Nice to hear from you and your interesting question.
I am sure there is value in biochar and in fact I have been given some charcoal burners’ finings to experiment with. But there may be snags too and I also read a high powered article in a sadly-obscure journal (Mother Earth of the Soil Association) whose author, Dr Charles Merfield, put forward many reasons to be cautious.I suspect biochar has a place in farming more than in gardening – but one could perhaps try a small area to see what happens.
