Phosphorus nonpoint source pollution from soil to water is a growing problem, causing water eutrophication. Using amendment materials to retain phosphorus in soil is a promising strategy for environmental restoration and pollution management. This study reviews the strategies of managing phosphorus nonpoint pollution, including the forms and accumulation of phosphorus in soil, loss of phosphorus from soil to water, and the use of amendment materials to mitigate phosphorus pollution. Environmental risks of phosphorus retention in soil and water conditions are also investigated. This review enhances understanding of phosphorus nonpoint source pollution and provides innovative perspectives for controlling water eutrophication through the application of amendment materials.
Phosphorus (P) nonpoint source pollution from soil to water is increasing dramatically, leading to the eutrophication of water bodies. Using amendment materials for P retention in soil is a promising strategy for environmental restoration and nonpoint source pollution management. This strategy has attracted significant attention because of its highly effective P retention. This study reviews management strategies of P nonpoint pollution from soil to water, including the basic P forms and accumulation situation in soil and P loss from soil to water. Recent advances in the use of amendment materials, such as inorganic, organic, and composite amendment materials, to mitigate P pollution from soil to water have also been summarized. Environmental risks of reloss of P retention in soil with different soil properties and water conditions have also been investigated. This review improves the understanding of P nonpoint source pollution from soil to water, providing an innovative perspective for the large-scale application of amendment materials to control water eutrophication.
