Iron for the plant: a remedy for chlorosis

         For the plant – a remedy for chlorosis.
        

      In plant organisms iron is part of the active centers of oxidoreductase enzymes catalase and peroxidase, participates in chlorophyll synthesis, respiration processes, nitrogen fixation, and metabolic reactions.

    The iron content in the plant organism averages 0.02% (by weight).
A gradual increase in iron content in fruits is usually observed during their development, with only a slight decrease in its content occurring in mature fruits.

    In case of iron deficiency (usually manifests only in carbonate or waterlogged soils), chlorosis develops in agricultural crops, especially grapes and fruit trees, due to impaired chlorophyll formation. The leaves lose their green color, then turn white and prematurely fall off.
