硫酸钾是仅次于氯化钾的商品钾肥。全世界硫酸钾的产量约占钾肥总量的7%左右,美国、苏联以及西欧等国均有生产。特性及生产硫酸钾含氧化钾(K_2O)50%左右,为白色或淡黄色结晶。易溶予水,属生理酸性肥。对农作物的适应性硫酸钾比氯化钾好,在一些忌氯作物,如烟草、茶叶、葡萄、马铃薯上施钾肥,必需施用硫酸钾,而不能施用氯化钾。但由于硫酸钾的生产工艺比较复杂,且成本较高,又少见巨型钾盐矿床,因而限制了
Potassium sulfate is second only to potassium chloride commercial potash. The output of potassium sulfate accounts for about 7% of the total potassium in the world. The United States, the Soviet Union and other countries in Western Europe have their own production. Characteristics and production Potassium sulfate potassium oxide (K_2O) about 50%, white or light yellow crystal. Water soluble, is a physiological acid fertilizer. Adaptability to Crops Potassium sulphate is better than potassium chloride. Potassium sulphate must be applied to some crops that avoid chlorine, such as tobacco, tea, grapes and potatoes. Potassium sulphate must not be used. However, the production process of potassium sulfate is more complex and costly, and rare giant potash deposits, thus limiting
