Eight preparations are at the heart of the biodynamic method. Horn manure, horn silica, yarrow, chamomile, nettle, oak bark, dandelion, and valerian are the used to enhance the health and vitality of the soil. In this deeply insightful book, renowned biodynamic expert Manfred Klett explores the principles behind these preparations. He explores in detail each preparation, discussing their various properties, how their substances are enhanced and transformed through the stages of preparation, and the effect of each preparation on the soil and plants.

Throughout, Klett advocates a holistic approach that views farms and gardens as wholly integrated living organisms, with the preparations playing a key role in the improvement of soil quality and the production of healthy plants.

This is essential reading for biodynamic gardeners and farmers who want to delve more deeply into the origin and theory of the preparations, as well as wanting to thoroughly understand the spiritual principles behind the ways in which they work.

“Klett approaches the subject with a deep appreciation for nature and agriculture, and his thorough knowledge of anthroposophy is evident throughout. This book will provide fertile inspiration for anyone wishing to study the biodynamic preparations in greater depth.” — Bernard Jarman (from his foreword)
