Potassium sulfate compound fertilizer is a physiological acidic fertilizer, therefore, ph value is less than 7. Potassium sulphate fertilizers are acidic fertilizers that generally affect crop choice of fertilizer. Common, such as the soil is alkaline, choose fertilizer, you can use potassium sulfate compound fertilizer, such as soil is acidic, the general choice of alkaline fertilizers.
Sulfuric acid compound fertilizer containing sulfur, can improve the status of soil sulfur deficiency, acid fertilizer can adjust the alkaline soil pH, prevent soil salinization. At the same time, most of the crops like potassium sulfate application of potassium fertilizer, the effective increase crop quality and yield.
What is the common lack of sulfur?
(1) far away from the town, by the chimneys and dust pollution in areas less;
(2) long-term diammonium phosphate instead of 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) (4) In the areas with large sand and saline-alkali soils, the soils lack of sulfur, potassium, or potassium, or the soils with poor soil fertility and poor soil fertility are more likely to be deficient than those in vegetables and fruit trees. (5) Soybeans, rapeseed and other crops like sulfur may be more susceptible to sulfur deficiency than other crops.
At this point the situation of sulfur deficiency in soil potassium sulfate compound fertilizer, balanced soil pH, the rational use of potassium sulfate compound fertilizer, effectively improve crop quality and yield.
