BIOCHAR is being used mainly with focus on Agriculture. Before it reaches the soil ultimately, it can be used for many purposes and in the process its value enhances. The Terrapreta was originally a culture in the Amazon, unless we adapt biochar as as culture or "BIOCHARCULTURE" it will not be sustainably adopted and appreciated by communities. At GEO we are using Biochar for different applications as mentioned in this chart http://www.slideshare.net/saibhaskar/biochar-uses In many countries as part of culture biochar is an important component even today. For details of various applications see BIOCHAR INDIA http://biocharindia.com
