EDTA Zn
General Information
EDTA Zn is a white powdered chelated zinc fertilizer with high bioavailability that is more effective than regular inorganic zinc fertilizers. It is currently an effective zinc supplement for treating zinc-deficient conditions like little leaf disease in plants.
Fully water soluble and absorbable, EDTA Zn has excellent solubility, high efficiency, and prolonged duration in providing readily available zinc to crops. It can quickly supply zinc to prevent physiological symptoms caused by zinc deficiency, such as little leaf, rosetting, rice stunted seedlings, corn white bud disease, etc. EDTA Zn enhances photosynthesis, plant growth and development, disease resistance, quality improvement, and yield increase.
In agriculture, EDTA Zn is used as a micronutrient. In fertilizer production, it can be widely used in foliar fertilizers, fertilizer injections, drip irrigation fertilizers, various micronutrient fertilizers, organic fertilizers, and compound fertilizers. It can be applied through foliar spraying, fertilizer injection, drip irrigation, base fertilization, topdressing, and soilless cultivation.

Advantages
1. EDTA chelated zinc can enhance photosynthesis of plants.
2. Zinc can increase the protein content in grains.
3. Application of EDTA chelated zinc can increase the content of ribonucleic acid in the body, thereby promoting plant growth.
4. Plants have different sensitivities to zinc deficiency. For example, corn, rice, buckwheat, soybeans, cotton, tobacco, sunflower, cabbage, celery, spinach, etc. are highly sensitive to zinc deficiency. Apples, citrus, grapes, coffee, etc. are moderately sensitive to zinc deficiency.
5. Zinc is also the precursor of IAA in plants.
