Crop Suitability

To assess the suitability of the land for selected crops the soil attributes and land qualities are compared with the individual crop requirements for optimum growth. A manual approach was taken for matching soil map units and crop requirements with land qualities. This approach produced robust results and gave sensible estimates for the crop suitability.
