This function determines the suitability class to which a given indicator value falls based on the crop requirement
Input indicator value.
The crop of interest for which suitability is determined.
The suitability factor for crop requirement. Example factors include: rain, slope, carbonate, EC, ESP, depth, ph, temperature,
The output is rainfall suitability class for the crop. The output is integer value for suitability class: 1- highly suitable; 2 - moderately suitable; 3 - marginally suitable; 4 - currently not suitable; 5 - not suitable
This function assumes rainfall as the source of water for crop development. The input slope value must be in degrees
