Abstract

Phosphorus is an essential input and often a major constraint for successful crop production in India, as about 98 per cent of the soils have inadequate supply of available phosphorus. However, phosphorus management in the sod is a difficult problem arid it encompasses an array of factors the soil, crop, fertiliser and cropping system, each with a multitude of problems of its own. In this paper various aspects of phosphate management problems in the light of crop removal of the nutrient and its balance- sheet, direct, residual and cumulative effects on crop growth as well as cropping systems have been discussed. Areas of deficiency in relation to research on phosphate, use efficiency have been outlined with suggestions for intensified research for the solution of the several complexities of the problem
