From Kiln to Field: Producing Biochar & Putting It To Work on Farms

Biochar is gaining momentum as a tool for compost and soil health—but not all “char” products are created equal. This session offers an overview of what biochar is, how it differs from high-carbon wood ash and other char materials, and why flame-top kilns are a strong option for farm-scale production.

From there, the session connects production to outcomes: how biochar interacts with compost microbes, decomposition dynamics, and compost recipe design, and where it can add value in compost workflows and finished products.

Ken shares lessons from building acceptance and adoption in Northern California. This sets the stage for a discussion of broader applications, including innovative approaches that incorporate biochar in media for compost filter socks, as well as developments in biodegradable sock material, their pros and cons for replacing poly netting, opening the door to new tools and products that support cleaner organics handling and reduced reliance on plastics.
