The Land Capability Classification for Agriculture has as its objective the presentation of detailed information on soil, climate and relief in a form which will be of value to land use planners, agricultural advisers, farmers and others involved in optimising the use of land resources. The classification ranks land on the basis of its potential productivity and cropping flexibility determined by the extent to which its physical characteristics (soil, climate and relief) impose long term restrictions on its agricultural use.
THE CLASSES
Class 1. Land capable of producing a very wide range of crops with high yields
Class 2. Land capable of producing a wide range of crops with yields less high than Class 1.
Class 3. Land capable of producing good yields from a moderate range of crops.
Class 4. Land capable of producing a narrow range of crops.
Class 5. Land suited only to improved grassland and rough grazing.
Class 6. Land capable only of use as rough grazing.
Class 7. Land of very limited agricultural value.
THE DIVISIONS
A division is a ranking within a class. As the requirements of the crops suited to Classes 1 and 2 are fairly stringent, land in these classes has inherently low degrees of internal variability and no divisions are present.
The requirements of crops grown in the remaining classes are less rigorous, consequently land included is more variable in character.
