'The soils are elnssified according to <br />degree and kind of pereanent limitation, but vithout consideration of enter <br />and generally erpe.^.sive lnndformir.g that would change Lhe slope, d:;th, or <br />other characterietic.s of the soils; and vithout consideration of possible but <br />unlikely motor reclasatton protects. <br />Hcran :::morals are used to shoe the 4 broad Capability Classes and letter~~ <br />f'.1.1~: the class numeral to indicate the principal problem or hat~-~. Classe•~ <br />r.>•ri :,ub-classes used sre as follows: <br />Class I - Fev c+r no liritnr,ions that restrict choice of crops or :r. ;:ir <br />conaetvatlon measures. <br />L'l~.ss II - Some limitations that reduce the choice of crops or rer,:!^e <br />~drratc roneervatlor. measures. <br />C=ass IIi - Severe limitations that reduce choice of crops or require <br />special conservation practises or both. <br />Clnsa IY - Very sever- limitations that restrict the choice of crops, require <br />very careful wnnagement, or both. <br />Clans V - Hot suited for cultivation but has few or no hazards when used for <br />pasture, range, woodland or viidllfe. <br />Class VI - Not suited for cultivation. Severe limitations. Suited for range, <br />pasture, woodland or wildlife vith.caretul management and needed conservation <br />practices. <br />~lmea VII - Not suited for cultivation. Very severe limitations. Suited for <br />.range, woodland or vi131ife uses if carefully managed. Usually cannot apply <br />physical proctisea eucn as pitting, furrowing, seeding, etc, <br />Clas^ VIII - Not suited for cultivation, range, pasture or woodland. Suited <br />only for recreation, wildlife, voter supply or esthetic purposes. <br />e - Erosion by wind or water in the motor problem. <br />v - f5ccessive voter such as wetness, overflow, or high water table. <br />s - Motor problem is in the soil. It my be too shallow, too heavy, stony, <br />low in fertility, salty, alkaline or have low moisture capacity. <br />c - Climate is the mat or hazard. Growing season may be very short, there is <br />a shortage of rainfall or both. . <br />Eznnples <br />IIIe - Class III land where erosion is the. mat or hazard: <br />IYc -Class IV lend where the climate is the motor problem. <br />J <br />
