Effects of soil salinity Salts in the soil water solution can reduce evapotranspiration by making soil water less "available" for plant root extraction. Salts have an affinity for water and hence additional force is required for the crop to extract water from a saline soil. The presence of salts in the soil water solution reduces the total potential energy of the soil water solution. In addition, some salts cause toxic effects in plants and can …

…crops are presented in Table I. To calculate the yield of a crop, insert the appropriate values for t and s from Table I and the ECe of the crop root zone into equation 1. For example, if the soil has an average ECe of 3.7 dS/m and corn was grown for grain, the crop yield relative to nonsaline conditions would be Yr = 100 - 12 (3.7 - 1.7). From this, we can calculate the expected crop yield ------------------------------------------------------------------------ **Bibliography**
