Briefing

EDTA-Zn, is a good compounding agent in chemistry.

Detailed

What is EDTA-Zn?

EDTA-Zn, or Ethylenediaminetetraacetic Acid Zinc Disodium Salt, is a fully chelated, high-purity micronutrient fertilizer. In this formulation, a zinc ion (Zn²⁺) is securely bound within a stable, organic EDTA molecule to create a water-soluble complex. This advanced chelation technology effectively “shields” the zinc from antagonistic reactions in the soil, ensuring it remains in a plant-available form regardless of challenging soil conditions, particularly in alkaline (high pH) soils where conventional zinc fertilizers like zinc sulfate fail. It is the premium, reliable solution for preventing and correcting zinc deficiency, directly targeting improved crop growth, yield, and quality.

Core Features

1. Guaranteed Bioavailability in All Soils

· pH-Stable Performance: The powerful EDTA chelate maintains its integrity and keeps zinc soluble and available across a broad soil pH range (approximately 4-10). This makes it uniquely effective in calcareous and high-pH soils where up to 90% of applied inorganic zinc can become immobilized.

· Maximum Nutrient Use Efficiency: Virtually 100% of the zinc in EDTA-Zn is delivered in a plant-accessible form. This results in significantly higher uptake efficiency compared to non-chelated sources, allowing for lower application rates while achieving superior and more consistent results.

High Purity & Crop Safety
· Controlled Impurities: Produced to exacting standards with minimal levels of heavy metals and other contaminants, ensuring safety for both crops and the food chain.

· Safe for Sensitive Applications: The chelated form prevents the release of free zinc ions that can cause root damage (phytotoxicity). This safety profile makes it suitable for seed treatment, seedling establishment, and high-concentration foliar sprays without risk of burn.

Stability & Functionality：

1. Chemical & Handling Stability

· Long Shelf Life & Solution Stability: The chelate is chemically stable in both dry form and concentrated stock solutions when stored correctly, guaranteeing consistent quality and performance. It resists breakdown in irrigation systems, preventing clogging.

· Resists Nutrient Lock-Up: Unlike sulfates, it does not react with phosphates or carbonates in the soil or water to form insoluble compounds, ensuring the zinc reaches the plant roots as intended.

2. Agronomic Functionality

· Vital for Enzyme Systems & Auxin Synthesis: Zinc is a crucial cofactor for numerous enzymes involved in critical processes like carbohydrate metabolism, protein synthesis, and the production of auxins (growth hormones), which regulate stem elongation and leaf expansion.

· Corrects Deficiency, Enhances Performance: Rapidly addresses zinc deficiency symptoms (stunted growth, interveinal chlorosis, “little leaf” syndrome), restoring normal development, improving stress tolerance, and enhancing crop yield and quality (e.g., seed set, fruit size).

Applications & Solutions

1. High pH, Calcareous, and Phosphorus-Rich Soils

Application: Essential in soils where zinc availability is inherently low due to high calcium carbonate or high phosphorus levels, which immobilize inorganic zinc.

Benefit: It is the most effective solution to guarantee zinc uptake in these problematic soils, preventing severe yield loss in corn, rice, and fruit trees.

2. Precision Agriculture & Fertigation

Application: The preferred zinc source for fertigation through drip or sprinkler systems, and for hydroponic/soilless cultivation.

Benefit: Provides a clean, soluble, and non-clogging nutrient source, enabling precise control over zinc delivery for optimized plant nutrition.

3. Foliar Spray for Rapid Correction

Application: Highly effective as a foliar spray (e.g., 0.05%-0.1% solution) at critical growth stages (e.g., pre-flowering, early fruit set) or at the first visual signs of deficiency.

Benefit: Offers the fastest correction method, with nutrients absorbed directly through leaves, quickly reversing deficiency symptoms and supporting critical physiological processes.

4. Seed Treatment & Starter Fertilizers

Application: Used in low concentrations for seed coating or in starter fertilizer solutions applied near the seed at planting.

Benefit: Ensures optimal zinc availability during early seedling establishment, promoting stronger root and shoot development for a healthier, more uniform crop stand.
