Description

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.


Agricultural Applications of Ferrous Sulphate Monohydrate

Correcting Iron Deficiency in Crops

Iron deficiency is a common nutritional problem, especially in alkaline soils where iron becomes less available to plants.

Ferrous sulphate granules are used to help manage:

  • Leaf yellowing (iron chlorosis)
  • Poor chlorophyll production
  • Weak plant growth
  • Reduced crop performance caused by insufficient iron availability

Common application areas include:

  • Field crops
  • Horticultural plants
  • Fruit trees
  • Vegetables
  • Ornamental plants

Industrial Applications

Beyond agriculture, Ferrous Sulphate Monohydrate Granular is used in several industrial sectors.

Water Treatment

Iron sulphate compounds are utilized in water purification processes, including wastewater treatment applications where iron-based chemistry helps manage impurities and improve treatment efficiency.


Fertilizer Manufacturing

The product is an important raw material for:

  • Micronutrient fertilizer production
  • NPK fertilizer blending
  • Soil amendment products
  • Iron-enriched agricultural formulations

Animal Feed Applications

Ferrous sulphate is also used as an iron supplement ingredient in animal nutrition products where controlled iron supplementation is required.


Chemical and Manufacturing Uses

Other applications include:

  • Production of iron-based compounds
  • Pigment manufacturing
  • Mordant applications
  • Industrial chemical processing

Why Choose Granular Ferrous Sulphate Instead of Powder?

Granular ferrous sulphate offers operational advantages for commercial users:

Easier Application

Granules distribute more evenly during mechanical fertilizer spreading.

Lower Dust Levels

The larger particle structure reduces airborne dust compared with fine powder.

Improved Storage

Properly stored granules maintain better physical stability and reduce handling issues.

Suitable for Bulk Operations

The product works well for fertilizer factories, distributors, and agricultural suppliers handling large volumes.


Storage and Handling Recommendations

For maintaining product quality:

  • Store in a cool and dry environment.
  • Protect from moisture and excessive heat.
  • Keep packaging sealed when not in use.
  • Avoid prolonged exposure to humid conditions.

Proper storage helps preserve product flowability and chemical stability.
