Jack Chambers and his wife Lois own and operate Sonoma Valley Worm Farm in Sonoma, California. Jack has spent a tremendous amount of time and energy developing a truly superior worm casting product for use in the vineyards of Northern California. Because of his efforts, Jack has become a leader, and popular speaker in the vermi-compost industry. By incorporating 1-cup of castings into the soil when planting new grape vines, vine loss during the first year has dropped from 25% to less than 2% and the growth response puts these vines into production a year in advance of non-treated vines. Jack also uses his castings to brew compost tea, used both as a root drench and as a foliar spray to successfully combat powdery mildew. Following construction of my prototype aerated compost bin system in 2001, Jack was my first O2Compost Training Program client. He has also become a very good friend.

Fort Lewis – Tacoma, Washington. In 2006, O2Compost completed an extensive pilot demonstration project in support of the U.S. Army’s goal of zero discharge from military bases. The objective of this project was to evaluate the compost ability of a wide range of organic waste materials, from municipal green waste and food waste materials to horse manure, biosolids and petroleum contaminated soils. This project included extensive training of operations personnel, on-call technical services, and presentations to staff. It has received awards for achieving recycling goals at Fort Lewis and is now considered a best management practice, soon to be implemented at other bases around the country.
