Custom Soil Resource Report <br />acidity or alkalinity, an acceptable salt and sodium content, and few or no rocks. The <br />water supply is dependable and of adequate quality. Prime farmland is permeable to <br />water and air. It is not excessively erodible or saturated with water for long periods, <br />and it either is not frequently flooded during the growing season or is protected from <br />flooding. Slope ranges mainly from 0 to 6 percent. More detailed information about <br />the criteria for prime farmland is available at the local office of the Natural Resources <br />Conservation Service. <br />For some of the soils identified in the table as prime farmland, measures that overcome <br />a hazard or limitation, such as flooding, wetness, and droughtiness, are needed. <br />Onsite evaluation is needed to determine whether or not the hazard or limitation has <br />been overcome by corrective measures. <br />A recent trend in land use in some areas has been the loss of some prime farmland <br />to industrial and urban uses. The loss of prime farmland to other uses puts pressure <br />on marginal lands, which generally are more erodible, droughty, and less productive <br />and cannot be easily cultivated. <br />Unique farmland is land other than prime farmland that is used for the production of <br />specific high-value food and fiber crops, such as citrus, tree nuts, olives, cranberries, <br />and other fruits and vegetables. It has the special combination of soil quality., growing <br />season, moisture supply, temperature, humidity, air drainage, elevation, and aspect <br />needed for the soil to economically produce sustainable high yields of these crops <br />when properly managed. The water supply is dependable and of adequate quality. <br />Nearness to markets is an additional consideration. Unique farmland is not based on <br />national criteria. It commonly is in areas where there is a special microclimate, such <br />as the wine country in California. <br />In some areas, land that does not meet the criteria for prime or unique farmland is <br />considered to be farmland of statewide importance for the production of food, feed, <br />fiber, forage, and oilseed crops. The criteria for defining and delineating farmland of <br />statewide importance are determined by the appropriate State agencies. Generally, <br />this land includes areas of soils that nearly meet the requirements for prime farmland <br />and that economically produce high yields of crops when treated and managed <br />according to acceptable farming methods. Some areas may produce as high a yield <br />as prime farmland if conditions are favorable. Farmland of statewide importance may <br />include tracts of land that have been designated for agriculture by State law. <br />In some areas-that are not identified as having national or statewide importance, land <br />is considered to be farmland of local importance for the production of food, feed, fiber, <br />forage, and oilseed crops. This farmland is identified by the appropriate local agencies. <br />Farmland of local importance may include tracts of land that have been designated <br />for agriculture by local ordinance. <br />Report Prime and other Important Farmlands (Proposed <br />Frentress Gravel Pit) <br />Prime and-other ImporWnt`Fatrnlands-zRoutt Area,: Colorado, parts of RFo Slane and Rouff Courses <br />Map Symbol Map unit W"e FaYmia'nd Classification <br />19D Evanot loam, 1 to 12 percent slopes <br />102 Shermap loam, cool, 40 to 65 percent slopes Not prime farmland <br />28
