THE STUDIES AND DEVELOPMENTS OF NON-CHLORIDE POTASH IN SOME OF THE WORLD MAIN PRODUCERS

近年来无氯钾肥 (硫酸钾、硝酸钾、钾镁硫酸盐复合肥等 )在农业上的应用品种及数量不断增加。智利、埃及、以色列、约旦、墨西哥、美国等在开采钾矿开发计划中 ,都列入了无氯钾肥的项目。世界上一些主要钾盐生产商不断改进相关的生产工艺并开发出无氯钾盐的新产品。这些研究及应用动态 ,值得关注。

In recent years ,there is an increasing need for non chloride potash (potassium sulphate,potassium nitrate ,potassium magnesium sulphate )in agriculture.
