You know, you've got me saying bio char, which is not bone char. Suddenly they are all over the internet. You should be able to buy it locally. Don't you have any farms around you? It should be at a local elevator, or professional landscape supplier. The nuts on the internet are talking about the bones coming from, "Afghanistan, Argentina, India, and Pakistan. The bones are sold to traders in Scotland, Egypt, and Brazil who then sell them back to the U.S. sugar industry." Now ask yourself how much meat do they eat in Afghanistan and Hindu India? And the bones are valuable enough cargo to ship half way around the world to the USA? Get real. Somehow, I think the Chicago stockyards have all the bones we need. You should be able to find it locally.
