Biochar Intensive
A high-impact, intensive one-day immersion into the science of pyrolysis, kiln fabrication, and the regeneration of soil.
The Science of
Sequestration
Biochar is more than just charcoal. It is a highly porous, recalcitrant form of carbon that provides a permanent home for microbes and a long-term reservoir for nutrients and water.
Cellular Architecture
We examine the honeycomb-like structure of biochar under magnification, understanding how surface area correlates to nutrient retention.
Pyrolysis Dynamics
Learn why temperature matters. We explore the 400°C to 600°C range where cellulose becomes stable carbon.
Fabricating the TLUD
The Top-Lit Updraft kiln is a masterclass in airflow engineering. In this workshop, you don't just learn to use one—you build your own.
Steel Fabrication
Hands-on experience with cutting, drilling, and fitting steel drums to create the combustion chamber.
Airflow Tuning
Aperture sizing and chimney ratios. Master the secondary combustion that makes the kiln smokeless.
Modular Assembly
Creating a portable system that can be deployed anywhere, from the garden to the deep forest.
Nutrient Buffer
Prevents leaching in sandy soils through cation exchange.
Fungal Support
Hyphae integration within the biochar pores.
Charging the
Substrate
Raw biochar is a battery that needs charging. We teach the critical protocols for inoculating your biochar with active biology to avoid temporary nutrient tie-up.
- Brewing compost tea for inoculation
- Mineral balancing for specific soil types
- Indigenous Microorganism (IMO) integration
- Application rates and depth strategies

Join us at the Forest Lab for an intensive day that will change how you see the relationship between fire, soil, and the atmosphere.
Included: Materials, Kiln Steel, On-Site Meals, Digital Library
Apply for the
Intensive
Due to the small group size and safety requirements of kiln construction, we review all applications to ensure everyone gets the attention they need. Scholarships are available for BIPOC farmers and regenerative startups.
