The present book "Sustainable Agriculture through Organic Composts: Recent Advances in Composting Methodologies" covers a selective and brief account of the salient approaches on composting methodology. A broad distinction as 'Traditional' and 'Rapid'composting practices has been made, based mainly on the considerations of the practices being adopted as a convention; and the recent introductions for expediting the process, involving individual or combined application of treatments like shredding and frequent turning, mineral nitrogen compounds, effective microorganisms, use of worms, cellulolytic organisms, forced aeration, forced aeration and mechanical turnings and so on. Hopefully, the technical information contained herein will prove useful to students, teachers, scientists and of course to the farmer community, more specifically, who are practicing organic farming.
