ECSuit | R Documentation |
This function determines the suitability classes for Electrical Conductivity requirements for selected agricultural crops and forest trees
ECSuit(value, crop)
value |
Input electrical conductivity in dS/m. |
crop |
The crop of interest for which EC suitability class is sought. |
The input value can be map or just a numerical entry of electrical conductivity (ECe) of saturated paste extract or its equivalent in dS/m
The output is EC 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
Should the input value be raster map, then the output will also be a raster map of Electrical Conductivity suitability for the crop of interest
