Evaluation of phosphorus available in two prairie wetlands: Discharge versus recharge soils

Abstract

In two prairie wetlands, mean available phosphate was six times greater at 0-15 cm in Ca-depleted recharge soil (57.3 mg kg-1) versus Ca-rich discharge soil (13.0 mg kg-1) highlighting the importance of wetland chemistry when characterizing P availability and nutrient loss potentials of prairie wetland soils.
