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 )
