Resumo(s)
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).
