Abstract

A pot culture experiment was conducted on three soils of Tamil Nadu to study the fluctuations of soil phosphorus fractions during paddy growth under flooded conditions. The study showed that the available P (Olsen's method) and aluminium phosphate content were higher on the 15th day after transplantation than at the post-harvest stage in all the three soils. An increase in calcium phosphate content was recorded with increase of time in all the three soils.
