Most micronutrients are part of the enzyme systems of plants.
Micronutrients play important roles in redox reactions
Micronutrients play important roles in photosynthesis.
Micronutrients are important in reactions such as N fixation, Protein synthesis.
It is Complex to identify all roles. The identified roles:
Cl is primarily involved in osmotic and cation neutralization.
Cu, Fe, and Mo are active in the oxidation-reduction reactions in plants, which are essential for photosynthesis, and other metabolic processes.
Fe involved in chlorophyll synthesis and can be deficient in turfgrass, especially if soil is alkaline. Any condition that restricts root growth can also cause iron deficiency, for example, compaction.
Zn and Mn are essential for certain N transformations in plants.
Ni is essential for the function of the urease enzyme.
Mo is essential for symbiotic fixation of N.
B is involved in cell division, and seed formation.
Co is essential for the growth of symbiotic microorganisms, such as rhizobia, free-living N-fixing bacteria.
