Does anybody use Biochar as component of soil mix?
Pretty straight-forward... I've read about some of the benefits of biochar added to poor soils to improve quality, but does anybody here use it as a component of their soil mixes? I have access to large amts. of the stuff and am just getting into biological growing after years of salt-based gardening. What are the benefits/drawbacks? What percentage of the soil mix can biochar comprise? I have bags upon bags of duff from Lazari's Mesquite charcoal and would like to find another use for it. This is unburnt, fine powdery stuff that would mix with soil very well. I assume that if used too much, the soil acidity might be affected, but am not sure.
