ZINC

Although Zn is required in small amounts, high yields are impossible without it.

Protein Synthesis and Growth Regulation

Protein synthesis and growth regulation require Zn. Reduced hormone production due to a Zn-deficient plant will cause the shortening of internodes and stunted leaf growth.

Deficiency Symptoms

Zinc is much less mobile within the plant, so deficiency symptoms first appear on the younger leaves.

Metabolic Reactions

Zinc aids synthesis of plant-growth substances and enzyme systems, and is essential for promoting certain metabolic reactions, which are particularly critical in the early growth stages.

Zinc deficiency symptoms

Symptoms of deficiency can vary across crop species, but similarities exist for how nutrient insufficiency impacts plant tissue color and appearance. Nutrient deficiencies are commonly associated with the physical location on the plant (i.e., whether the symptoms are primarily observed on older versus newly formed plant tissue), but these symptoms can spread as the severity of the deficiency progresses.
