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 Albrecht’s classic papers. 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".
Each volume is a stand-alone book - you don't need to have the entire set to learn vast amoutns from this master soil scientist.
