Product Description

Potassium sulfate is a commonly used potassium fertilizer, which has the effects of improving crop stress resistance, promoting crop growth, improving soil structure, enhancing crop nutrient absorption and increasing crop yield. When using potassium sulfate as a fertilizer, consult a professional agronomist or follow the package instructions.
1. Improve crop stress resistance
Because potassium ions in potassium sulfate can stimulate plants to produce more osmoregulatory substances, so as to help plants better resist drought, salt and other environmental pressures. By enhancing the resistance of plants to reduce the damage caused by adverse environment to crops, so as to ensure their normal growth and development and achieve the goal of increasing production.
2. Promote crop growth
Because the potassium in potassium sulfate is necessary for many enzymatic reactions and metabolic processes, it can effectively promote photosynthesis, speed up the transport of carbohydrates, and is conducive to protein synthesis and accumulation. Potassium can promote the development of roots, make the stems of the plant thick and strong, the leaf color is dark green, improve the efficiency of photosynthesis, promote nitrogen absorption and utilization, and promote the growth of crops.
3. Improve soil structure
The application of potassium sulfate can form a stable aggregate in the soil, improve the physical properties of the soil, improve air permeability and water permeability, promote microbial activity, and facilitate the decomposition of organic matter and nutrient conversion. Good soil structure helps maintain a balance of water and nutrients, preventing soil erosion, and also helps roots spread and absorb nutrients.
4. Enhance crop nutrient absorption
Potassium has the effect of enhancing crop nutrient absorption because it participates in a variety of enzymatic reactions and metabolic pathways, and plays an important role in promoting the absorption and utilization of other nutrient elements such as nitrogen and phosphorus by plants. Appropriate application of potassium sulfate can help crops make more efficient use of limited nutrient resources and avoid nutrient waste and environmental pollution.
5. Increase crop yields
Potassium can promote photosynthesis and increase the photosynthetic rate of crops, thus increasing the accumulation of organic matter. In addition, potassium can also promote the absorption and utilization of nitrogen by crops and improve the biomass of crops. The application of potassium fertilizer can significantly increase the yield of crops, especially in potassium-deficient areas or potassium-deficient crops.
 

Potassium sulfate contains 46%~52% potassium, is a high concentration of fast-acting potassium fertilizer, used to supplement potassium. Potassium sulfate is suitable for all kinds of soil, in fruits and vegetables, field crops, cash crops and fruit trees can be used.

Potassium sulfate fertilizer can be used as base fertilizer, seed fertilizer and topdressing fertilizer, and has many uses.
 

 

1.Potassium sulfate fertilizer is suitable for all kinds of soil, especially in neutral and alkaline soil. In some sandy loam or red soil, the application of potassium sulfate fertilizer can supplement the potassium and sulfur required for crop growth and improve soil fertility. The potassium in the potassium sulfate fertilizer is generally not adsorbed by the soil, and the utilization rate is high.
2.Potassium sulfate fertilizer applied to a variety of crops, can quickly supplement the potassium required for crop growth. It is especially suitable for sweet potatoes, potatoes, watermelon, tobacco and fruits and vegetables in greenhouses, which can not only improve the growth of crops, but also improve the taste, which is the role of potassium chloride can not be achieved. In garlic, the use of potassium sulfate can also play a role in improving quality. Because garlic loves sulfur, using potassium sulfate can enhance the flavor of garlic and promote bulb growth.
3.After the use of potassium sulfate fertilizer, it is conducive to improving the stress resistance and cold resistance of crops.

Potassium sulfate for agricultural use is a relatively high quality fertilizer.


It is physiologically acidic. From white to light yellow in a powdery form. It is easily soluble in water and belongs to the quick-acting fertilizer that is easily absorbed. It can be applied as a base fertilizer or topdressing fertilizer. Applied to some crops that require more potassium and less chlorine, or some crops that require more sulfur will have a good effect. When used as a base fertilizer, it should be applied intensively, and potassium sulfate should be applied to the wet soil layer of the crop. Potassium sulfate is applied to soil or crops when applied as topdressing.
It should be preferentially used on crops that avoid chloride, such as sweet potatoes, potatoes, watermelon and other crops.
Potassium sulfate fertilizer is mainly used for base fertilizer, seed fertilizer and topdressing, and the amount of fertilizer applied is also different for different needs of crops. Potassium sulfate moves little in the soil, and the effect of base fertilizer is better than that of topdressing.


When applying the bottom fertilizer, potassium sulfate fertilizer should be combined with nitrogen fertilizer and potassium fertilizer, generally 30 to 40 pounds per mu. When potassium sulfate fertilizer is used as topdressing, the earlier the time of topdressing, the higher the utilization rate, generally 10 to 15 catties per mu. Potassium sulfate can also be sprayed as a leaf surface, and the spray concentration of vegetables is 0.2% to 0.3%.

When applying potassium sulfate fertilizer to the root, it is best to cover the soil deeply, and use it with nitrogen fertilizer, phosphate fertilizer and medium and trace elements, so as to achieve the effect of increasing production. There are potassium sulfate fertilizer, potassium nitrate fertilizer and potassium chloride fertilizer in potassium fertilizer, and there are also differences in use. For example, when planting fruits and vegetables in greenhouses, potassium sulfate and potassium nitrate are mainly used, which is conducive to the expansion of the fruit, but potassium sulfate is used in the color transformation period, which is conducive to the color transformation of the fruit and improve the commerciality.

Potassium sulfate also has a certain effect on acidifying root soil. It can promote crop absorption of phosphorus and trace elements in the soil, which is especially important for crops at seedling stage.

Precautions for applying agricultural potassium sulfate:
It is necessary to apply in a targeted way to better play the role of potassium sulfate. For various crops or soils, priority should be given to crops and soils that require potassium sulfate, and for crops in fruit and vegetable fields (large areas of fruit and vegetable planting), potassium sulfate is generally more necessary. When planting many kinds of crops, the use of potassium sulfate in fruits and vegetables should be given priority.
For saline-alkali soil or sandy soil in arid areas, field crops such as rape, beans, sugar and other crops, potassium sulfate is more needed. In the process of applying potassium sulfate, it is necessary to match reasonably, and potassium fertilizer cannot be blindly applied. Potassium sulfate can be combined with other nutrients such as nitrogen and phosphate fertilizers to achieve a comprehensive effect.

Most practical and experimental studies have shown that higher yields can be achieved only by applying fertilizers that the crops need and lack. Better, greener produce. In the process of soil testing and fertilization, it is necessary to prevent excessive one-time fertilization resulting in soil or crop calcium deficiency, magnesium deficiency, etc., and to control its dosage in a suitable and reasonable range during application.
