WebApr 13, 2024 · 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 … WebJun 23, 2024 · Nearly all bacteria utilized aluminum phosphate, however fewer could subsist on iron phosphate (FePO 4) or phytate. Microorganisms isolated from phytic acid were also most effective at solubilizing FePO 4, suggesting that phytate solubilization may be linked to the ability to solubilize Fe.
WebSep 1, 2024 · Limitation of rice growth by low phosphorus (P) availability is a widespread problem in tropical and subtropical soils because of the high content of iron (Fe) … WebJan 9, 2024 · It has long been believed that soil microbial activity in tropical forest ecosystems is limited by phosphorus (P) rather than nitrogen (N) availability. In this study, we reviewed the methods used to determine the limiting nutrients and evaluated the validity of the widespread P-limitation hypothesis in tropical forest soils.
