SALINATION OF SOILS
Main Article Content
Abstract
Saline soils include soils that contain mineral salts in amounts harmful to plants. Crushing of agricultural crops begins when the amount of salt in the profile exceeds 0.25% of the soil mass. In arid desert and semi-desert zones without deep soil moisture, salt accumulation occurs as a result of their biogenic accumulation, weathering, soil formation, as well as impulse formation (wind passage). it can. In the semi-desert and desert areas, there are favorable conditions for the formation of sodium sulfates and chlorides, gypsum and nitrates. Sometimes soda formation and the formation of soils with a soda type of salinity can occur. Saline soils are divided into low, medium and high salinity, as well as saline, salty, malty. It is 0.25-0.4% in water in slightly saline soils, 0.4-0.7% in medium salinity, and 0.7-0.1% in strong salinity.
