The transformation of soil inorganic phosphorus was studied in Dhankar soil at field moisture capacity and waterlogged condition. The amount of reductant soluble-P and residual-P decreased and that of calcium-P, iron-P increased with time under both the conditions. Aluminium-P decreased at field moisture capacity; but Us amount slightly increased under waterlogged condition. Ammonium sulphate, straw, and ammonium sulphate in combination with straw treatments decreased Ca-P content under both the conditions.
