Abstract
This study was designed to evaluate the effects of different percentages of phosphogypsum (PG) on the physical properties and erodibility in sandy soil of south Tunisia. Our results show that the physical properties of sandy soil were greatly improved with the addition of different percentages of phosphogypsum which strengthened the water holding capacity, and higher particulate matter content. Also, the PG amendment reduced the erodibility of the soil compared to the original sandy soil. The erodibility K values achieve 1.44% in 40% PG compared to 0.10% in untreated soil (U). In conclusion, our results demonstrate that different percentages of PG are effective to improve the quality of the sandy soil, including the improvements of the soil structure, nutrients, and anti-erosion ability. Our findings provide important implications for the soil improvement in the farmland of South Tunisia.
