ABSTRACT
Salt-affected soils have a detrimental impact on crop productivity all around the world. The extent of soil salinization and/or sodification is determined by the type and quantity of salts, their relative abundance in the soil, their impact on soil pH, and their solubility. Nonetheless, crops grown in salt-affected soils are susceptible to several stresses, the majority of which are osmotic and ion-specific. Crop productivity in salt-affected soils is further limited by nutrient bioavailability and the presence of physical barriers. In addition to examining plant stresses and solutions for reclaiming salt-affected soils, the highlights of plant-based approaches in developing new crop cultivars are discussed.
