This pamphlet discusses the increased levels of nitrate in water supplies, animal feeds and food, and the impact it is having on our environment as a whole. The two main sources of excessive nitrates in our ecosystems are chemical nitrogen fertilizers, and effluent from residential areas. In this informative booklet, Dr Koepf assesses the specific problems facing farmers and gardeners.
About the Author
Herbert Hans Koepf(1914-2007) was a hands-on farmer in Germany who went on to receive a PhD in agriculture, specialising in soil science. In 1962, after the death of Ehrenfried Pfeiffer with whom Koepf had worked closely, he became director of Pfeiffer’s biodynamic research laboratory in Spring Valley, New York. Then in 1970 he moved to Emerson College in the UK, running the biodynamic agriculture course every year until 1990. He was also head of the Agriculture Department at the Goetheanum in Switzerland.
