| Abstract | ||||
| Phosphogypsum is an environmental concern and an opportunity to encounter soil abiotic stresses under arid conditions. The objective of this review is to present an overview of the literature on phosphogypsum (PG) with an emphasis on its agricultural use in Egypt and worldwide, the chemistry of the substance and environmental potential issues that might arise if its leachates encounter soil environment. Phosphogypsum is produced in large quantities by the phosphate industries and is frequently dumped in open areas or released into aquatic habitats. It has detrimental effects on both the environment and human health. However, phosphogypsum is used in a variety of industries, including agriculture for fertilization and soil amendment, the manufacture of cement and bricks, and road construction. Due to the different quantities of heavy metals and radionuclides present in PG, all these uses raise environmental concerns. The advantages to the phosphate industry and costs to the environment and pollution harm must be considered by policymakers. There are a number of variables that affect the usage of PG in agriculture, including PG composition, soil type, area, crop and environmental restrictions. Therefore, each country should carry out independent study specific to its agroecosystems and agricultural regions. | ||||
