Agricultural application:

Potassium sulfate is a colorless crystals, hygroscopicity is small, not easy to agglomerate, good physical properties, application is convenient, is a good water soluble potash.Potassium sulfate is chemically neutral, physiological acid fertilizer.Potassium sulfate is a kind of free chlorine, quality and efficient potash, particularly in the tobacco, potatoes, flax, grape, sugar beet, tea tree and various kinds of fruit trees and avoid chlorine crop planting, fertilizer is an important and indispensable;It is also a high quality nitrogen, phosphorus and potassium ternary compound fertilizer, the main raw material.

Type potassium sulphate compound fertilizer with potassium chloride conversion at low temperature, chemical synthesis, spray granulation process and become, good stability, in addition to containing plant required three major nutrient elements N, P, K, still contain S, Ca, Mg, trace elements zinc, Fe, Cu, etc.This kind of fertilizer is suitable for all kinds of economic crops, especially avoid chlorine crops.The main components of the potassium type compound fertilizer has the MAP (monoammonium phosphate (DAP) (DAP), ammonium sulfate (mainly is the transformation of surplus sulfuric acid at low temperature and gas ammonia neutralization).Potassium sulphate, urea, etc and some other small amounts of impurities such as calcium sulphate, iron, aluminum, magnesium salt and phosphate reaction trace not fully potassium chloride.

Using attention:

Using the matters needing attention

First, in acidic soil, the excess sulfuric acid root causes soil acidity is aggravating, even aggravate the soil active aluminum, iron poisoning crops.Under flooded conditions, extra sulfate can be restored to generate hydrogen sulfide, change to the root victims to black.So, long-term consumption of potassium sulphate to cooperate with farmyard manure, alkaline phosphate and lime, reduce acidity, should also be combined with drainage field drying measures in practice, improve ventilation.

Second, in calcareous soil, sulfate and calcium ions in the soil is not easy to dissolve the calcium sulfate (gypsum).Calcium sulphate too much can cause soil harden, should pay attention to the quality of farm at this time.

Third, mainly used in the avoid chlorine crops, such as tobacco, tea, grape, sugar cane, sugar beet, watermelon, potato and so on increasing potassium sulfate production not only improve, also can improve the quality.Potassium sulfate is potassium chloride is expensive, less supply of goods, should focus on is sensitive to chlorine, potassium and sulfur xi xi economic crops benefit will be better.

Fourth, this kind of fertilizer are the physiological acid salt, applying in alkaline soil can reduce the soil PH
