There has been some interesting research done to try and mimic the very black
and fertile soil (tierra prieta ?) in certain areas of tropical south
america. Apparently this soil is man made in the archaeological past and the
black was from charcoal. The study was a comparison between charcoal mixed
with existing soil, charcoal mixed with existing soil and compost, and
compost mixed with existing soil. The one that did the best was the
charcoal, compost, existing soil, mix. I wonder if the charcoal somehow is
able to improve the cation exchange rate and help hold the nutrients in the
soil that would be otherwise washed away. If I were having a hard time with
sandy soil especially where organic matter breaks down quickly I would think
this was worth a try.
