It has long been observed, by farmers, gardeners and botanists alike, that from time to time certain plants seem to affect certain other plants growing their near them -- both favourably and unfavourably. By taking account of these relationships, farmers and gardeners can improve the quality of food and flowers, reduce losses from pests and disease, drought and frost, and enhance both satisfaction and pleasure in their work and financial profit. Years of experimentation by Richard Gregg and subsequently Helen Philbrick and others resulted in this unique reference book. It offers a detailed and comprehensive A-Z of plants and how they affect each other and their surrounding environment, including the soil, insects and birds.

Herbert Koepf was a pioneer of biodynamics in Germany, the USA and in the UK. He was an expert teacher, and drew on his own practical background in farming. This book is a collection of some of Koepf's writings on key aspects of biodynamics. It includes practical guidance on building soil structure, preparing and applying biodynamic sprays, crop rotation, compost and composting methods. He also considers ways of researching the effectiveness of biodynamic methods, and measuring results. This is an invaluable guide for anyone working with biodynamic methods, offering Koepf's unique insights and wisdom on practical issues. This overview of Koepf's work is a newly-edited combination of four pamphlets: Compost, Biodynamic Sprays, Three Lectures on Biodynamics, and Research in Biodynamic Agriculture. Published in association with the Biodynamic Association.

Bankrupt farmers, erosion of topsoil, and poor food quality owing to pesticides, hormones, and other additives-these are the well-known realities of the modern crisis in farming. This problem is the outcome of the limited vision of conventional methods and a system that focuses exclusively on quick results and profits. The need for changes is clear, and Koepf provides a vast array of research data and results, as well as many helpful details on animal feeding, crop rotation, diseases, pests, and fertilizing. He shows that the biodynamic method of farming and gardening is the alternative that can turn farming around. Biodynamics is "the oldest alternative agricultural movement in the world." It is based on the concept of the whole farm as a single organism. Its goals are to protect and nurture the soil, improve the quality of food, and organically integrate the farm into the environment as a whole. This is an essential reference for all farmers who are unsatisfied with conventional methods and for gardeners who wish to improve the quality of life around them as well as the food they serve their families.
