Synopsis Application of phosphate fertilizer has been an important factor for improved crop productivity in India leading to Green Revolution. Phosphate Rich Organic Manure (PROM) - a value added product produced by co-composting different organic wastes with high-grade rock phosphate in fine size has become a useful and effective alternative to costly chemical fertilizers. The present volume is a compilation of researchers carried out on different aspects of PROM, during the last couple of years, in different agroclimatic conditions on diverse crops. It is hoped that the outcome of researches contained in this volume will significantly contribute in the so called "Second and Evergreen Revolution" and the PROM technology will prove to be a boon to the industries producing organic waste, such as pressmud, and will provide a most suitable way for the safe and profitable utilization of these wastes.
