Manganese

Manganese attend in the synthesis processes of amino acids and peptics and in numerous enzymatic reactions, making it important for plant metabolism. Cases of manganese deficiency generally occur in alkaline soils, especially with low temperatures and high rainfall. High concentrations of zinc and iron can also lead to manganese deficiencies. The element is found in good quantities in plants. In the soil it occurs in the form of oxides, carbonates, phosphates and even silicates. It is found bound to organic matter in humic compounds and clayey colloids. Its primary function is linked to the formation of chlorophyll and to chlorophyll photosynthesis, in which manganese functions as an electron carrier, varying its oxidative state. It is also present in various enzymes.
