Do you mean biochar that has already been inoculated, or can you use "fresh from the kiln"?

The biochar will absorb the fertility that tries to leach down from the pile and will create an air break to help the compost pile stay oxygenated. This will also help stop tree roots from coming up. My compost pile sits at the southern edge of my garden clearing surrounded by trees....zero problems with roots. Give it a shot....composting is noticeably better with biochar dispersed throughout the pile as well, btw. Heats up faster and breaks down quicker.

Yes, the new composts I've built this year have all had fresh biochar added to layers when I've been organized in an effort to get it inoculated. Any suggestions as to volume of new biochar vs volume of everything else that you'd recommend?
I've been reading a book recently that is strongly promoting biochar for helping us stabilize Earth's carbon and getting it out of the atmosphere, so I'm looking for an easier way to make it out of waste products that won't hurt my garden. We've got a lot of trees that are being taken over by English Ivy which will eventually kill them, or increase the risk of them coming down in a windstorm. I'm eyeing that Ivy as fair game for making biochar. If only I had a decent set-up to use Himalayan Blackberry without it hurting me, it would get similar treatment!
