Chloride (Cl) is required in small quantities but is very active in plant cells. It acts with potassium to regulate stomatal openings in the leaves, controlling internal water balance, and functions in cation balance and transport. Chloride is effective in suppressing and lessening the effect of fungal infections and can advance maturity of small grains in some soils.
It’s a micronutrient needed only in small amounts, but iron (Fe) plays a critical role in photosynthesis, helping to keep crops green, healthy and thriving.
Iron is involved in chlorophyll development and plays a role in energy transfer, metabolism and respiration. It is also important for the structure and function of proteins and enzymes and can increase nitrogen fixation and use.
