Is biochar a potential solution?

The first study I found on google seems to suggest that biochar lasts for a pretty long time but also decomposes: https://www.sciencedirect.com/science/article/abs/pii/S00380...

If I'm reading that correctly, they say it should last about 4,000 years which should get us pretty far.

Bluntly, yes it is.
