Manganese deficiency (plant) soil pH. Two materials commonly used for lowering the soil pH are aluminum sulfate and sulfur. Aluminum sulfate will change the soil pH instantly because the aluminum produces the acidity as soon as it dissolves in the soil. Sulfur, however, requires some time for the conversion to sulfuric acid with the aid of soil bacteria. If the soil pH is not a problem and there is no manganese actually in the soil then Foliar feeding for small plants and medicaps for large trees are both common ways for homeowners to get manganese into the plant.

Manganese recovery of the manganese. For further purification, the manganese can then be sent to an electrowinning facility. In 1972 the CIA's Project Azorian, through billionaire Howard Hughes, commissioned the ship "Hughes Glomar Explorer" with the cover story of harvesting manganese nodules from the sea floor. That triggered a rush of activity to collect manganese nodules, which was not actually practical. The real mission of "Hughes Glomar Explorer" was to raise a sunken Soviet submarine, the K-129, with the goal of retrieving Soviet code books. Manganese has no satisfactory substitute in its major applications in metallurgy. In minor applications, (e.g., manganese
