Chinese Synonyms: Green Vitriol, Iron VitriolpH: 3CAS No.: 7782-63-0Molecular Formula: FeSO₄·7H₂OEnglish Name: Ferrous SulfateMelting Point (℃): 64 (loses 3 molecules of water of crystallization)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 veins. In severe cases, the whole leaf withers, turns white or falls off. Fruit trees and ornamental plants on calcareous soils in northern China are prone to chlorosis. Dosage: (1) Foliar spray: Dilute with water by 800–1200 times, spray evenly on leaves, apply 2–3 times at intervals of 7–10 days. (2) Soil basal or topdressing: 1000–3000 grams per mu for general crops, applied after mixing with organic fertilizer. (3) Injection method: For fruit trees, use 10 mL of 0.1% ferrous sulfate solution (diluted 1000 times). 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 of iron fertilizer easily converts to high-valent iron compounds and becomes ineffective. Therefore, mixing ferrous sulfate with 10–20 times of organic fertilizer as base fertilizer gives better results. Foliar application of 0.2%–0.5% ferrous sulfate aqueous solution is better than soil application. The safe concentration of ferrous sulfate is 0.2%–0.3%. Applications: Agricultural Grade Adjusts soil pH, promotes chlorophyll formation (also known as iron fertilizer), prevents chlorosis in flowers and trees caused by iron deficiency. An essential element for acid-loving plants, especially cycads. Also used as agricultural pesticide to control wheat smut, apple and pear scab, fruit tree rot; used as fertilizer to remove moss and lichen from tree trunks. Packaging & Storage: Woven bag outer packaging with plastic film inner lining. Net weight per bag: 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.

Chinese Name: Potassium SulfateEnglish Name: Potassium sulfateFormula: K₂SO₄Molecular Weight: 174.24CAS No.: 7778-80-5Total Content: 99%Potassium sulfate is also a chemically neutral, physiologically acidic fertilizer. Reactions in different soils and precautions are as follows:Firstly, in acidic soils, excess sulfate ions will increase soil acidity and even intensify the toxicity of active aluminum and iron in the soil to crops. Under waterlogged conditions, excessive sulfate will be reduced to hydrogen sulfide, causing root damage and blackening. Therefore, long-term application of potassium sulfate should be combined with farmyard manure, alkaline phosphate fertilizers and lime to reduce acidity. In practice, drainage and sun-drying measures should also be adopted to improve soil aeration.Secondly, in calcareous soils, sulfate ions react with calcium ions in the soil to form poorly soluble calcium sulfate (gypsum). Excessive calcium sulfate may cause soil compaction, so increasing the application of farmyard manure is recommended.Thirdly, it is mainly used on chlorine-sensitive crops, such as tobacco, tea, grapes, sugarcane, sugar beets, watermelons, potatoes and other tuber crops. Applying potassium sulfate can not only increase yield but also improve product quality. Potassium sulfate is more expensive and less available than potassium chloride, so it should be prioritized on chlorine-sensitive, sulfur-loving and potassium-loving cash crops for better economic benefits.
