TABLE 2.04.3-2 CAPABILITY GROUPS OF SOILS • SUN COAL COMPANY - MEADOWS N0. 1 ROUTT COUNTY, COLORADO Capability classification is the grouping of soils to show, in a general way, their suitability for most kinds of farming. It is a practical classification based on limitations of the soils, the risk of damage when they are used, and the way they respond to treatment. The soils are classified according to degree and kind of permanent limitation, but without consideration of major and generally expensive landforming that would change the slope, depth, or other characteristics of the soils, and without consideration of possible, but unlikely, major reclamation projects. Roman numerals are used to show the three broad Capability Classes, and letters follow the class numeral to indicate the principal problem or hazard. Classes and sub-classes used are as follows: Class I - Few or no limitations that restrict choice of crops or require conservation measures. Class II -Some limitations that reduce the choice of crops or require moderate conservation measures. Class III - Severe limitations that reduce choice of crops or require special conservation practices, or both. • Class IV -Very severe limitations that restrict the choice of crops, require very careful management, or both. Class V - Not suited for cultivation, but has few or no hazards when used for pasture, range, woodland, or wildlife. Class VI -Not suited for cultivation. Severe limitations. Suited for•,range, pasture, woodland, or wildlife with careful management and needed conservation practices. Class VII -Not suited for cultivation, range, pasture, or woodland. Suited only for recreation, wildlife, water supply, or esthetic purposes. e -Erosion by wind or water is the major problem. w - Excessive water such as wetness, overflow, or high water table. s - Major problem is in the soil. It may be too shallow, too heavy, stony, low in fertility, salty, alkaline, or have low moisture capacity. c - Climate is the major hazard. Growing season may be very short, there is a shortage of rainfall, or both. Examples: IIIe - Class III land where erosion is the major hazard. IVc -Class IV land where the climate is the major problem. - 54 - (Rev. 5/86)
