Frequently Asked Questions

We manufacture two core commercial grades: Ferrous Sulphate Heptahydrate 19% (FeSO4·7H2O sugar crystalline for soil broadcasting and water treatment) and Ferrous Sulphate Monohydrate 30% (FeSO4·H2O fine powder/granular for compound NPK fertilizer blending and animal feed).

Ferrous Sulphate delivers bioavailable divalent iron (Fe2+) which directly stimulates chlorophyll synthesis and enzyme activation, rapidly reversing yellowing between leaf veins in crops like paddy, groundnut, sugarcane, and citrus orchards.

We supply 20ft FCL container loads of 20 to 27 Metric Tons in palletized 25 kg, 50 kg HDPE bags with moisture-proof LDPE liners or 1000 kg Jumbo Bags dispatched directly via Mundra Port.
