Seedbuzz Exclusive: Soil Salinity


Increased concentration of soluble salts in soil and water salinity is referred to as Salinization. It is a foremost task to Agricultural scientists to solve this challenge with respect to the agricultural sector.

Much research has been conducted in the area of relative resistance of plants to salinity. Salt content is a major factor in determining the soils chemical quality along with soil reaction, charge properties and nutrient reserves.

For optimal progress of photosynthetic Mechanism and biochemical processes of plants, ample amount of soil salinity is required, but this would lead to environmental problems such as radical changes in the physical and chemical properties of the soil, effecting the overall productivity of soil and growth of plants.

In spite of natural existence for soil salinity being in attendance, the human intrusion disturbs the natural ecosystem and changes the hydrology of the land, which results in transfer of these salts into the rivers and onto the land at an accelerated pace.

Managing the salinity requires striking a balance between the amount of water entering the field and the amount of water exiting the field. They are correspondingly termed as Recharge and Discharge.

Major research is still underway on the process of revegetation of recharge lands and Salinization defiant plant varieties.
