What is biochar?
Biochar is charcoal made from organic material in a low oxygen burn. Unlike ash, it keeps a stable carbon structure that can hold nutrients and moisture in the soil.
When charged with compost tea, worm juice, or diluted nutrients before use, it becomes a habitat for soil life rather than a dry, empty material.
I like using biochar in veggie beds, fruiting zones, and new soil mixes where moisture retention and microbial activity need a boost.
It is not a complete fertilizer by itself, but as part of compost systems it can noticeably improve resilience in hotter and drier periods.
