Agricultural potassium sulfate is a product often used in the process of crop growth, which can promote the growth of crops and improve crop yield. What are the effects of potassium sulfate for agriculture? How to use it? Please read on below:

Potassium sulfate is a physiologically acidic fertilizer. The relatively higher or faster absorption of potassium ions by crops than sulfate ions will lead to acidification of rhizosphere soil, thus improving the availability of soil phosphorus and medium and trace element nutrients. This physiological acidification is especially important for rice seedling cultivation in northern China. In order to cultivate strong seedlings and reduce pests and diseases, it is required to control the pH value of the seedling bed soil or nutrient soil of rice seedlings in 4.5~5.5, to this end, in addition to the acid adjustment with sulfuric acid water and the appropriate application of ammonium sulfate nitrogen fertilizer, potassium sulfate should be selected, 50 grams per square meter, or 5 grams per seedling tray. This is helpful for acidifying rhizosphere soils.

Improve the pertinence of application of potassium sulfate fertilizer. Potassium sulfate has a broad spectrum for a variety of soils and crops, but its price is higher, so it is better to make steel on the edge. When there are several different soils and crops at the same time, priority should be given to the most needed crops or soils, such as fruit trees, vegetables and other cash crops need potassium sulfate more than general field crops; In field crops, legumes, oilseed rape, potato and sugar crops needed potassium sulfate more than other crops. Saline-alkali soil and sandy soil in arid regions need potassium sulfate more than ordinary soil.

Apply balanced fertilization. The balanced fertilization mentioned here refers to the combination of potassium fertilizer with nitrogen and phosphate fertilizer and other nutrient fertilizers. A large number of production practices and scientific tests have proved that only by combining the necessary and lacking nutrients of crops and closely cooperating with other agricultural production measures can we achieve the comprehensive benefit goal of high quality, high yield, high efficiency and environmental protection. Special attention should be paid to controlling the fertilizer amount at the appropriate level by testing the soil and fertilizing, and to prevent the crop from calcium and magnesium deficiency due to excessive potassium application at one time.

Potassium sulfate is colorless crystal, small hygroscopic, not easy to caking, good physical properties, easy to apply, is a very good water-soluble potassium fertilizer. Potassium sulfate is also a chemically neutral, physiologically acidic fertilizer. Potassium sulfate is a kind of chlorine-free, high quality and efficient potassium fertilizer, especially in the cultivation of chlorine-sensitive crops such as tobacco, grapes, beets, tea trees, potatoes, flax and various fruit trees. It is also the main raw material of high-quality nitrogen, phosphorus and potassium ternary compound fertilizer

The use of potassium sulfate is mainly used as fertilizer, especially for cash crops that avoid chlorine. It can also be used to manufacture potassium persulfate, potassium carbonate, potassium water glass, etc. It is also used in the pharmaceutical industry.

Potassium sulfate has a wide range of uses and is often used as a drug (such as a laxative), fertilizer (contains about 50% potassium, is a fast-acting potassium fertilizer, can be used as a base fertilizer, seed fertilizer and topdressing). It is also used to make alum, glass and potassium carbonate. It is used as a chemical fertilizer in agriculture. It's the raw material for making potassium salt. The dye industry is used to make intermediates. Glass industry as a clarifying agent. The spice industry is used as an additive. It is used medically as a laxative. Used as a general additive in the food industry. It is also used for biochemical test of serum protein. It can also be used as medicine, potassium fertilizer, and for making alum, glass and potassium carbonate, etc., and can be used as a dietary salt substitute.
