Zinc Sulphate Heptahydrate

Zinc (Zn) is an essential nutrient required in some fertilizer programs for crop production in Minnesota. While some soils are capable of supplying adequate amounts for crop production, addition of zinc fertilizers is needed for others. In Minnesota, Zn may be needed in fertilizer programs for production of corn, sweet corn, and edible beans. Several research projects have focused on the use of this nutrient, and much of the following information is based on the results of that research.

The Role of Zinc in the Plant

The specific role of Zn in growth and development of plants is not known. This nutrient is an important component of various enzymes that are responsible for driving many metabolic reactions in all crops. Growth and development would stop if specific enzymes were not present in plant tissue.

Zinc, however, is needed in very small amounts. Plant uptake of this nutrient is calculated in terms of ounces per acre instead of pounds per acre. Therefore, Zn is classified as a micronutrient.

Deficiency Symptoms

Plants fail to develop normally when they are deficient in Zn and certain characteristic deficiency symptoms will appear. With corn, these symptoms usually appear in the first two or three weeks of the growing season. If the deficiency of Zn is severe, these symptoms may last throughout the entire season.
