Biochar gardening with Adrian Whitehead

Join Adrian Whitehead to discover more about this mysterious and highly beneficial soil additive. What it is, a brief history of its use, why it works, and how to use it to benefit soil fertility at home. Also, take some home to try it out for yourself.

Biochar is the carbon-rich ‘hull’ of a plant that remains when it is burnt by pyrolysis (without oxygen). This has long been used as a soil enhancer to retain water, improve soil biodiversity and enhance available nutrients that can boost plant growth and potentially utilises agricultural wastes.
