Agriculture - the base for our life has been affected the most due to chemical farming system. Although, this leads to the maximum production of the crops and the vegetables on one side but hyper toxification of soil and water on the other. We have to minimize such farming system at the earliest and adopt organic farming system for the better future of the generations in the years to come. Sources of various raw substrates and their bio-transformation in to organic compost are some of the major issues for the farming communities. The present book is a key to disclose sources and availability of such raw and bio-degradable substrates which are generated every day and are either thrown out or dumped in to different places causing air, water and soil pollution along with their easy bio-transformation technologies in to organic manure.
