Abstract

Soil salinity is a major limiting factor that endangers the capacity of agricultural crops to sustain the growing human population. It is characterized by a high concentration of soluble salts that significantly reduces the yield of most crops. Soils with an electrical conductivity (EC) of the saturation soil extract of more than 4 dS m-1 at 25°C are called saline soils, which are equivalent to approximately 40 mM NaCl and generate an osmotic pressure of approximately 0.2 MPa. Salts generally found in saline soils include chloride and sulfates of Na, Ca, Mg, and K. Calcium and magnesium salts are at a high enough concentration to offset the negative soil effects of sodium salts. The pH of saline soils is generally below 8.5. The normal desired range is 6.0–7.0.
