'''Land capability classification''' is - according to the [[USDA]] terminology - ''"a system of grouping [[soil]]s 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."<ref>[http://www.nrcs.usda.gov/technical/NRI/1997/summary_report/glossary.html List of USDA terminology]</ref>''
