Free Johnson-Su workshop in Northfield! Tuesday 10/21 @ 1pm
/Join us to learn how to make and manage a Johnson-Su composting system—a static, no-turn composting method developed by molecular biologist Dr. David Johnson and his wife, Hui-Chun Su. This innovative approach is designed to produce a fungal-dominant, microbially diverse compost that supports healthier soils and stronger crops.
This free, hands-on workshop will begin with a short conversation about different composting methods, followed by Agroecologist Juan Alvez of UVM Extension, who will share insights into the “what, why, and how” behind Johnson-Su composting. Then we’ll roll up our sleeves and build and fill a Johnson-Su system together.
When: Tuesday, October 21st 1-3pm
Where: Green Mountain Girls Farm, 923 Loop Rd, Northfield, VT
Why Johnson-Su?
The Johnson-Su method isn’t about adding nutrients directly to soil—it’s about inoculating soil with a diverse community of beneficial microbes. These microbes enhance soil health, improve water retention, and boost plant growth and crop yields. Mature compost can be used as a soil amendment, applied as a seed coating, or diluted into a microbial extract for foliar or soil applications.
Organized by the Composting Association of Vermont and Vermont Healthy Soils Coalition, this free workshop is open to farmers, master gardeners, home and community composters, educators, and soil health enthusiasts. Come learn, build, and see what this composting approach can do!
Regenerative refreshments will fortify participants.
The workshop is free and open to all. Registration is encouraged.
