MarKey® Zinc 9% EDTA Chelate

Chelated zinc micronutrient plus nitrogen

MarKey® EDTA Chelate formulations are a broad range of fully chelated solutions that include single trace elements or combinations to prevent and correct crop mineral deficiencies.

MarKey® Zinc 9% EDTA Chelate is a fully chelated solution of Zinc EDTA and is recommended to prevent and correct zinc deficiencies in crops. Soil application is preferred to prevent zinc deficiencies; however, it may be used as a foliar spray to correct nutrient deficiencies when soil application is impractical.

Application Details

MarKey® Zinc 9% EDTA Chelate solution can be applied via soil application through drip, sprinkler or furrow irrigation systems, or in a band or broadcast fertilizer applications. It can also be applied via foliar application.

Nutrient Function

Nitrogen Icon
Nitrogen is the main plant protein component and is needed in large quantities for healthy plant growth. Nitrogen deficiency can lead to root disease, reduced photosynthesis, stunted plants and reduced crop yield, while sufficient nitrogen can increase tolerance to early-season soil diseases.
Zinc Icon
Zinc helps facilitate enzyme function for protein synthesis and carbohydrate metabolism in the plant. It is essential for chloroplast formation and auxin metabolism. Auxins are plant hormones that help regulate growth and development, including cell division and flower initiation. Low zinc levels in the soil can increase vulnerability to root diseases such as phytophthora.
