The importance of manganese .. Activation of enzymes and the construction of chlorophyll and the necessary process of photosynthesis

1 - works as a factor of oxidation so it prevents the desired retirement of iron within the plant and thus lead to the emergence of iron deficiency.
2 - tonic for many enzymes and is an important factor for the construction of chlorophyll.
3 - necessary for the sole oxygen during the process of photosynthesis.
4 - plays a role in the activation of enzymes responsible for the conversion of nitrates to nitrite and therefore lead to the lack of increased accumulation of nitrates in the tissues of plants.
