Re: Terra Preta
Welcome, Philip! Please let us know how your tomatoes do.
I have another question about terra preta. Would it be possible to coat the inner pores of charcoal with non-wood bio-oil condensates, such as from other vegetable or plant sources, to similarly favor the growth of microbes?
The reason I ask this is that now I use mostly spent coffee grounds and occasionally the swill from leftover soymilk bottles to fertilize my potted plants in the terra preta. When I brew coffee, I can see there are oils on top of the brew, and I imagine there still must be some, and many other chemicals, present in the spent grounds. Also, soymilk has quite a lot of plant oils. I wonder if these might be absorbed by the terra preta as decomposition takes place. Perhaps in agricultural settings waste vegetable or plant "juice," if rich in oils, could be used as a "bio-oil inoculant" for the terra preta?
