As an environmental protection product for crops,urea phosphate is characterized by less dosage and no residue. It is a must-use fertilizer for exporting fruits and vegetables. So what exactly is urea phosphate? What does it do to the soil?

What exactly is urea phosphate?

Urea phosphate is an improved fertilizer for saline-alkali soil, with no impurities, fast absorption, no chloride ions, urinary nitrogen and phosphate phosphorus. It is easily absorbed by crops quickly, with obvious effect and long-lasting stability. The utilization rate of phosphorus and ammonium nitrogen in urea phosphate is 98%, while the utilization rate of conventional phosphorus fertilizer is only 10 to 15%. Urea phosphate is an improved fertilizer for saline-alkali soils. It has no impurities, fast absorption, no chloride ions, ammonium nitrogen and phosphate phosphorus. It is easily absorbed by crops and has obvious effects and is lasting and stable. Urea phosphate can effectively control the volatilization of soil ammonia. , Activation of micronutrients. It can effectively control soil ammonia volatilization, activate medium and ...
... micronutrient elements, and realize the role of increasing agricultural income and reducing costs.

Analysis of Effect of Urea Phosphate on Soil

Urea phosphate controls soil pH

In acidic red soil and alkaline silt loam, the pH of the soil micro-zone will increase during the hydrolysis of conventional urea to NH4+ under the action of urease. In acidic soils, elevated pH is beneficial for reducing soil aluminum toxicity to plants. For the large area of calcareous soil area in northern my country, especially the alkaline soil area, the increase of soil pH value is unfavorable for soil physical and chemical properties, soil structure, plant growth and agricultural production in this area. At the same time, urea phosphate is also an unstable complex that dissociates into urea and phosphoric acid when it enters the soil, and releases a small amount of CO2 and NH3. Therefore, when urea phosphate is applied to the soil as a fertilizer and a saline-alkali soil conditioner, it will be able to reduce the pH value of the soil body or soil micro-zone 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, etc. effect.

Can reduce ammonia volatilization from 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 nitrogen application in the soil. Therefore, reducing ammonia volatilization is one of the important ways to provide nitrogen fertilizer utilization. Controlling soil ammonium nitrogen content and soil pH is the key technology to reduce soil ammonia volatilization and improve nitrogen fertilizer utilization. Urea phosphate has potential advantages in reducing ammonia volatilization of nitrogen fertilizers in 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 fertilizer; in addition, urea phosphate can also reduce the hydrolysis rate of urea and reduce the amount of ammonium nitrogen in the soil. It can effectively reduce the rate of soil ammonia volatilization.

It is beneficial to activate calcium and magnesium in the soil, and increase the effect of medium and trace fertilizers

Ordinary phosphate fertilizer enters the soil and forms insoluble precipitates by interacting with medium nutrients such as calcium and magnesium, as well as nutrients such as zinc and manganese in the soil. This reduces the activity of calcium, magnesium, zinc and manganese in the soil and also reduces the seasonal utilization of phosphorus fertilizers. The use of urea phosphate as an acidic complex nitrogen-phosphorus compound fertilizer can not only increase the hydrogen ions in the soil, but also reduce the pH value of the soil, thereby increasing the dissolution of calcium, magnesium, zinc, and manganese and other element hydroxide precipitates, increasing its effectiveness.
