MarKey® Copper 5% EDTA Chelate

Liquid chelated copper fertilizer

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® Copper 5% EDTA Chelate fertilizer is recommended to prevent and correct crop copper deficiencies. Soil application is preferred to prevent copper deficiencies; however, it may be used as a foliar spray to correct nutrient deficiencies when soil application is impractical.

  • Contains 5% nitrogen and 5% chelated copper
  • Fully chelated micronutrient liquid formulation
  • Provides available micronutrients where they are typically blocked due to high pH or carbonates
  • Makes the trace elements available to the plant, mobile in the soil and stable in the fertilizer formulations
  • Compatible with most fertilizer formulations, especially calcium and phosphate-based products

Application Details

MarKey® Copper 5% EDTA Chelate 5-0-0 fertilizer can be used as a foliar spray or soil-applied micronutrient.

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.
Copper Icon
Copper is essential for photosynthesis and facilitates enzyme production for carbohydrate and protein metabolism. The nutrient influences pollen formation, viability and fertilization, thus affecting fruit set. Low levels of copper in acidic soils can lead to an accelerated uptake of manganese that could be toxic to the plant. Copper sprays can be used to manage bacterial and fungal diseases in fruiting crops.
