Walter Goldstein was introduced to biodynamic farming by Peter Dukich in California in 1972. He then studied together with Herbert Koepf and Jochen Bockemuehl in Europe and completed his Doctorate in agronomy at Washington State University in a project comparing conventional, organic, and biodynamic farming. He worked as research director at Michael Fields Agricultural Institute in Wisconsin for 25 years. His work there involved on-farm research with soil management for organic/biodynamic farmers, soil and root health, and breeding corn. Recently he began a new organization in Wisconsin (the Mandaamin Institute, Inc.) dedicated to developing healthy, sustainable farming. His present efforts emphasize breeding/selecting nutritious corn and wheat varieties for farmers, breeding corn for nutrient efficiency, and promoting breeding for a healthier agriculture.
