Nature gave up her rare secrets to Dr. Albrecht simply because he was a curious farm boy who liked logic and adventure. Through his extensive experiments with growing plants, soils and their effect on animals, he sustained his theory and observation that a declining soil fertility, due to a lack of organic material, major elements, and trace minerals or a marked imbalance in these nutrients was responsible for poor crops and in turn for pathological conditions in animals fed deficient feeds from soils. These papers addressed to scientists, and especially to farmers who worked with nature are as valid today as when they were first written.
