General Properties and Industrial Significance:
EDTA FeK refers to a chelated iron compound, where iron (Fe) is bound to EDTA (ethylenediaminetetraacetic acid), and the complex is neutralized with potassium (K⁺) ions. This results in a water-soluble, stable form of iron that is available to plants.
EDTA FeK is a chelated form of iron (Fe³⁺) that uses EDTA to maintain the iron in a soluble and plant-available form.
The potassium (K⁺) ions help balance the charge of the complex, making it stable and allowing it to be absorbed more easily by plants.
Applications:
-
Agriculture:
-
Iron deficiency correction (chlorosis): Used to prevent or treat iron deficiency in plants, particularly in crops like citrus, grapes, vegetables, and ornamentals.
-
Iron is essential for chlorophyll production, photosynthesis, and overall plant growth.
-
It is especially useful in alkaline or calcareous soils, where iron often becomes insoluble and unavailable to plants.
-
Application Methods:
-
Soil application: Applied directly to soil to provide bioavailable iron.
-
Foliar sprays: Applied directly to plant leaves for quick absorption.
-
Fertigation: Applied through irrigation systems.
-
Hydroponics: Used in water-based growing systems to provide iron in a soluble form.
Key Benefits:
-
Bioavailability:
Keeps iron in a form that is easily absorbed by plants. -
Prevents iron lock-up:
In soils with high pH, where iron typically becomes insoluble. -
Potassium (K⁺):
The potassium ions used for charge balance also contribute some nutritional value to plants, making it suitable for plants that need potassium as well.
Summary:
EDTA FeK is a stable, soluble form of iron used to correct iron deficiencies in plants, especially in slightly alkaline to neutral soils. The addition of potassium can be beneficial, particularly for crops requiring both iron and potassium.
