Potassium Sulfate Production Process:
The production of this chemical is done in different ways: The reaction of potassium chloride with Langbeinite ore, the reaction of potassium chloride with sulfuric acid or sulfur dioxide, and also the recycling of sugar waste are some of the methods used to produce this chemical compound.
Potassium Sulfate Uses:
This known chemical compound has many applications in industry such as Agrochemicals (non-pesticides), Catalysts, Laboratory chemicals
- The most important use of potassium sulfate in agriculture is to meet the plant’s need for potassium and sulfur.
- Potassium sulfate reduces soil acidity and helps to better absorb iron and phosphorus.
- Strengthens plant nodes with high carbohydrates such as potatoes.
- Improve the color quality and taste of fruits.
- In the food industry as a flavoring.
- As a substitute for common salt (sodium chloride).
- This compound is also used in the glass industry.
What is Potassium Sulfate used for in Agriculture?
Most of the consumption of potassium sulfate is in the agricultural industry and as an agricultural fertilizer to supply potassium and soil sulfur. Potassium is needed to complete many essential functions in plants, including activating enzymatic reactions, synthesizing proteins, forming starches and sugars, and regulating water flow in cells and leaves. Often the concentration of K in the soil is too low to support the growth of a healthy plant.
One of the most important and best properties of potassium sulfate should be noted that, unlike other fertilizers, it does not cause soil salinity, so it is very suitable for products that are sensitive to chlorine. These agricultural products include pistachios, tea, citrus fruits, tobacco, potatoes, berries, grapes, etc. Of course, it should be noted that chemical fertilizers such as potassium sulfate are not suitable for nitrogen-based products and do not have the necessary efficiency in these cases.

Will potassium sulfate lower pH?
china chemicals –
Potassium sulfate cannot be used to lower soil pH, but this fertilizer causes confusion on this issue because it contains sulfur and because it sounds similar to aluminum sulfate; both of these materials are used to acidify the soil.
