It 1s a practical :lua:ll:cat:u~t <br />base3 on limitations of the soils, Lhs rink of dosage when they ass usrl, a::d <br />zhe vcy they respond to treatment. The soils are classified a:eor8le/ to <br />degree sad kind of per~r.ent lieitation, but without eonsideratio:t of na~er <br />and generally eYFe.^.slve landfor~irg that would change the slops, depth, or <br />other chsracteriatics of the soils; and without eonsideration_of poaslbl~ Dut <br />unlikely mayor recleiation pro~ecta. • <br />Rcrar.:.aerals are used to show the 3 broad Cape.billty Classes std letter4 <br />!`.t?:~ the class n•uxeral to indicate the principal problec or has-.-'_. Class-~ <br />pub-classes used are os follors: <br />Class I - Fey nr no llrit.aLSans that restrict choice af.crops or t•~:.ir~ <br />conservation eeasurea. <br />C1•ss II - Some limitations that reduce the choice of crops or rzq:!re <br />sdtrnte ronservatior. measures. . <br />Class III - Severe l:citntions that reduce choice of craps or ra~uire <br />• special conservation practices or Doth. <br />C1ass.IV - Very sever- limitations that restrict the choice of crops, re~luire <br />very careful sanagement, ar bath. <br />Class V - Not suited for cultivation but has few or no hsaards v1!atf u>aad for <br />pastu.-e; range, woodland or viidllfe. <br />Class VI - Not suited for cultivation. Severe limitations. Suited for range, <br />posture, woodland or wildlife with careful nanagerent and needed conservation <br />practices. <br />~lasa YII - Not suited for cultivation. Very severe limitations. Suited for <br />range, woodland or wildlife uses'if carefully managed. Usually cannot apply <br />physical practices such es pitting, furioving, seeding, ate. <br />Claaa VIII - Not suited for cultivation, range, pasture or vooJland. Suited <br />only for recreation, vildlite, eater supply or esthetic purposes. <br />e - E?osion by vied or valet is the oa~or problem. <br />v - ESccessivt voter such as wetness, overflow, or high voter tablt. <br />s - kfalor problem is in the soil. IL say be Loo shellov, too haarp, stony, <br />low in fertility, salty, alkaline or have low eoiature eepaclty. <br />e - Cliaate is the mayor hazard. Crowing season may be very short, there !s <br />a shortnRe of rninfell or both. <br />• Ezanplts• <br />IIIe - Class III land where erosion 1s the mayor hexard. <br />.: <br /> <br />7Vc - Class IV le-~d where the climate is the nn~or problem. <br />
