Chinese Name: Ferrous SulfateChinese Synonyms: Green Vitriol, Iron VitriolpH: 3CAS No.: 7782-63-0Molecular Formula: FeSO4·7H2OEnglish Name: Ferrous SulfateMelting Point (℃): 64 (loses 3 molecules of crystal water)Relative Density (water=1): 1.897 (15℃)Solubility: Soluble in water and glycerol, insoluble in ethanol.Symptoms of Iron Deficiency: Young leaves show chlorosis while old leaves remain normal. Leaf mesophyll turns yellow but veins stay green, showing netted venation. In severe cases, the whole leaf withers, turns white, or falls off. Fruit trees and ornamental plants on calcareous soils in northern regions are prone to chlorosis. Dosage: (1) Foliar spray: Dilute with water at 800–1200 times, spray evenly on leaves, apply 2–3 times at intervals of 7–10 days. (2) Soil basal or topdressing: 1000–3000 g per mu for general crops, applied mixed with organic fertilizer. (3) Injection method: For fruit trees, use 10 mL of 0.1% ferrous sulfate solution (1000‑fold dilution). Insert the needle into the trunk, hang the infusion bottle on the tree for slow absorption. This method acts quickly, with visible effects in 3 days. (4) Direct soil application may lead to inactivation by conversion to high‑valent iron compounds. Therefore, mixing ferrous sulfate with 10–20 times organic fertilizer as basal fertilizer gives better results. Foliar application of 0.2%–0.5% aqueous solution is more effective than soil application. The safe concentration of ferrous sulfate is 0.2%–0.3%. Application: Agricultural Grade Adjusts soil pH, promotes chlorophyll formation (also known as iron fertilizer), prevents chlorosis in flowers and trees caused by iron deficiency. Essential for acid‑loving plants, especially cycads. Used as agricultural pesticide to control wheat smut, apple and pear scab, and fruit tree canker; also used as fertilizer to remove moss and lichen from tree trunks. Packaging, Storage and Transportation: Woven bag with plastic inner liner. Net weight: 25kg, 50kg, 1000kg, 1250kg or as per customer requirements. Store in dry warehouse, away from fire and heat sources. Cover during transportation to avoid sun exposure, rain and moisture.

Copper sulfate appears as sky-blue or slightly yellowish granular crystals. Its aqueous solution is acidic. It is a protective inorganic fungicide, relatively safe for humans and livestock. Its chemical formula is CuSO4. It usually exists as pentahydrate CuSO4·5H2O, commonly known as blue vitriol; it is a blue rhombic crystal with a density of 2.284 g/cm3. Copper sulfate is an important raw material for preparing other copper compounds. Mixed with lime milk, it can form “Bordeaux mixture” used as an insecticide. Copper sulfate is also used as an electrolyte in the electrolytic refining of copper.Functions and Applications of Copper Sulfate(1) In inorganic industry, used for manufacturing other copper salts such as cuprous chloride, cupric chloride, copper pyrophosphate, cuprous oxide, copper acetate, copper carbonate, etc.(2) In dyestuff and pigment industry, used for producing copper-containing monoazo dyes such as reactive brilliant blue, reactive violet, etc.(3) In organic industry, used as a catalyst for synthesizing intermediates of fragrances and dyestuffs, and as a polymerization inhibitor for methyl methacrylate.(4) In coating industry, used as a fungicide for producing antifouling paints for ship bottoms; in electroplating industry, used as the main salt and copper ion additive for bright acid copper plating.(5) In printing and dyeing industry, used as a mordant and oxygenating agent for fine dyeing of fabrics.(6) Used as a fungicide in agriculture.(7) In breeding industry, used as the main raw material of trace element copper for feed additives.(8) Food-grade copper sulfate can be used as a chelating agent and clarifier in the production of preserved eggs and wine.(9) In biology, used to prepare Fehling’s reagent for detecting reducing sugars and Solution B of Biuret reagent for identifying proteins, usually prepared fresh before use.(10) Used for preparing Bordeaux mixture.
