EDTA MnNa2

General Properties and Industrial Significance:

EDTA-MnNa₂ is a manganese chelate, where manganese (Mn²⁺) is bound to EDTA (ethylenediaminetetraacetic acid) and stabilized with two sodium (Na⁺) ions. It is a water-soluble, stable source of manganese, primarily used in agriculture.
It typically contains around 12–13% elemental manganese.

Applications:

• Agriculture (Micronutrient Fertilizer):

1. Used to correct manganese deficiency in crops like cereals, legumes, fruits, and vegetables.

2. Manganese is essential for:

   • Photosynthesis (especially in chloroplast formation)

   • Nitrogen metabolism

   • Enzyme activation

3. The EDTA chelation keeps manganese available to plants, especially in neutral to slightly alkaline soils where unchelated manganese would become insoluble.

4. Commonly applied via:

   • Foliar spray

   • Soil application

   • Fertigation

   • Hydroponic systems

Key Benefits:

• Highly bioavailable and fast-acting.

• Remains soluble across a broad pH range (up to ~7.5).

• Reduces the risk of manganese precipitating or binding with other nutrients in the soil.
