Development of innovative low cost Biochar production technology

Abstract
Biochar is a solid product of thermal decomposition of organic matter at a temperature below 900°C under conditions of oxygen deficit, produced for environmental or agricultural application. The selection of low cost biochar production technology will help to the resource poor farmers for application of such a wonderful soil amendments in their own field. In present study, an attempt has been made to develop an eco-friendly low cost biochar production technology which is very easy, economical and cost effective. Both the drum method (portable kiln) and pit method were very suitable for preparation of biochar and thus these two methods can be recommended to the farming community. The recovery of biochar was more in drum method as compared to pit method.
