Ferrous Sulphate Monohydrate Granular – High-Efficiency Iron Fertilizer and Industrial Grade Iron Compound
Ferrous Sulphate Monohydrate Granular (FeSO₄·H₂O) is a highly concentrated iron-based compound widely used in agriculture, fertilizer manufacturing, animal nutrition, water treatment, and various industrial applications.
With a high iron concentration of approximately 30% elemental iron, this granular material provides an efficient source of ferrous iron (Fe²⁺), helping correct iron deficiencies while supporting healthier plant growth and improved nutrient availability.
Unlike traditional powdered forms, granular ferrous sulphate offers improved handling characteristics, reduced dust formation, better flowability, and easier application in large-scale agricultural operations.
What Is Ferrous Sulphate Monohydrate Granular?
Ferrous Sulphate Monohydrate is an inorganic iron salt containing one molecule of crystallized water. Its chemical formula is: FeSO₄·H₂O
The product belongs to the ferrous sulphate family and contains a higher iron percentage compared with hydrated forms such as ferrous sulphate heptahydrate because of its lower moisture content.

Key Benefits of Ferrous Sulphate Monohydrate Granules
1. Excellent Source of Plant-Available Iron
Iron plays an essential role in chlorophyll formation, photosynthesis, enzyme activity, and plant metabolism. When crops experience iron deficiency, plants may develop yellow leaves, poor growth, and reduced productivity.
Ferrous sulphate monohydrate supplies soluble iron that helps restore iron levels in soil and supports stronger crop development.
2. High Iron Concentration for Efficient Application
With around 30% elemental iron content, ferrous sulphate monohydrate provides more iron per unit weight compared with many alternative iron sources.
This makes it suitable for:
- Soil iron correction programs
- Micronutrient fertilizer blends
- Customized fertilizer formulations
- Agricultural nutrient management
3. Better Handling Compared With Powder Forms
The granular structure provides several practical advantages:
- Reduced dust generation
- Easier transportation
- Improved storage stability
- Better mechanical spreading performance
- Suitable for fertilizer blending operations
Granular products are commonly preferred for large-scale farming applications where accurate dosing and convenient handling are important.
