Soil Fertility and Nutrient management (1+1)

Formation of saline soils

• Saline soils are formed whenever climate, soil and hydrological conditions favour accumulation of soluble salts in the root zone. Arid and semi-arid regions of low rain fall and high temperature leads to less leaching, more evaporation of water and less transport of soluble salts.
• Irrigation with salt-laden underground water and their indiscriminate use under inadequate drainage creates more salinity problems. Excessive use of chemical fertilizers may also leads to form saline saline soils.
