Detail Information
What is Ferrous Sulphate Heptahydrate Crystalline 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: Apply 5-10kg per hectare via soil application or a 0.1%-0.3% solution for foliar spray.
• Benefit: Effectively prevents and corrects zinc deficiency in crops like corn (preventing "white bud") and citrus, improving yield and fruit quality.
Animal Feed – Nutritional Supplement
• Application: Homogeneously mix into premixes or complete feed at recommended dosages (e.g., 100-200mg/kg for swine).
• Benefit: Ensures optimal growth, supports immune system, and improves skin and hoof health in livestock.
Industrial Uses
• Application: Serves as a raw material in the production of electrolytes, zinc plating, and as a mordant in dyeing.
• Benefit: Provides a reliable and pure source of zinc ions for various chemical processes.
Applications & Solutions
Citrus Orchard Zinc Deficiency Correction
Foliar spray at flowering stage increases fruit set rate by 25% and Brix by 1.5°
Livestock Feed Supplementation
Soil application prevents "white seedling" disease and increases yield by 15%
Industrial Uses
Provides a reliable and pure source of zinc ions for various chemical processes.

FAQ
Q1: What is the main difference between Zinc Sulphate Heptahydrate and Monohydrate?
A: The primary differences are zinc content and physical form. Heptahydrate contains about 22% Zn and is crystalline, ideal for fast-dissolving applications. Monohydrate (ZnSO₄·H₂O) has about 33% Zn, is typically a powder, and offers a higher concentration of zinc per unit weight.
Q2: Is Zinc Sulphate Heptahydrate safe for my crops and animals?
A: Yes, when used as directed. It is an essential micronutrient source. However, always follow recommended application rates to avoid overexposure. Our product is manufactured with strict heavy metal controls for your safety
Q3: How should I store this product to maintain its quality?
A: Store in a cool, dry, and well-ventilated place. Keep the packaging sealed to prevent moisture absorption and weathering
