CAPABILITY GROUPS OF SOILS <br />Capability classification is the grouping of soils <br />to show, in a general why, their suitability for most <br />kinds of farming. It is a practical classification <br />based on limitations of the soils, the risk of damage _' <br />when they are used, and the way they respond to treat- <br />ment. The soils are classified according to degree and <br />kind of permanent limitation, but without consideration <br />of major and generally expensive landforming that would <br />change the slope, depth, or other characteristics of <br />the soils; and without consideration of possible but <br />unlikely major reclamation projects, <br />Roman numerals are used to show the eight broad <br />Capability Classes and letters follow the class numeral <br />to indicate the principal problem or hazard. Classes <br />• and sub-classes used are as follows: <br />Class I - Few or no limitations that restrict <br />choice of crops or require conservation measures. <br />Class II - Some limitations that reduce the choice <br />of crops or require moderate conservation measures. <br />Class III - Severe limitations that reduce choice <br />of crops or require special conservation practices or <br />both. <br />Class IV - Very severe limitations that restrict <br />the choice of crops, require very careful management, <br />or both. ' <br />Class V - Clot suited for cultivation but has few <br />or no hazards when used for pasture, range, woodland or <br />wildlife. <br />Class VI - P]ot suited for cultivation. Severe <br />limitations. Suited for range, pasture, woodland or <br />wildlife with careful management and needed conserva- <br />• tion practices. <br />
