Johnson-Su Bioreactor Construction and Filling Field Day
November 23, 2025 @ 10:00 am - 2:00 pm UTC+0
At this Field Day, you’ll learn how to build and fill a Johnson-Su Bioreactor—a low-maintenance, no-turn composting system designed by Dr. David Johnson and Hui-Chun Su. It’s ideal for dry climates, using up to six times less water than traditional composting and requiring no tractor or heavy equipment. The resulting compost is microbe-rich and helps restore soil health.
Participation is free, and if you’d like to build your own bioreactor, you can purchase a kit at cost ($80 full-scale, $40 half-scale, $20 2’x2′). Payment can be made during registration. If you’re taking a kit home, please bring a truck or large vehicle for transport.
This is a free field day, but participation is capped at 20 people. To save your spot, please preregister. We have limited parking on the farm so we encourage car pooling.
