Not Suitable (N) - with severe limitations which are difficult to overcome in time or cannot be corrected at currentlyacceptable cost. Limitations are so severe that prevent successful sustained use of the land in the given manner.

Highly Suitable (S1) - with none to slight limitations for any given use. Slight limitations will not significantly reduceproductivity or benefit nor raise inputs above an acceptable level.

Moderately Suitable (S2) - with limitations which are moderately severe for sustained application for a given use.Limitations will moderately reduce productivity or benefits. Requires increased input to the extent that the overalladvantage to be gained will be inferior to that expected on S1 land.

Marginally suitable (S3) - with limitations which in aggregate are severe for sustained application of a given use andwill significantly reduce productivity or benefits. Limitations will significantly increase required inputs, that this
