Phosphogypsum Application Improves the Physical Properties of Salt-Affected Soils

Abstract

Salinity presents a major challenge to food security, especially in arid and semi-arid regions. It negatively affects soil chemical and physical properties and ultimately crop yields. The use of phosphogypsum as an affordable amendment is a sustainable approach to overcome the effects of soil salinity. This research demonstrates phosphogypsum’s beneficial impacts on the physical properties of salt-affected soils including improved water aggregate stability, water retention capacity, total porosity, and bulk density.
