Salt-affected soilsSalt-affected soilsA global concern
reducing agriculturalproductivity
Saline soils have excessivelevels of soluble salts.
It can negatively impact or inhibit plant growth and can be toxic to life.
Sodic soils have a high amount of adsorbed sodium.
It leads to degradation of soil structure and inhibits plant growth.
