Effect of waterlogged conditions on phosphorus sorption and release of 18 soils with contrasting chemical and physical properties was studied in a laboratory experiment.The soils both in aerobic and anaerobic conditions were analyzed for pH,redox potential(Eh),oxalate Fe and the amount of P released measured by means of successively removing soil phosphate using iron oxide-impregnated paper strips.Phosphate sorption isotherms were determined with the standard batch technique for air dried and waterlogged soils.It was shown that after being reduced for 30 days the P sorption capacity,maxim buffering capacity and standard P requirement of most of the soils studied increased while P release from all soils decreased.Our data suggest that the increase in soil oxalate Fe aftrr waterlogging was the main reason responsible for the changes in P sorption and release of the soils studied.
