This sounds really interesting. Do you have any reading recommendations (links or books)?

I found these videos very interesting: https://www.youtube.com/watch?v=svNg5w7WY0k&t=5s https://www.youtube.com/watch?v=svNg5w7WY0k&t=5s This is on my to-do list: http://climatechangeacademy.com/courses/carbon-removal/4 http://climatechangeacademy.com/courses/carbon-removal/4 https://bootup.airminers.org/ https://bootup.airminers.org/ I found a lot of information from comments here: https://news.ycombinator.com/item?id=27822694 https://news.ycombinator.com/item?id=27822694

I can also recommend this wikipedia article and its surroundings: https://en.wikipedia.org/wiki/Terra_preta https://en.wikipedia.org/wiki/Terra_preta

As others have noted, the wikipedia entry is a great resource. I was introduced to it on this podcast episode: https://podcasts.apple.com/us/podcast/permaculture-for-the-future/id1494403834?i=1000466849140 https://podcasts.apple.com/us/podcast/permaculture-for-the-f...

Burn, by Albert Bates and Kathleen Draper (2019) - goes into the multitude of ways biochar can be utilised. It's a bit heavy, but in a good (here's the research that backs us up) way. https://www.chelseagreen.com/product/burn/ https://www.chelseagreen.com/product/burn/

Some studies are quite skeptical. For example, https://asi.ucdavis.edu/news/new-study-biochar-helps-yields-only-short-term https://asi.ucdavis.edu/news/new-study-biochar-helps-yields-... https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0075932 https://journals.plos.org/plosone/article?id=10.1371/journal... Some studies even show that biochar soil amendments accelerate the breakdown of humus and release net positive CO2 to the atmosphere: https://onlinelibrary.wiley.com/doi/full/10.1111/gcbb.12376 https://onlinelibrary.wiley.com/doi/full/10.1111/gcbb.12376

  > However, soil CO2 fluxes were suppressed when biochar was added to fertilized soils, indicating that biochar application is unlikely to stimulate CO2 fluxes in the agriculture sector, in which N fertilizer inputs are common. > Our results showed that biochar application increased soil CO2 fluxes by 43.33% in unfertilized soils, but decreased by 8.61% in N-fertilized soils, consistent with the meta-analysis of Liu et al. (2016). The metastudy did go into detail about N2O and CH4 as well in both fertilized and unfertilized soil.
