In this remarkable series of lectures, delivered in 1924, Rudolf Steiner first laid down the principles of biodynamic agriculture. Each lecture contains fascinating insights into farming, the plant and animal world, the nature of organic chemistry and the influences of the heavenly bodies. The discussions which followed are also recorded, in which Steiner answered questions and engaged in debate with the audience. This edition comes with full editorial notes and appendices, and includes Steiner's own handwritten notes to the series.
