Abstract

Use efficiency of applied phosphorus (P) is generally low (20%) and it is usually fixed very quickly, it is being retained in the top layers of the soil leading  to saturation of P fixative sites in the soil. The continuous use of ‘P’ fertilizers resulted in ‘P’ accumulation of same in the top layers of soils. For Eg: The recent study under DAC project at Hyderabad indicated that the soils in 10 districts of A.P was
found to contain soils with high available P to an extent of 66 per cent (Reddy et al., 2013).
