Biodynamic agriculture first originated in central Europe but is now practiced in farms, vineyards and gardens all over the world. At the heart of the biodynamic approach are the eight preparations -- Horn manure, Horn silica, Yarrow, Chamomile, Nettle, Oak bark, Dandelion and Valerian -- which are often produced by local biodynamic practitioners using well-established recipes. But as the biodynamic approach expands across the world, its methods have been increasingly adapted to meet the needs and challenges -- climates, fauna, seasons and regulations -- of different regions around the globe. This fascinating book presents the results of a unique study, carried out by the Agricultural Section at the Goetheanum, Switzerland, into how the biodynamic preparations are used in fifteen countries worldwide, including Egypt, Brazil, New Zealand, India and across Europe. The detailed case studies explore how the preparations are modified to suit their locations, as well as offering an insight into the work of each practitioner and how their understanding has evolved over the years. This book is a valuable reference into the production and application of the preparations around the world and an inspiring endorsement of how biodynamic principles hold true in such varied environments.
