General Properties and Industrial Significance:
EDTA-Zn(NH₄)₂ is a zinc chelate where zinc (Zn²⁺) is bound to EDTA (ethylenediaminetetraacetic acid), and the complex is neutralized with two ammonium (NH₄⁺) ions. It’s a water-soluble, stable form of zinc that is easily absorbed by plants.
The ammonium ions (NH₄⁺) serve primarily to balance charge and sometimes provide a small nitrogen source to the plant.
Applications:
-
Agriculture (Micronutrient Fertilizer):
-
Used to correct zinc deficiencies in crops.
-
Provides zinc in a chelated form, which prevents it from becoming insoluble in the soil, especially in alkaline or calcareous soils.
-
Ideal for use in:
-
Foliar sprays
-
Fertigation systems
-
Hydroponics
-
Soil application
-
Benefits:
-
High bioavailability of zinc to plants.
-
Prevents precipitation or binding with other soil elements.
-
Compatible with most fertilizers and agrochemicals.
-
Works well in slightly acidic to neutral pH soils.
