MarKey® Iron 4.5% EDTA Chelate

Liquid chelated iron 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® Iron 4.5% EDTA Chelate 4-0-0 fertilizer is recommended to prevent and correct iron deficiencies in crops. Soil application is preferred to prevent iron deficiencies; however, it may be used as a foliar spray to correct nutrient deficiencies when soil application is impractical.

  • Contains 4% nitrogen and 4.5% iron
  • 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

Packaging Options
Available in 2.5-gallon jugs, 275-gallon totes or bulk volumes.

Application Details

MarKey® Iron 4.5% EDTA Chelate 4-0-0 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.
Iron Icon
Iron is essential for chlorophyll formation and supporting healthy vegetative growth and efficient photosynthesis. It is critical for oxygen production in the plant. Iron is a mobile nutrient but is not transported from old leaves to new ones, often resulting in deficiencies in older leaves. Iron availability in the soil declines as soil pH increases above 4.
