Autumn is often a time for processing plants that have completed their life cycle or gathering biomass left over after harvest. At this field day, you will learn how this material can be turned into a biological inoculant teaming with microbes to improve soil function and plant health.

The Johnson-Su bioreactor compost is well-suited for situations where there is a lot of material available for composting all at once, such as field cleanup. Created by Dr. David Johnson and his wife Hui-Chun Su, the Johnson-Su Bioreactor is an ideal method of composting in dry, arid climates as it reduces water usage up to six times compared to other composting methods. Little labor is required after the initial set-up as it is a completely no-turn composting process (no need for a tractor or hours of shoveling!). The compost created in these bioreactors is biologically diverse, fungally dominant and has exceptional potential to regenerate poor and degraded soils by providing microbes that establish symbiotic relationships with plants. 

Come join us for a field day where we harvest plant matter from a local park and surrounding area and use it to fill Johnson-Su bioreactors we built this spring. We will also include other feedstocks such as manure and food scraps and discuss how to use and combine different materials for different desired results.

As always, a delicious lunch will be provided! Please RSVP so we know how much food to order.

Friendly dogs welcome
