Agriculture & Fertilizer

Applied as iron micronutrient to correct chlorosis (iron deficiency) in crops. Supports chlorophyll synthesis; suitable for soil application, foliar spray and compound fertilizer blending.

Animal Feed

Feed-grade ferrous sulphate provides essential iron for livestock and poultry, preventing anemia and supporting hemoglobin formation in feed premixes.

Pigment & Chemical Industry

Raw material for synthetic iron oxide pigments (red/yellow/black) used in paints, coatings and construction materials.

Concrete & Cement

Used as setting-time regulator and early-strength auxiliary in specific cement formulations.

Note: dosage and application should follow local standards and specific industry requirements.
