Winter phosphorus release from cover crops and linkages with runoff chemistry
Winter phosphorus release from cover crops was compared with runoff concentrations in a field setting.
Water‐extractable phosphorus did not increase after frost in frost‐tolerant species.
Water‐extractable phosphorus increased after frost in frost‐intolerant species.
Surface soils contained a larger pool of available phosphorus than cover crops.
Phosphorus released from cover crops was not reflected in surface or subsurface water.
