Cobalt EDTA (CoNa₂EDTA·2H₂O)

Cobalt EDTA is a pink, water-soluble, and highly stable metal chelate that supplies cobalt (Co) to plants in a readily available form. It contains 12.5% elemental cobalt and is widely used in the formulation of plant nutrition products to prevent and correct cobalt deficiencies in crops. Its high chelation stability ensures effective nutrient delivery through both foliar and fertigation systems.

Chemically known as Cobalt Disodium EDTA, it is suitable for use in micronutrient blends and NPK fertilizer formulations. Its optimal pH range of 6–7.5 in 1% solution makes it compatible with a variety of plant nutrition systems.
