The suitability of land for use without damage. Land capability (as ordinarily used in the United States) is an expression of the effect of physical land conditions, including climate, on total suitability for use without damage, for crops that require regular tillage, for grazing, for woodland and for wildlife. Land capability invol [..]

1.

An attribute of land that can be measured or estimated and that can be employed as a means of describing land qualities or distinguishing between land units of differing suitabilities for use.

A means of referring to systems of grouping land on the basis of its physical characteristics (including vegetation) without explicit assessment of suitability for kinds of land use.

The total area of sole crops required to produce the same yields as would be obtained when they are intercropped. The total land-equivalent ratio is the sum of the partial land-equivalent ratios of each component. Consideration has to be given to the planting density of the sole crops and the intercrop and to the management levels if [..]

The process of assessment of land performance when used for specified purposes.

An area within which, for most practical purposes, biophysical conditions are uniform. All land within a land facet can be expected to respond similarly to management. Land facets often occur in regular sequences, within a land system (for example, hillcrest to valley floor). See also

Genetically variant population originating through selection and propagation by individual farmers, or in small areas of geographic isolation. See also

The partial suitability of a land unit for a land-utilization type, based on one land quality, or a partial set of land qualities. Land-suitability ratings are combined to give a land-suitability class.
