Abstract

The study revealed that the phophorus availability in rice soils was intimately connected with moisture regimes.Under flooded conditions the Fe.P.underwent dynamic changes and ultimately influenced the higher concentration of availabile P.While no such realisation was felt in field capacity due to the liberal diffusion of oxygen and low redox conditions.Among the existing methods for the available P.estimation Olsen's and phophate potential methods were found valid when the soils under test were preflooded for 15days.
