If you are an organic grower and use manure and compost, you might be interested in spending a few minutes to participate this survey conducted by University of California-Davis, The Organic Center and Organic Trade Association. The purpose of the survey is to characterize the use of manure and compost based soil amendments. Results from the survey will be used to study the use of untreated manure and compost in organic agriculture and the impacts of those practices on food safety.
