5.5 Electro-Conductivity (EC): 
Soil Electrical conductivity is the third parameter used to classify grape site suitability. Geo-coordinates and GSI relative soil EC ratings used to create the electrical conductivity map. The EC variation in the study area ranges from 0.1 to 1 Ds/m. It indicates a rising tendency in the northwest and a decreasing trend in the northeast of the research region. The highest EC, 1 Ds/m, is found in the northwest, while the lowest EC, 0.1 Ds/m, is found in the northeast. The map is rated and graded according to the NBSS and LUP criteria for grape suitability classes. (See Table 4 )
