The use of potassium sulfate should be noted

Fertilizer for different crops, there are a variety of different needs, we have specific issues in the specific analysis should pay attention to the use of matters. The role of potassium sulfate nutrition. Potassium sulfate can provide or improve crop sulfur nutrition, when the soil available sulfur content (S) is less than 12 mg / kg, the general crop will be sulfur deficiency. Xiaobian give you the following points under the required use of potassium sulfate.
In the following cases more likely to lack:
① far away from the town, by chimneys and dust pollution in areas less;
② long-term diammonium phosphate instead of calcium superphosphate and phosphate rock, urea, ammonium bicarbonate instead of ammonium sulfate, that is not the area of sulfur fertilizer, especially in the northwest and northeast and other remote areas; ③ long-term organic fertilizer , Lack of application or degradation of soil fertility in the more serious areas, of which field crops may be more than vegetables, fruit trees are more susceptible to sulfur deficiency; ④ soil and saline soil area of ?? a larger area, soil sulfur, potassium or polychloride than other regions More need to use potassium sulfate; ⑤ soybeans, rapeseed and other crops like sulfur may be more than the lack of sulfur or need more potassium sulfate.
