One of the leading authorities on biological farming, Zimmer is recognized for improving farming by restoring soils. Arguing that an optimally productive soil contains a balance of inorganic minerals, organic materials and living organisms, he relies less on modern improvements than on ''the things we've learned by improving fertility in a natural, sustainable way over many years.'' This book offers invaluable scientific support for committed organic farmers as well as conventional farmers who'd like to reduce chemical inputs and use natural processes to their advantage. Advancing Biological Farming updates and expands upon Zimmer's classic, The Biological Farmer. Technically precise yet written in friendly language, this book is for everyone who wants a future in bio-logical farming.
