Briefing

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

Detailed

What is EDTA-Cu?

EDTA-Cu, or Ethylenediaminetetraacetic Acid Copper Disodium Salt, is a high-purity, fully chelated micronutrient fertilizer. It consists of a copper ion (Cu²⁺) bound within a stable organic EDTA molecule, forming a water-soluble complex that protects the nutrient from being locked up in the soil. This formulation ensures that copper remains readily available for plant uptake even in challenging soil conditions, such as alkaline (high pH) soils where traditional copper sources become ineffective. It is the go-to solution for reliably preventing and correcting copper deficiency in a wide range of high-value crops.

Core Features

1. Unmatched Stability & Bioavailability

· pH-Stable Chelation: The EDTA ligand forms an exceptionally strong bond with copper, maintaining its integrity and solubility across a wide soil pH range (approximately pH 4-9), unlike inorganic sulfates which precipitate in alkaline conditions.

· Superior Nutrient Efficiency: Nearly 100% of the applied copper is in a plant-available form. This maximizes uptake efficiency, allowing for lower application rates compared to non-chelated sources while delivering more reliable results.

High Purity & Crop Safety

· Controlled Heavy Metals: Manufactured to stringent purity standards, ensuring minimal levels of undesirable heavy metal impurities, which is critical for food safety and sensitive crops.

· Non-Phytotoxic & Safe: The chelated form prevents the free copper ions that can cause root burn or toxicity, making it safe for seed treatment, seedling application, and fertigation even at recommended concentrations.

Stability & Functionality：

1. Chemical & Application Stability

· Exceptional Shelf Life: The chelate is chemically stable in its dry form and in concentrated stock solutions when stored properly, guaranteeing consistent performance over time.

· Stability in Irrigation Systems: Does not precipitate or react with bicarbonates commonly found in irrigation water, preventing clogging of drippers and ensuring uniform nutrient delivery.

2. Agronomic Functionality

· Essential Enzyme Cofactor: Copper is a vital component of numerous plant enzymes involved in photosynthesis, respiration, lignin synthesis (for stem strength), and disease resistance.

· Corrects & Prevents Deficiency: Rapidly addresses visual symptoms like stunted growth, leaf chlorosis (yellowing), and "die-back" of young shoots in sensitive crops, restoring normal plant metabolism and development.

Applications & Solutions

1. High pH & Calcareous Soils

Application: Essential for crops grown in alkaline or calcareous soils (pH >7.5), where standard copper sulfate is rendered unavailable.

Benefit: It is the only effective way to deliver plant-available copper in these conditions, preventing yield and quality losses in cereals, fruits, and vegetables.

2. Greenhouse & Hydroponic Systems

Application: A standard component in nutrient recipes for soilless cultivation (e.g., NFT, rockwool) and greenhouse fertigation.

Benefit: Provides a precise, reliable, and non-clogging source of copper that is essential for balanced plant nutrition in controlled environments.

3. Copper-Demanding Field & Orchard Crops

Application: Targeted application for cereals (wheat, barley), citrus, stone fruits, and vegetables known for their high copper requirements or susceptibility to deficiency.

Benefit: Ensures optimal enzyme function, improving grain fill, fruit set, flavor, and overall plant vitality and resistance.

4. Foliar Spray for Quick Correction

Application: Used as a highly effective foliar spray (e.g., 0.05%-0.1% solution) at the first signs of copper deficiency or during critical growth stages.

Benefit: Provides the fastest possible correction, bypassing soil interactions entirely, to quickly restore crop health and salvage yield potential.
