Micro Nutrients / Trace Elements These are required in small quantities by the plant, but they are still essential for plant health and production. The trace elements are Copper (Cu), Iron (Fe), Manganese (Mn), Molybdenum (Mo) and Zinc (Zn) and without them plants will exhibit a variety of deficiency symptoms.
Sodium molybdate, Na2MoO4, is useful as a source of molybdenum.
The agricultural industry uses large quantities of sodium molybdate as fertilizer, particularly on vegetables such as broccoli and cauliflower. It is also fed to some cattle to help treat copper deficiencies.
