Abstract

The importance of organic matter in Agricultural system is well founded. Besides improving the soil physically, chemically and biologically, it serves as a source of readily available plant nutrients to the crop. The organic matter also serves to mobilize the soil native phosphorus and added inorganic phosphorus into readily available forms. Most of the past studies on organic matter and green manure have been made mainly as a soil amendment and as a mobilizing agent of soil phosphorus. In the present study, the result of green manuring of paddy, as a source of organic 'P' in combination with added inorganic 'P' in different proportion is presented.
