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.

FAQ
Q1: Why choose EDTA-Cu over much cheaper Copper Sulfate?
A: Cost-effectiveness is about results, not just price per kg. Copper Sulfate becomes ineffective in neutral to alkaline soils, wasting money and risking crop loss. EDTA-Cu works reliably in ALL soil types, ensures high uptake, and requires lower application rates. For high-value crops or problematic soils, EDTA-Cu delivers a far superior return on investment by guaranteeing the intended agronomic result.
Q2: Can EDTA-Cu be mixed with phosphate or sulfate fertilizers?
A: In a concentrated stock solution, do NOT mix EDTA-Cu with phosphates (e.g., MAP, MKP) as this will cause insoluble precipitates. For final tank mixes in the field (diluted), it is generally stable. Mixing with sulfates (e.g., magnesium sulfate, potassium sulfate) is usually safe. Always conduct a jar compatibility test before large-scale mixing.
Q3: Is this product suitable for organic farming?
A: No. EDTA is a synthetic chelating agent and is not approved under major organic certification standards (e.g., USDA NOP, EU Organic). For organic production, approved copper sources include copper sulfate (Bordeaux mixture) and copper hydroxide, though their use is often restricted.
