WebThe EC map is just showing the areas that conduct electricity at a high rate (in pink) and low (in dark blue). There are three metrics that normally affect soil conductivity: moisture (water content), texture (clay content), and salinity. These are very inter-related, as we know higher clay content will lead to increased water retention. Soil EC does not directly affect plant growth but has been used as an indirect indicator of the amount of nutrients available for plant uptake and salinity levels. EC has been used as a surrogate measure of salt concentration, organic matter, cation-exchange capacity, soil texture, soil thickness, nutrients (e.g., … See more High EC can serve as an indication of salinity (EC > 4 dS/m) problems, which impede crop growth (inability to absorb water even when present) and microbial activity (tables 2 and 3).
