Hugo Erbe's New Bio-dynamic Preparations

"It may appear, at first sight, presumptuous to wish to add anything to what Rudolf Steiner gave from his comprehensive spiritual insight. However, Steiner never left any doubt that he didnot wish his indications to become hardened dogmas, but that they should rather be seen as laying the foundations for a new type of agriculture and as being open to further development and to modification according to circumstances. We may reasonably presume that he expected his pupils to develop their own personal activity out of the needs of each new situation."Among his many achievements, Hugo Erbe, 1895-1965, developed grains from wild grasses without hybridisation or genetic manipulation. What were his tools? How did he approach the task? Even for those familiar with Bio-dynamic farming and gardening the answers are intriguing.
