Iron Lignosulfonate is a premium-grade organic trace element fertilizer and chelating agent designed for highly efficient iron delivery in agriculture and agronomy. With a high concentration of lignosulfonate and organic matter, it enhances nutrient uptake, improves soil conditioning, and provides an effective solution for iron deficiency (chlorosis) in crops.

Primary Applications & Usage
This product is engineered for high-performance agriculture, particularly in regions with alkaline or calcareous soils where iron availability is naturally low.
- Prevention & Correction of Iron Chlorosis: Acts as a highly effective organic chelating agent to treat iron deficiency (leaf yellowing) in fruit trees, vineyards, vegetables, and field crops, restoring healthy chlorophyll production.
- Fertigation & Foliar Spray: Thanks to its exceptionally low water-insoluble matter (0.04%), it is ideal for modern irrigation systems, including drip irrigation and foliar spraying, without clogging nozzles.
- Soil Conditioning & Remediation: The high organic matter content (26.6%) and lignosulfonate base stimulate beneficial microbial activity, improve soil aeration, and enhance overall soil structure.
- Fertilizer Blending: Can be seamlessly integrated into complex NPK formulations or liquid fertilizers to create customized, broad-spectrum plant nutrition products.
Storage & Handling
- This product is hygroscopic.
- It should be stored in a cool, dry place away from direct sunlight.
- If the packaging is opened and the product is not completely used, it must be kept tightly sealed to prevent moisture absorption.
Routine Package
- Standard Packaging: The product is typically provided in 25 kg PP/PE woven bags with an inner plastic liner to protect against moisture.
