This long-out-of-print classic showed that soil fertility was directly linked to human and animal disease. Almost a half-century ago, Andr Voisin had already grasped the importance of the subterranean world. He mapped the elements of the soil and their effects on plants, and ultimately, animal and human life as well. He saw the hidden danger in oversimplified fertilization practices and the use of toxic chemicals that ignore the delicate balance of trace minerals and nutrients in the soil.This is not, however, merely a persuasive testament to the link between soil, human and animal health. It is also essential reading for anyone committed to increasing both the quality and the profitability of their pastures. While grass and livestock farmers will benefit most from the wealth of information on rotation management and fertilization practices, there is much in this book for anyone who makes a living from the earth.

With a volume of meticulously researched information, Voisin issues a call to agricultural scientists, veterinarians, dietitians and intelligent farmers to stand up and acknowledge the responsibilities they bear in the matter of public health. He writes as well to the alarmed consumer of agricultural products, hoping to spread the knowledge of the possibilities of protective medicine part of a concerted attempt to remove the causes of ill health, disease and, in particular, cancer.
