Description

Sodium Ferric Eddha is a highly effective, water-soluble chelated iron complex designed to correct iron deficiencies in plants under high pH conditions. Its core value proposition lies in its exceptional stability across a wide pH range, ensuring bioavailable iron delivery where other supplements fail. This product is essential for agricultural professionals, horticulturists, and manufacturers of high-value fertilizers and nutrient solutions targeting crops like citrus, grapes, and ornamentals in calcareous soils.

Application

• Agricultural Fertilizers: As a key micronutrient component in liquid and granular fertilizers to prevent and treat iron chlorosis in crops.
• Professional Horticulture: For fertigation and foliar application in greenhouse production, nurseries, and hydroponic systems.
• Turf Management: To maintain deep green color and health in golf courses, sports fields, and high-end lawns, especially in alkaline soils.
• Soil Amendment Blends: Incorporated into soil conditioners and specialty blends for high-value agriculture and viticulture.
• Foliar Sprays: Formulated into concentrated solutions for direct, rapid correction of iron deficiency symptoms in plant leaves.
• Research & Development: Used as a standardized iron source in plant nutrition studies and for developing advanced agricultural formulations.

Quality Control

Our Sodium Ferric Eddha is manufactured under strict quality protocols to ensure batch-to-batch consistency and efficacy. Quality is verified through comprehensive testing including assay for iron and chelated iron content, identification of the specific Eddha isomers, and control of moisture and solubility. A Certificate of Analysis (COA) documenting purity, chelation percentage, and key physical parameters is provided with every shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent caking and degradation due to moisture absorption.
