    Product use and characteristics

    It is a high-concentration nitrogen-phosphorus compound fertilizer (61% of total nutrients), following is the effect on soil when applied as a fertilizer

    1.Urea phosphate can control the soil pH value: the pH of 1% aqueous solution of urea phosphate is 1.89, meanwhile, urea phosphate is a product that dissociates into urea and phosphoric acid when it enters the soil and releases a small amount of unstable complexes of CO2 and NH3. Therefore, when urea phosphate is applied to the soil as a fertilizer and a saline-alkali soil modifier, it will be able to reduce the pH value of the soil or soil micro-regions to a limited extent and change the acid-base balance of the soil, thereby improving the physical and chemical properties of the soil, improving the soil structure, and promoting crop growth effect.

    2.The application of urea phosphate can reduce the ammonia volatilization of the soil: ammonia volatilization is the main way of soil nitrogen loss, in some soils that are conducive to ammonia volatilization, the amount of nitrogen lost by ammonia volatilization can account for 40%-50% of the total soil nitrogen application— Controlling soil ammonium nitrogen content and soil pH value is the key technology to reduce soil ammonia volatilization and improve nitrogen use efficiency. Urea phosphate has a potential advantage in reducing the ammonia volatilization of nitrogen fertilizers in the soil. As an acidic fertilizer, urea phosphate can effectively reduce the pH value of the soil, thereby effectively reducing the volatilization of ammonia in the soil and improving the utilization rate of fertilizers; in addition, urea phosphate can also reduce the hydrolysis rate of urea and reduce the concentration of ammonium nitrogen in the soil content, so it can effectively reduce the rate of soil ammonia volatilization.

    3.Urea phosphate is conducive to the activation of calcium and magnesium in the soil, so it can increase the effect of medium and trace fertilizers: calcium, magnesium, manganese, zinc, etc. are all essential nutrients for plant growth and development, their roles in plant growth and metabolism are important and irreplaceable. In calcareous soil, the total amount of calcium, magnesium, zinc, manganese and other elements is often high, but due to the high pH value of the soil, there is a large amount of OH- in the soil, these nutrients and OH- form solid phase precipitation, resulting in lower effective content of these elements, the application of urea phosphate as an acidic complex nitrogen-phosphorus compound fertilizer can increase the hydrogen ions in the soil and reduce the pH value of the soil, thereby increasing the dissolution of calcium, magnesium, zinc, manganese and other element hydroxide precipitates, so to increase its validity
