First Attempt at Biochar

I gathered up all the organic matter readily available in the yard and attempted my first round of Biochar. First I dug a pit. I chose a place that had a large patch of Bermuda grass, so the heat might kill the roots. I shoveled the material I had to burn in the pit and lit it and watched it burn. The beginning smoke was dark and thick and turned to a yellowish, which indicates the "sugars" in the material are burning.

 Once the smoke turned thin and blue/gray, then I covered it with soil to allow the embers to smolder and hopefully create "charcoal".
