Gear & Products for BioChar Composting
I've tested dozens of kilns, temperature gauges, and charging methods. Here are the ones I recommend based on real-world use.
🔥 Pyrolysis Kilns
Simple drum kilns, rocket stoves, and commercial biochar makers — compare by output size and fuel type.
Gear🌡️ Temperature Gauges
Infrared thermometers and probe sensors for monitoring pyrolysis temperature zones (200-700°F).
Gear🧪 Charging Supplies
Bokashi bran, compost tea extract, and worm castings for charging biochar before soil application.
Gear🔲 Screening Tools
Sieves and sifters for sizing biochar particles — fine (powder) vs coarse (chunk) for different soil applications.
GearTroubleshooting Common Problems
If your biochar production or soil application is acting up, these are the most common issues and how to fix them.
- → Too much smoke during pyrolysis — temperature too low or feedstock too wet
- → Too much ash in final product — incomplete combustion, check airflow
- → BioChar locking up nutrients in soil — always charge before application

Quick Reference: BioChar Basics
- Pyrolysis temp range:400-700°F (200-370°C) for stable carbon; above 900°F destroys pore structure
- Pore size target:Micro-pores (<2nm) for water retention, macro-pores (>50nm) for air and microbial habitat
- CEC boost:Biochar can increase soil CEC by 10-30% depending on feedstock
- Charging time:Minimum 2 weeks in compost tea or worm castings before soil application
- Carbon sequestration:Biochar remains stable for hundreds to thousands of years — a true carbon sink
