Potassium sulfate application instructions

Potassium is one of the three essential elements for crop growth.Potassium sulphate supplier   can promote the synthesis of chlorophyll and participate in the transport of photosynthetic products. Potassium is beneficial to protein synthesis. Potassium can also enhance the nitrogen fixation ability of leguminous crop rhizobia. Potassium can enhance stress resistance, not only can improve plant drought resistance, Resistance to disease, resistance to salt and lodging resistance, but also improve the resistance to the outside world of enduring tolerance, therefore, potassium has “resistance elements,” said. Potassium can regulate the movement of leaf stomata, can control the transpiration of crops to reduce the loss of water, is conducive to economic water plants, especially in arid conditions is more important. Potassium to improve the quality of crop products, potassium to improve the quality of vegetables not only in improving the nutritional content of products, but also in the product can extend the shelf life, can make vegetables have a better appearance, the juice sugar content and acidity are Improve, so that the product flavor thicker, and comprehensively enhance the product value of the product. Potato fertilizer can increase the yield; can improve the cucumber head large tail fine hammer-shaped and tomato potassium deficiency; can increase the potato starch flour and dry matter accumulation, significantly increase the yield; Of the fruit “green back disease”; corn potash fertilizer can reduce the “stem rot” occurred.
Potassium sulfate is a quick-acting physiological acid potash fertilizer, suitable for a variety of soil and a variety of crops, especially for melons, fruits, vegetables, potatoes are more important. Potassium sulfate for basal fertilizer, fertilizer, top dressing can be. As the mobility of potassium in the soil is relatively small, generally the most appropriate base fertilizer, and should pay attention to the depth of fertilization should be centralized or facilities, so that the distribution of fertilizer in the roots of the soil-intensive wetting soil. For topdressing, it should also be applied to the roots of dense soil.
Recommended dosage:
There is no application of nitrogen, phosphorus and potassium fertilizer manure 10-30kg / mu, the general application of 70% base fertilizer, top dressing into about 30%.
The cultivated land that has been applied with the formula fertilizer should be divided according to the crop growth and deficiency symptoms 5-10 kg / mu.
