My son asked me if I used bio-char in my garden. I haven't, but I would like to learn more about that possibility. There is lots for sale on Amazon, but I am finding mixed reviews on-line as to the efficacy and advisability of using it. What is the research based answer to using bio-char?
Tillamook County Oregon biochar
Here is an information bulletin from Washington State University Extension regarding using bio char in the home garden.
It outlines benefits, drawbacks, and best uses if you want to test its effects in your home garden.
