The production method of potassium sulfate compound fertilizer is exquisite. It is produced by the low-temperature conversion of potassium chloride, chemical synthesis and spray-smelting material production technology. It has good stability and contains three major nutrient elements N, P and K which are necessary for plants. Contains trace elements such as S, Ca, Mg, Zn, Fe, and Cu. This fertilizer is suitable for a variety of economic crops, especially the chlorine-free crop. The main components of the potassium sulfate compound fertilizer are MAP (monoammonium phosphate) DAP (diammonium phosphate) and ammonium sulfate (mainly obtained by neutralization of surplus sulfuric acid and gaseous ammonia at low temperature). Potassium sulphate, urea, etc. There are some minor impurities such as calcium sulfate, iron phosphate, aluminum, magnesium salts, and traces of unreacted potassium chloride.
Potassium sulfate compound fertilizer effect:
Multiple nutrients and significant yield increase. It also contains trace elements such as sulfur, iron, zinc, molybdenum, and magnesium that are needed for crops. At the same time, the product has characteristics such as uniform color, stable quality, good solubility, and easy absorption by crops. After application, it can change the ubiquitous soil The imbalance of nutrients, compared with the compound fertilizers produced by other processes, has the characteristics of rapid absorption, low loss, long-lasting fertilizer efficiency, and significant production increase.
Wide adaptability. The product has a high content of active ingredients, and the chlorine root is less than 3%. The product is applicable not only to various agricultural crops such as wheat, rice, corn, and peanuts, but also to economic crops such as fruit trees, vegetables, tobacco, garlic, and ginger. Base fertilizer can be used as top dressing.
Improve soil and enhance soil strength. The product has no toxic or side effects and does not produce any adverse effects on crops and soil. After application, it can quickly add various elements such as potassium, zinc, and boron in the soil, adjust soil structure, enhance national strength, and have drought-resistant moisturizing and lodging resistance. Long-term use can improve soil and increase yield.
Potassium sulfate compound fertilizer use method:
(1) Can be used as base fertilizer. When using potassium sulphate as a basal fertilizer in dry fields, it is necessary to deeply cover the soil to reduce the crystal fixation of potassium and to facilitate the absorption of crop roots and increase the utilization rate.
(2) Used as top dressing. Because potassium is less mobile in the soil, it should be concentrated or applied to the more dense soil layer to promote absorption.
(3) Can be used as seed fertilizer and top dressing. For the amount of fertilizer acres 1.5-2.5 kg, can also be formulated as a 2% -3% solution for top dressing.
