Manganese sulfate monohydrate (MnSO₄·H₂O) is a pale pink, water-soluble inorganic manganese salt widely used in fertilizers, animal nutrition and industrial applications. With a manganese content of approximately 31%, it provides an efficient source of manganese, an essential micronutrient involved in plant photosynthesis, enzyme activation, animal metabolism and the production of manganese-based compounds.

Manganese fertilizers are not interchangeable. Their efficiency depends on manganese content, solubility, soil pH, application method and crop value.

The global fertilizer market showed a clear divergence this week. Nitrogen fertilizer prices declined sharply, while phosphate fertilizers continued to strengthen under firm cost support from sulfur feedstocks. India has entered the fertilizer stocking period for the Kharif monsoon season. At the same time, soaring costs for water-soluble fertilizers and phosphoric acid are placing considerable pressure on industry margins.
