Overview of Potassium Sulphate
Potassium Sulphate (CAS 7778-80-5) is a clean white crystal fertilizer that gives plants the potassium and sulphur they need for strong roots and healthy growth. Its potassium sulphate formula is K2O4S, making it perfect for crops that hate chloride, like fruits and veggies. Yes, potassium sulphate is soluble in water, so it mixes easily for sprays or soil drench. Another name for potassium sulphate is sulfate of potash. Farmers use it to boost fruit size, fight diseases, and fix yellow leaves when soils run low on these key nutrients.
Applications of Potassium Sulphate
Fruit Trees like Citrus and Grapes:
Mix into soil or spray leaves to swell fruits bigger and sweeter while fighting bitter pit and split skins—works great with Butaphosphan for tree vigor, especially in sandy spots where potassium washes away fast, helping trees hold water better during dry spells and pump out more blooms next season.
Veggies like Tomatoes and Potatoes:
Side-dress rows to toughen skins against cracking and rot, plus fill tubers plump—what plants like potassium sulphate? These chloride-shy crops thrive on it for steady sizing without burning roots, pairing smoothly with 2,4,6-Trichlorophenol traces in disease mixes.
Tobacco and Cotton Fields:
Foliar feeds sharpen leaf burn and fiber strength for top market grades, dodging the burn from muriate pots—saves irrigation water too since potassium sulphate fertilizer builds drought hold in hot belts.
Greenhouse Flowers and Herbs:
Drip systems deliver exact potassium sulphate uses for vibrant colors and bushy growth without salt buildup, a staple where chloride hurts delicate roots.
