2018

Primary purpose of this project was to see if we could combine two farm waste streams: woody debris and animal manure, in order to make valuable composts and organic fertilizers for use on the farm. We worked with eight farms and a large crew of volunteers and advisors to carry out multiple projects and experiments, making and using biochar, over the two-and-a-half year grant period. The project was developed and implemented by the Umpqua Biochar Education Team. UBET is a learning and sharing network of dedicated volunteers based in Douglas County, Oregon.
