The Foundations and Principles of Biodynamic Preparations

This definitive guide to the biodynamic preparations, written by world-renowned expert Manfred Klett, is essential reading for biodynamic practitioners.

At the heart of the biodynamic method are the eight preparations used to enhance the health and vitality of the soil: horn manure, horn silica, yarrow, chamomile, nettle, oak bark, dandelion and valerian. In this comprehensive book, biodynamic expert Manfred Klett explores the principles that underlie the preparations. He describes each preparation in detail and demonstrates how they are made, how they are used and what effect they have.

Throughout, Klett advocates a holistic approach, which sees farms and gardens as integrated living organisms, with the preparations playing a key role in improving the quality of the soil and producing healthy plants.
