Rick Carr
Farm Director, Rodale Institute
From laboratory research to field applications, Rick Carr has been studying the science and utilization of compost, vermicompost, and liquid compost extracts. In 2012, Rick earned a Master of Science degree in Plant Pathology from Cornell University. Under the advisement of Dr. Eric Nelson, Rick conducted research on understanding the mechanisms associated with vermicompost-mediated disease suppression. His research has contributed to understanding biologically-based disease suppression as well as new information on Pythium aphanidermatum development and pathogenicity. When Rick was not in the lab, he was often doing outreach and education with Master Composters and Gardeners of New York State. Shortly after graduating from Cornell, Rick left the United States for a one-year research opportunity on a large certified organic farm in Argentina. While there he developed a new perspective on how laboratory studies translate to on-farm research and application, which led to a position at Rodale Institute as Compost Production Specialist. As part of the research staff, his projects included managing the Institute’s large-scale composting facility, examining the compost nutrient dynamics from on-farm composting, maximizing the nutrient contribution of pastures for pork production, and exploring novel manure and pasture management strategies to reduce swine parasites in organic pastured pork production. Rick is now the Farm Director of Rodale Institute and directs farming operations at all seven of Rodale Institute campuses across four states. He still manages “his” compost yard at Rodale Institute.
