“According to USDA figures, soil with a 4-5% organic matter content can absorb a 4-6 inch rainfall in an hour, while soil with a 1 1/2-2% organic matter content can only absorb 1/2-1 1/2 inch rainfall. Typical U.S. cornbelts soils are down to only 0.5-2.5% organic matter” (Excerpt from the book Foundation of Natural Farming by Harold Willis Ph.D)

“Humus (decomposed organic matter) cannot be produced if the “humus factory” is destroyed (soil life)”(Excerpt from the book Foundation of Natural Farming by Harold Willis Ph.D)
