Land capability classification is - according to the USDA terminology - "a system of grouping soils primarily on the basis of their capability to produce common cultivated crops and pasture plants without deteriorating over a long period. Land capability classification is subdivided into capability class and capability subclass nationally.
- Capability class
- The broadest category in the system. Class codes I to VIII indicate progressively greater limitations and narrower choices for agriculture. The numbers are used to represent both irrigated and nonirrigated land capability.
- Capability subclass
- The second category in the system.
- Class codes
- e (erosion problems),
- w (wetness problems),
- s (root zone limitations), and
- c (climatic limitations)
are used for land capability subclasses."[1]
