The Albrecht Papers: Enter without Knocking

Professor Albrecht was one of the first to see the danger in relying on agri-chemicals instead of soil fertility for healthy crops. This book presents more of Albrechts classic articles. Protein contents of crops have declined as soil fertility has dropped. In this collection of writings, Albrecht explains how the soil-crop system works, the importance of various nutrients, and how soil fertility is linked to crop and animal health and even our own as explained by his "biotic pyramid."
