BioChar Notes from Various
If you’re planning on starting a garden, I heartily endorse Biochar. You just need to make sure it is activated by either combining it with compost, rock dust powder, or my favorite, human urine. The urine is a phenomenal source of nitrogen, potassium, and phosphorus and will bind strongly to the carbon in the Biochar rather than draining away. The nitrogen balances the carbon in the Biochar and serves as food for the microbes, which in turn feed the plant for the long term. A friend of mine did this last year in his garden and his plants produced so many vegetables they almost seemed like mutants.
Wetting the Biochar is also important in order to promote beneficial earthworms. One 2011 study3 found that earthworms tend to avoid dry Biochar, but that wetting the char resulted in “statistically undetectable avoidance.” According to the authors: “[I]nsufficient moisture could be a key factor affecting earthworm behavior in soil amended with dry biochar. To avoid desiccation of invertebrates and enable their beneficial ecosystem services, we recommend wetting biochar either before or immediately after soil application.”
You can certainly add Biochar to existing plants, shrubs, and trees, but ideally it’s best if it’s in the soil prior to planting, so the plants have an ideal form of nutrition early on. If you have a small garden, you might only need a few hundred pounds. Larger landscapes will require more.
