Some things just don't biodegrade well here, and part of it is that we're still perfecting our composting workflow and making sure our heaps don't overdry and die in our arid environment. We're getting better all the time, and it's a learning process. But in the meantime, I've been doing a lot of research on biochar. Most of the USDA fact sheets only talk about using biochar from wood or agricultural "wastes" like cornstalks, straw, etc. However, I know for a fact that in much of South America it's common to burn animal bones, manure, and more.
So, talk to me about biochar! Do you use it? What do you burn? What have your results been? Do you combine it with other soil remediation tactics (compost, compost teas, etc.)?
