Yeah, just another piece of the puzzle. In the short term, albedo changes are going to make a lot more difference.
Do you know if the biochar degradation would be slower if placed relatively deep (> 2ft) down into soil which won’t be tilled, as could be done for an orchard?
Yes, biochar mostly won’t biodegrade if it’s buried in such a way that it doesn’t get oxygen. However, making biochar costs money, so it’s cheaper to dry biomass and add CaCl2.
