12,89 €
The origin of the organic food and farming movement can be traced back to Rudolpf Steiner's ten day course on agriculture. Because of its inevitable, detrimental effect on human health, Dr. Steiner rejected the recently introduced, artificial nitrogen fertilizers and recommended a return to traditional methods for farm fertility along with ways to enhance them. This abridged version of his agriculture course in everyday language simplifies biodynamics for beginners.
