Ideas such as "crop and soil weatherproofing," the "row support system," and the "tillage commandments," exemplify the practicality of the soil/root maintenance program that serves as the foundation for Schriefer's highly-successful "systems approach" farming. Schriefer was a pioneer in developing an awareness of the relation of tillage to soil fertility, focusing on three major soil basics soil aeration, soil water, and soil decay. This book covers such topics as soil chemistry, plant and soil dynamics, above- and below-ground plant management, row support fertilization, zone-tillage, disc-chiseling, and more. He focuses on reducing "yield-limiting factors" such as seed selection, excessive tillage and a dependence on technology.
