Zinc (Zn) is taken up by plants as the divalent Zn⁺² cation. It was one of the first micronutrients recognized as essential for plants and the one most commonly limiting yields. Although Zn is required only 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.
Zinc is much less mobile within the plant, so deficiency symptoms first appear on the younger leaves.
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.
pH to Zinc Ratio
As soil pH increases, zinc availability decreases.
Zinc Deficiency Symptoms
of deficiency can vary across crop species, but similarities exist for how
nutrient insufficiency impacts plant tissue color and appearance.
