This stimulating book provides a highly practical window into the complex, interdependent relationships between soil, plants, animals, and human beings, including special insight into the fascinating life cycle of healthy soils and the imminent dangers we face should their existence become threatened. Poor agricultural practices are draining our soils of nutrients and microorganisms. Depletion of humus is already described as extreme in some areas. Hennig addresses all components of the soil microorganisms, microbes, soil nutrients, and minerals and explores natural fertilization techniques using compost and rock dust along with their roles in humus formation. Translated from its original German, this book will help farmers everywhere understand humus better.

About the Author:

Erhard Hennig spent more than 50 years as a research assistant with Dr. Gustav Rhode in Berlin. Later, Hennig investigated in the West, wrote books and gave lectures all over the German-speaking countries about the life concealed in the soil, and humus development. Together, with Wolfgang von Haller, he founded the Society for Soil and health in Langenburg in Wuttemberg. This was the first institution to spread the seeds of ecological thought for wide political use. Hennig was also one of the founders of the association.
