Wondering what experience folks have had with the use of biochar, and from the ECHO staff, what the latest information is about how biochar is being used to increase the organic life of a soil and improve agricultural productivity and sustainability
Here is an article from Asia Notes (AN), 2011-04-01, with several links to Biochar related sites:
“Putting Biochar to Use at the Edge: Quality, Soils and Measurement” is an excellent article in Asia Note #35. The information about biochar use on the ground, so to speak, working with resource-limited farmers is pertinent and applicable. I also really appreciate the conversation on how to get useful data using scientific principles in a context with very limited ability to measure things precisely. I was also challenged by the observation that soil maps are available online now. I like to believe that I am a soil geek, but I gave up a long time ago trying to make sense of the scientific soil classifications. Dr. Shafer “shamed” me.
Here is a system for producing charcoal from agricultural waste. The stated goal in the video is to produce charcoal briquettes, but the charcoal produced is also optimal for mixing with soil. We were working with this technique in two or three areas of Haiti, until we discovered the wealth of charcoal powder available at all of the local marketplaces in the spaces where women have been selling charcoal for decades.
