  • Two key factors control phosphorus movement from soil to groundwater

    New insights into how phosphorus leaches into groundwater could help reduce its potential impact on water and the environment, a UF/IFAS scientist says. Phosphorus poses an environmental threat when it travels from soils to open water bodies, including lakes, streams and rivers. When too much phosphorus is applied to soils, the ground cannot hold all of the chemical, said Gurpal Toor, an ...
