Land capability classification 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."
