in the earth’s crust, manganese compounds are in abundance after iron. The lower the pH of the soil, the higher the solubility of this element. The role of this element in electron transfer reactions is the stage of photosynthesis and chlorophyll production and most of the manganese is stored in the leaves and stems of plants.
Plants have different sensitivities to manganese deficiency, for example potatoes, cereals and fruit trees are most sensitive to manganese deficiency. But cotton is the least sensitive to manganese deficiency.
Symptoms of manganese deficiency are first seen in the young tissues of the plant, and in cereals, brown spots appear on the leaf margins. In citrus, manganese deficiency is light green at the margins of young leaves, but the veins remain dark green.
Manganese is a trace element. It plays an essential role in respiration and activates enzymes such as nitrite reductase, which is involved in nitrogen metabolism. Manganese is adsorbed in the soil as the divalent cation Mn+2. In soils with high lime content, the amount of manganese available is low.
The most common manganese fertilizer is manganese sulfate with 16 or 22 % manganese. This fertilizer can be used in both acidic and alkaline soils.
Industrial:
Manganese sulfate is used in the chemical industry to extract zinc from soil. Manganese can be adsorbed in the soil as a divalent cation, the lack of which also causes yellowing of the veins and stunted growth of the branches. The appearance of manganese sulfate chemical fertilizer is white powder.
Manganese sulfate is a product obtained from various industrial oxidations that use manganese dioxide, including the production of hydroquinone and anisaldehyde.
Agriculture:
Micronutrient of agricultural lands and orchards
Production of agricultural fertilizers
