I would think shredding & getting it back into the dirt would be the best way to use char that and germination of seeds with various fire associated dormancy.
I have pulled up a tuft of the Bermuda grass & will grow some in a pot of the char mix & non char mix as an experiment to get the last vestiges of water before wilting & simulate there experiment..
We went to great lengths to build a giant char maker and we did have success using the biochar. We found the pine/fir shavings very much outperformed hardwoods. There are several studies which came to the same conclusion.
Alas, I was dissatisfied with how long it took to get the fire hot enough to reduce emissions. Later I discovered a much better design which I believe I posted a youtube video of in this forum.
Here is the burner almost emitting clean consumed fumes
and then fully consumed
Here are the shavings we used
