Project Information


This research project addressed the need to dispose mushroom spent media by developing a potting mix which also opened the opportunity to diversify our income stream. The results demonstrated that the HE potting mix that we developed promoted higher percentage of germination of stronger and greener seedlings. Evaluations by independent parties who tested in their nursery or garden reaffirmed our findings. The open house gatherings made possible a hands-on experience and provided opportunities for questions and answers and input for future end users. The newspaper article prompted telephone calls from people interested in using the compost and mix for their nurseries. It was interesting to learn of the interest to buy our compost and mix from a company who offers designs and establishes green roofs. This also stirred interest from our mushrooms clients some of whom want to buy compost too. The link and collaboration with the University and the Department of Agriculture personnel were also strengthen. The SARE producer grant made this research and outreach activities possible and contributed to expand knowledge and awareness on sustainable agriculture practices.
