.-- AND --Soil:The soil must meet the physical and chemical criteria for Prime Farmland or Farmland of Statewide Importance as determined by the USDA Natural Resources Conservation Service (NRCS). NRCS compiles lists of which soils in each survey area meet the quality criteria. Factors considered in qualification of a soil by NRCS include:Water moisture regimes, available water capacity, and developed irrigation water supplySoil temperature rangeAcid-alkali balanceWater tableSoil sodium contentFlooding (uncontrolled runoff from natural precipitation)ErodibilityPermeability rateRock fragment contentSoil rooting depthFor more detail about the soil criteria and mapping categories, please read this excerpt from the FMMP Guidelines. The Prime/Statewide lists for each county are available on the FMMP web site in PDF format. Any questions specific to soil qualifications for Prime Farmland or Farmland of Statewide Importance lists should be directed to your local NRCS office. For questions on compilation of the Important Farmland Maps, contact FMMP. The NRCS Soil Data Mart hosts original soil data in GIS format--see links below.Other 'Prime' Land definitionsThe term 'Prime' as it refers to rating for agricultural use has two meanings in California. FMMP determines the location and extent of 'Prime Farmland' as described above; while under the state's Williamson Act, land may be enrolled under the 'Prime Agricultural Land' designation if it meets certain economic or production criteria.

FGDC and ESRI Metadata:

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

Purpose:
NOTE: this layer consolidates all separate FMMP years into a single source. Individual years can be isolated by performing a definition query on the "upd_year" field.

The Farmland Mapping and Monitoring Program (FMMP) produces maps and statistical data used for analyzing impacts on California’s agricultural resources. Agricultural land is rated according to soil quality and irrigation status; the best quality land is called Prime Farmland. The maps are updated every two years with the use of a computer mapping system, aerial imagery, public review, and field reconnaissance.
