(2010) - Phosphate desorption in luvisols and solonetz from a Mediterranean region. In International Phosphorus Workshop, 6, Sevilha, 2010. Poster.http://hdl.handle.net/10400.11/539Poster apresentado no 6th International Phosphorus Workshop, que decorreu em Sevilha de 27 de Setembro a 1 de Outubro de 2010.Transfer of P from soil to water is controlled by the P retention capacity in the solid phase, namely by the equilibrium between adsorbed and precipitated forms. Desorption of P and/or phosphate dissolution govern the amount of P released into drainage water, runoff or freshwater. Soil P evaluated by Olsen method showed a strong correlation with the capacity of soil to desorb P and, within certain limits, to the transfer of P to water. This transfer of P relates to losses that occur either in surface horizons, or in subsurface horizons (to drainage water, to runoff or by soil erosion to freshwater).engPhosphorusDesorptionOlsen methodconference object
