Manganese byproducts produced in the course of manufacturing electrolytic manganese dioxide provide a novel manganese fertilizer having a fertilizer response that can operate both instantaneously and slow-release. A manganese fertilizer contains manganese byproducts and has 3 to 20 wt % citric acid-soluble manganese (C--MnO) and 0.5 to 7.0 wt % water-soluble manganese (W--MnO).
This invention is for a method and/or solution for treatment of Golden Pine Syndrome. The mixture ideally is a diluted acidic solution that contains 3% to 6% iron (iron sulfate) by weight, 1% to 4% by weight of zinc (zinc sulfate), 0.1 to 4.0% manganese (in the form of manganese sulfate or oxide) and 10% or less of sulfuric acid. The remaining solution by weight is water. This solution is derived from waste pickle liquor disposed from a ferrous galvanizing process.
