CO-CCNS-2 CAPABILITY GROUPS OF SOILS Capability classification is the grouping of soils to shoe, in a general way, their suitability for moat kinds of farming. It is a practical classification based on limitations of the soils, the risk of damage when they are used, and Lhe ray they respond to treatment. The soils are classified according to degree and kind. of permanent limitation, but vithout consideration of maJor and generally a:pensive landforming that would change the slope, depth, or other characteristics of the soils; and vithout consideration of possible but unlikely maJor reclamation protects. Roman numerals are used to shoe the (! broad Capability Cis^ses and letters follw Lhe class numeral to indicate the principal proble¢ or hsiard. Classes and sub-classes used are ns follors: Clas^ I - Fev or no limitations that restrict choice of crops or require conservation measures. Class II - Some limitations that reduce the choice of crops or requir: moderate conservation measures. Class III - Severe limitations that reduce choice of crops or require special conservation practices or both. Class IY - Very severe limitations that restrict Lhe choice of crops, require very careful management, or both. Class V - Not suited for cultivation but has few or na hazards rhea used for pasture, range, woodland or wildlife. Class VI - Not suited for cultivation. Severe limitntione. Suited for range, pasture, woodland or rildlite with careful management and needed conservation practices. Class YII - Not suited for cultivation. Very severe limitations. Suited for range, woodland or wildlife uses if carefully managed. Usually cannot apply physical practices such as pitting, furroring, seeding, etc. Class VIII - Aot suited for cultivation, range, pasture or woodland. Suited only for recreation, wildlife, rater supply or esthetic purposes. e - F1'osion by wind or eater le the mater problem. v - EScceasive rater ouch as retnesa, overflow, or high voter table. s - Mator problem is in Lhe soil. It tay be too shallow, too heavy, stony, for in fertility, salty, alkaline or have low moisture capacity. c - Climate is the mat or hazard. Crowing season may be very short, there is a shortage of rainfall or both. FScsmples IIIe - Class III land where erosion is the motor hazard. IYc - Class IY land where the climate is the maJor problem.
