Johnson-Su Composting Bioreactors cultivate tremendously beneficial soil microbes, but for the microbes to thrive, the systems must be kept from freezing. At this free workshop, learn and practice approaches for setting up a freeze-resistant Johnson-Su Composting Bioreactor, suitable for the winter climate in northern New Mexico. The event is followed by a free meal for participants. IN-PERSON EVENT at Synergia Ranch, 26 Synergia Road
