Price: Ehrenfried was trained under the tutelage of Rudolf Steiner. He worked in the field of agriculture at a time when farmers on the continent were beginning to recognise soil and crop deterioration, in spite of the mineral fertilisers based on the Liebig Theory. It was Dr Steiner’s feeling of urgency which intensified Dr Pfeiffer’s efforts. This booklet presents one small segment of his knowledge of living plants: how they grow, what they reveal about their surroundings and how their powers may be harnessed. Softcover, 96p.
