Albrecht created a system for balancing nutrients in your soil. He worked with Calcium, Magnesium, Potassium and Sodium trying different ratios to see what worked best. He was trying to create the "ideal soil." His ratio was essentially 68-12-4-2 base saturation or thereabouts. Michael Astera wrote a small book about this named "The Ideal Soil." The book goes beyond the major nutrients and sets target values for micronutrients and discusses trace elements. It is a bit more complicated than this but I hope I have helped.
