Soil chemical degradation is undesirable changes in soil chemical properties such as pH, size and composition of cation exchange complex, contents of organic matter, mineral nutrients, and soluble salts. These changes that severely deteriorate the chemical fertility of soils may result in soil acidity, alkalinity, salinity, sodicity, and depletion of soil organic matter and plant nutrients, and lead to a decrease in soil productivity.
