What causes salinity? What factors contribute to salinity?
In the simplest terms, salinity is the result of an accumulation of salts in soil. The source of salts in the soil is either water in or entering the soil, fertilizers, or weathering of soil and salts geologically accumulated in the soil. Irrespective of the source of the salts, the factor which contributes the most to salinity is pattern of water movement in the soil. If there are circumstances which have contributed salt, i.e., inflowing water, fertilizers, geologically sourced salts, lack of water movement or drainage through and below the root zone or depth of measurement in the soil is the single-most significant factor contributing to salinity.
