The role of hydrogen, carbon, nitrogen, oxygen, phosphorus, potassium, calcium, and magnesium as major nutrients, with iron as a secondary element of importance to plant life, has long been recognized. Recent studies have shown that the micro-nutrients, manganese, copper, boron, zinc, and in specific instances molybdenum, vanadium, and aluminum, play a vital part in increased crop yields. Very low trace amounts of cobalt, along with zinc, copper and manganese, have been shown to be essential to animals.
