Custom Soil Resource Report <br />Capability classes, the broadest groups, are designated by the numbers 1 through <br />8. The numbers indicate progressively greater limitations and narrower choices for <br />practical use. The classes are defined as follows: <br />- Class 1 soils have slight limitations that restrict their use. <br />- Class 2 soils have moderate limitations that restrict the choice of plants or that <br />require moderate conservation practices. <br />- Class 3 soils have severe limitations that restrict the choice of plants or that <br />require special conservation practices, or both. <br />- Class 4 soils have very severe limitations that restrict the choice of plants or <br />that require very careful management, or both. <br />- Class 5 soils are subject to little or no erosion but have other limitations, <br />impractical to remove, that restrict their use mainly to pasture, rangeland, <br />forestland, or wildlife habitat. <br />- Class 6 soils have severe limitations that make them generally unsuitable for <br />cultivation and that restrict their use mainly to pasture, rangeland, forestland, or <br />wildlife habitat. <br />- Class 7 soils have very severe limitations that make them unsuitable for <br />cultivation and that restrict their use mainly to grazing, forestland, or wildlife <br />habitat. <br />- Class 8 soils and miscellaneous areas have limitations that preclude <br />commercial plant production and that restrict their use to recreational purposes, <br />wildlife habitat, watershed, or esthetic purposes. <br />Capability subclasses are soil groups within one class. They are designated by <br />adding a small letter, e, w, s, or c, to the class numeral, for example, 2e. The letter e <br />shows that the main hazard is the risk of erosion unless close -growing plant cover is <br />maintained; w shows that water in or on the soil interferes with plant growth or <br />cultivation (in some soils the wetness can be partly corrected by artificial drainage); <br />s shows that the soil is limited mainly because it is shallow, droughty, or stony; and <br />c, used in only some parts of the United Stales, shows that the chief limitation is <br />climate that is very cold or very dry. <br />In class 1 there are no subclasses because the soils of this class have few <br />limitations. Class 5 contains only the subclasses indicated by w, s, or c because the <br />soils in class 5 are subject to little or no erosion. <br />Report—Land Capability Classification <br />1 Land Capability Classiflcation—Huarfano County Area, Colorado <br />Map unit symbol and nameI Pct. of I Component name I Land Capability <br />map unit Subclass <br />16—Fansita very gravelly sandy loam, 10 to 35 <br />percent slopes <br />Nonirrlgat Irrigated <br />ed <br />85 Farisila I 7s — <br />11 <br />
