Manganese Sulphate



Pack Size




The availability of manganese in soils is greatly effected by pH. Optimum pH is 6.5, which rapidly falls away increasing towards 7, so the first steps to correct this deficiency is to adjust the pH. Manganese sulphate is a chemically produced salt containing 31% manganese, which is soluble in water, and used as a foliar spray at 1oz. to 4 gallons of water. Manganese can also be deficient in sandy soils, which do not have pH problems.

 To correct Manganese deficiency, particularly in acid soils. Especially useful to chrythanthemums which are often deficient in this element.
