Percent Acres Class I 8,060 12.4 Class II 27,755 42.7 Class III 14,495 22.3 Class IV 14,690 22.6 Definition of Land Classes Class I-Very good land that can be cultivated safely with ordinary good farming methods and good management practices; subject to very slight or no continuing limitations in use or risk of damage because of permanent land characteristics. Class I land is nearly level, deep, productive, well drained, easily worked soil and is potentially productive crop land that is capable of intensive cultivation. Class II-Good land that can be cultivated with easily-applied, protective measures; subject to moderate limitations in use, or moderate risks of damage, because of permanent land characteristics. Examples of the limitations of Class II are: gentle slopes, moderate susceptibility to erosion, moderate depth-light or heavy texture, moderate salinity-easily corrected and moderate wetness. Class III-Moderately good land that can be used regularly for crops in a good rotation but needs intensive treatments or complex farming practices for permanent use; subject to severe limitations in use or severe risks of damage, because of permanent land characteristics. Examples of Class III are: moderately steep slopes, high susceptibility to erosion, excessive wetness, moderate to severe alkali and salinity, shallow to inhibitory layers, very heavy or very light textures, and low inherent fertility. |
