Yields of Biodynamic Agriculture of Ernst Stegemann (1882-1943): Experimental Circle Data of the First Biodynamic Farmer

Ernst Stegemann (1882–1943) was the first biodynamic farmer. He was an Anthroposophist with a 375 acre (150 hectares) mixed farm at Marienstein, midway between Frankfurt and Hamburg, Germany. Stegemann attended the Agriculture Course at Koberwitz (now Kobierzyce, Poland) in June 1924 at which the New Age philosopher, Dr Rudolf Steiner (1861–1925), laid the historical foundations for biodynamic and organic farming. Stegemann was a founding member of the Experimental Circle of Anthroposophical Farmers and Gardeners which was founded by Steiner during the Koberwitz course. Prior to the Course, Steiner gave Stegemann some preliminary insights on agricultural practice. Steiner’s injunction to the farmers and gardeners of the Experimental Circle was to test his “hints” for a new and then un-named agriculture, to establish what works, and then to publish the results, and thereby bring the ‘era of secrecy’ to a close. Until that point, members of the Circle were to maintain confidentiality of the Course and experiments. The present paper reveals some of the earliest results of putting Steiner’s indications to the test. For Stegemann, over eight years, the annual yield for sugar beet show increases using Biodynamics of up to 26% (compared to the base year of 1923). The annual yield for “cereals” show increases using Biodynamics of up to 42% (compared to the base year of 1923). Stegemann’s longitudinal yield data were presented in June 1931 to Experimental Circle members, under constraints of confidentiality, at his farm at Marienstein (in the then Province of Hanover; now in the German state of Lower Saxony), and now appear unbridled from those constraints of confidentiality.
