It is a lot of charcoal, for me, I see it as a huge potential for trapping greenhouse gases. The more required, the better is the storage. It is a kind of storage that we can put to active use and benefit. We usually spend a lot of fossil fuels to manufacture fertilizers, and so this method can potentially reduce greenhouse gases two ways. One is that the increased fertilizer efficiency by minimizing leaching will reduce our usage of fertilizers and hence use of fossil fuels, and the other is that the carbon trapped will not go back to the atmosphere anymore, so we have a net entrapment.

It could be expensive, but I am buying charcoal when they are for sale, I add them every year. Mix it with my compost too. I plan to design a yard charcoal maker that can process grass clippings and other yard waste, but have no time so far.
