Abstract


Rice being the staple diet of a large section of the population, a detailed study of the transformation of nitrogen and phosphorus in submerged paddy soils and of factors which might induce the increase of toxic principles to deleterious levels is bound to be of great importance in the economic use of nitrogen and phosphorus fertilisers under varying soil conditions. Although benefits of green manuring have been observed in paddy soils, no systematic attempt has been made in paddy soils of Tamil Nadu to understand the behaviour of rice plant in relation to its peculiar chemical regime, which is totally different from that of normal upland soils. In the present investigation, it was proposed to investigate this aspect in detail.
