Soil salinity is one of the important factors that influence plant physical and biological activities thereby reducing the crop yields. Hence, it is necessary to remove the excess salts from the root zone of the soil for improving crop production. Leaching is one of the important processes to remove salts from the root zone by applying a large amount of freshwater into the field and allowing the water to infiltrate. During infiltration, the excess salts from the root zone are washed away into deep soil layers. This process is effective when it is to be done in soils with low moisture and deep groundwater water tables (Zaman et al. 2018).
