One of the eight classes of land in the land capability classification of the U. S. Natural Resource Conservation Service; distinguished according to the risk of land damage or the difficulty of land use; they include:
Land suitable for cultivation and other uses.
- Class I - Soils that have few limitations restricting their use.
- Class II - Soils that have some limitations, reducing the choice of plants or requiring moderate conservation practices.
- Class III - Soils that have severe limitations that reduce the choice of plants or require special conservation practices, or both.
- Class IV - Soils that have very severe limitations that restrict the choice of plants, require very careful management or both.
- Class V - Soils that have little or no erosion hazard, but that have other limitations, impractical to remove, that limit their use largely to pasture, range, woodland, or wildlife food and cover.
- Class VI - Soils that have severe limitations that make them generally unsuited for cultivation and limit their use largely to pasture or range, woodland, or wildlife food and cover.
- Class VII - Soils that have very severe limitations that make them unsuited to cultivation and that restricts their use largely to grazing, woodland, or wildlife.
