It's carbon-negative even if you don't count the buried carbon due to it being a powerful fertilizing agent.

- enriquto 5y agoI don't understand your remark. The plants that you are going to fertilize are part of a carbon neutral cycle anyway. It doesn't really matter if there is a big or small amount of them. The buried stuff is going to rot after a few years and release the carbon back. I think the idea is to bury it to "geological" depths, forever isolated to the biosphere. In the last century, we have burned millions of years worth of plant-based carbon sequestration. This was carbon that had been out of the biosphere for millions of years. Now our goal is to remove this carbon out of the biosphere again. I'm skeptical that this can be at all achieved by purely biological means. But burying dead plants a few meters deep, readily accessible to rot, is not likely to make any difference. Otherwise, we are going back to pre-cambrian CO2 levels, which were much higher than today.
