With this English translation of the original German edition, the beginning and intermediate biodynamic gardener and farmer have an excellent, practical resource for learning how to produce the biodynamic spray and compost preparations. The reader will learn about production of the various preparations (501-508), guidelines for the preparation sheaths, how to process and store, how much is needed on the farm, required amounts, and when to make and use the preparations. This book is a good companion to the second book by the same authors, Biodynamic Sprays and Compost Preparations: Directions for Use.
