Micronutrient Functions in Plants
- 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.
