CO-CQl$-2 CAPABILITY GROUPS OF SOILS Capability claesificntion is the grouping of soils to shoe, in n general vny, their suitability for moat kinds of farming. It is n practical clnsa:Lficntion based on limitations of the soils, the risk of damage when they are used, end the way they respond to Lrentment. The soils are classified nceordin„ to degree and kind of permment limitation, Dut without coneiderntion of motor and generally expensive landforeing that would ehnnge the slope, depth, or other cherecteristlcs of the soils; sad without coneiderntion of poss:lble but unlikely motor reclamation protects. Roman numerals are used to shoe the 8 broad Capability Classes and letters follow the class numeral to indicate the principal problem or hazard. Classes and sub-closes used are ss follows: Class I - Fev or no limitations that restrict choice of scope or require conservation measures. Class II - Sole limitations thst reduce the choice of crops or require moderate consecration measures. Class III - Severe limitations that reduce choice of crops or require special conservation practices or both. Class IY - Very severe limitations that'restrlct the choice of crops, require very careful management, or both. -- Class Y - Rot suited for cultivation but has few or no hasards when used for p•-ture, range, woodland or wildlife. Class VI - Rot suited for cultivation. Severe limitations. Suited for range, pasture, woodland or wildlife with careful ssnagement and needed conservation practices. Claaa VII - Rot suited for cultivation. Yery severe limitations. Suited for range, woodland or wildlife uses if carefully managed. Usually cannot apply physical practices ouch an pitting, furrowing, seeding, etc. Clue VIII - Ilot suited for cultivation, range, pasture or woodland. Suited only for recreation, wildlife. eater supply or esthetic purposes. e - Erosion by wind or eater is the mayor problem. w - iscceaaive eater such as wetness, overflow, or high water table. s - Motor problem 1a in the soil. IC mq be too shallow, too heavy, stony, lac fn fertility, salty, alkaline or have low mofature capacity. c - Climate 1a the motor hasard. Crowing season may be very short, there is r shortage of reinfal! or both. Examples: IIIe - Class III land where erosion is the rotor hesard. IYc - Gass IY lead where the climate is the motor problem.
