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 States, 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 /> Land Capability Classification—Grand County Area,Colorado <br /> Map unit symbol and name Pct.of Component name Land Capability <br /> map unit Subclass <br /> Nonirrigat Irrigated <br /> ed <br /> 66—Quander stony loam, 15 to 55 percent <br /> slopes <br /> 1 <br /> 90 1 Quander 7e — <br /> 93—Youga loam, 1 to 6 percent slopes <br /> 85�Youga 6cl 6c <br />
