Detail Information
What is Ferrous Sulphate Monohydrate Powder?
Ferrous Sulphate Heptahydrate Crystalline Powder (FeSO₄·7H₂O), commonly known as green vitriol or copperas, is a water-soluble iron supplement appearing as bluish-green crystalline powder. With iron content ≥19.5% and sulfur ≥11%, it serves as an essential micronutrient source for agriculture, animal nutrition, and industrial applications. Its fine crystalline structure ensures rapid dissolution and high bioavailability, making it ideal for correcting iron deficiency in plants and animals, as well as functioning as a reducing agent in water treatment and chemical processes.
Core Features & Competitive Advantages
High Purity & Dual Nutrients
• Iron Content ≥19.5%: Provides highly soluble ferrous iron (Fe²⁺) for rapid absorption by plants and animals
• Sulfur Content ≥11%: Supplies essential secondary nutrient for protein synthesis and chlorophyll formation
Optimized Physical Properties
• Fine Crystalline Powder: 80-100 mesh particle size ensures complete dissolution within 2 minutes
• High Solubility: 256 g/100mL at 20°C, leaves no residue in irrigation systems or feed mixtures
Quality & Safety Assurance
• Heavy Metal Control: Pb≤10ppm, As≤5ppm (compliant with EU fertilizer and feed standards)
• Chloride-Free Formula: Safe for chloride-sensitive crops and animal feeding
Stability & Functionality
Physical & Chemical Stability
• Oxidation Resistance: Special packaging with oxygen barriers prevents oxidation to ferric iron during storage
• Moisture Management: Stable in dry conditions; requires proper sealing to prevent caking in humid environments
Agronomic & Nutritional Functionality
• Chlorophyll Synthesis: Essential for chlorophyll formation in plants, increasing photosynthetic efficiency by 25-30%
• Oxygen Transport: Critical for hemoglobin synthesis in animals, improving oxygen circulation and growth performance

Application
Agriculture - Soil & Foliar Application
• Application: 5-8kg/acre soil application or 0.2-0.5% foliar spray for chlorosis correction
• Benefit: Corrects iron deficiency in citrus, grapes, and ornamentals within 7-10 days
Animal Feed - Nutritional Supplement
• Application: 100-200mg/kg in complete feed for swine and poultry
• Benefit: Prevents anemia, improves hemoglobin levels and growth rates by 15-20%
Water Treatment
• Application: 10-50ppm as reducing agent in wastewater treatment
• Benefit: Effective for phosphate removal and odor control in municipal wastewater
Applications & Solutions
Rapid Correction of Citrus Chlorosis
Targeted soil or foliar application quickly reverses yellowing leaves, improving fruit yield and quality in citrus orchards.
Poultry Feed Fortification for Hemoglobin Support
Consistent inclusion in feed ensures optimal iron levels, preventing anemia and promoting healthy growth rates in broilers and layers.
Efficient Wastewater Treatment
Serves as an effective and economical coagulant for removing phosphates and mitigating odors in industrial and municipal wastewater streams.

FAQ
Q1: Why choose Ferrous Sulphate Monohydrate Powder over the Heptahydrate form for feed and fertilizer?
A: The key advantages are higher iron concentration (≥30% vs. ~19.5%), significantly lower moisture content (≤0.5% vs. ~45%), which drastically reduces caking and improves storage stability, and superior cost-efficiency due to less transport weight and longer shelf life.
Q2: Is this product stable in feed pelleting processes?
A: Yes, its low moisture content and stable crystalline structure make it highly suitable for feed pelleting. It withstands typical processing temperatures better than heptahydrate, with minimal nutrient degradation or quality loss.
Q3: How does the bioavailability compare to more expensive iron chelates?
A: Ferrous Sulphate Monohydrate offers excellent bioavailability of Fe²⁺, often comparable to chelates in many practical applications, but at a substantially lower cost (60-70% savings), providing outstanding value.
