I have assembled the information contained in this web site from years of on-farm experience, very concentrated fieldwork developing PERC, and many hours studying many different University bulletins. Any errors or misconceptions are mine and mine alone. If the reader/visitor to this web site would bring errors to my attention, I would appreciate it and would be happy to discuss said error either on the phone or via email.
