POTASSIUM SULPHATE APPLICATION IN AGRICULTURE Potassium sulfate is a colorless crystal, moisture absorption, easy to agglomerate, good physical properties, ease of administration, is a good water-soluble potash. Potassium sulfate is chemically neutral, physiological acidic fertilizer. Potassium is a chlorine-free, high quality and efficient fertilizer, especially in the tobacco, grapes, beets, tea, potatoes, flax and various fruit trees and other chlorine-sensitive crops industry, is an important and indispensable fertilizer; it is also the quality the main raw material of nitrogen, phosphorus and potassium in NPK. Potassium sulfate compound fertilizer potassium chloride low temperature conversion, chemical synthesis, spray granulation process from production, good stability, in addition to containing N, P, K three major plant nutrients essential, but also contain S, Ca , Mg, Zn, Fe, Cu and other trace elements. Such fertilizer is suitable for a variety of economic crops, espec...

METHOD FOR PREPARING FOOD GRADE POTASSIUM SULFITE In recent years, with the continuous development of the economy and the level of science and technology also continues to increase, food grade potassium metabisulfite is a kind of food additives that we will use in food production and processing activities, the use of food additives such as not only improves the work efficiency, but also for our production is helpful. But a lot of people on food grade potassium potassium sulfate is not very understanding of the relevant knowledge, today we will give you a brief introduction to the food grade potassium sulfite preparation method. Hope that our introduction to all of us help, the following and a small make up to see it! Method for preparing food grade potassium sulfite Food grade potassium metabisulfite for sulfate of potash minerals and potassium brine as raw material to produce the Saline Lake can be prepared.
