Influence of oxalate and soil organic matter on sorption and desorption of phosphate onto a spodic horizon

Phosphate (PO4) availability limits the productivity of pine plantations growing on Spodosols of the southeastern USA. Oxalate has been shown to interact with both the sorption and desorption PO4 onto soil mineral surfaces. In addition, organic matter, a crucial component of many soil surfaces, affe...
