Biodynamic Farming and Gardening: Renewal and Preservation of Soil Fertility by Ehrenfried E. Pfeiffer (Revised 4th ed.)

There have been numerous developments and advancements in biodynamic agricultural methods since Ehrenfried Pfeiffer introduced North Americans to the foundational principles and practices of biodynamics, the basics of which continue to be used today. Thus, although Biodynamic Farming and Gardening was first published in 1938, it remains a foundational text for anyone who is or plans to become a serious biodynamic farmer or gardener.

Dr. Ehrenfried E. Pfeiffer (1899-1961) was born in Munich. He worked closely with Rudolf Steiner to test and document many of the effects of biodynamic practices. Pfeiffer visited the U.S. several times during the 1930s, and was awarded a doctorate for his groundbreaking theory of Sensitive Crystallization Processes as a blood test for detecting cancer. In 1940, he immigrated to the U.S., where he pioneered biodynamic agriculture and helped establish the Biodynamic Farming & Gardening Association. He died in Spring Valley, New York.
