How is Urea Phosphate UP made?
This product is made from urea and phosphoric acid through chemical reaction. Place urea in an enameled reactor, heat it to 60 degrees to melt it, slowly add phosphoric acid, stir while adding, white smoke comes out of the reactor, the temperature rises to about 80 degrees, and continue stirring for two hours until the material becomes a paste. Pour it into a stainless steel plate and cool it. After it condenses into blocks, it is broken, dried with hot air, and ground into fine powder to get Urea Phosphate UP. Its method is similar to compounding medicine. If the proportion is not appropriate, the combination will be incomplete. Too much urea will taste fishy, and too much phosphoric acid will taste sour. Only the accurate ratio will be a good product.
What is the appearance of Urea Phosphate UP?
It is mostly white crystalline powder, light in weight, soft when pinched, and easy to fly. Looking at its fine crystals, it looks like broken jade powder with a soft luster. It is soluble in water, and its aqueous solution is acidic with a pH value of about 1.8, and it can be dissolved in metal oxides. It is hygroscopic and will clump after being placed in a wetland for ten days, so it needs to be kept away from moisture. It decomposes into urea and phosphoric acid when it meets alkali, releasing ammonia smell, so it cannot be stored with lime. It is easy to decompose at high temperature, so the place where it is stored needs to be cool and away from heat sources. Its powder is slightly cool to the touch, and absorbs heat when dissolved in water, cooling the solution.
Where can Urea Phosphate UP be applied?
In agriculture, it is a good slow-release fertilizer, containing nitrogen and phosphorus. It is applied to fruit trees and tea trees, and the fertilizer effect is long-lasting, which can promote the development of root systems and reduce loss; it can be applied to alkaline soil to adjust the pH. In industry, it is a key product for rust removers, used for metal surface treatment, which can remove rust and make the surface smooth; in feed, it is an additive to supplement nitrogen and phosphorus for livestock and poultry and promote growth. In addition, in water treatment, it can be used as an algaecide to inhibit algae reproduction; in printing and dyeing, it can be used as a fixing agent to make the color last. Its use is like spring rain, moistening everything and helping it grow.
How should Urea Phosphate UP be stored?
It should be packed in double-layer thick plastic bags, the inner bag should be heat-sealed, and the outer bag should be tied tightly. It should be placed in a ventilated and dry warehouse, with wooden boards and oil paper on the ground to keep the material one foot and five inches above the ground. The stack height should not exceed six layers to prevent the bottom layer from being compressed and agglomerated. The warehouse should be equipped with calcium chloride desiccant tanks, and the temperature should be controlled below 30 degrees. During the rainy season, ventilation should be carried out for two hours every day. Transport on a cool day to avoid exposure to the sun, and the carriage should be covered with tarpaulin to prevent moisture. Stop the car to avoid rain. If it agglomerates, it can be placed in a stone mill to grind it into fine powder, and the fertilizer effect will not be reduced. It is only necessary to prevent impurities from mixing in. The key to storage is to keep it at a low temperature and prevent moisture, and it is better to use it quickly.
What is the difference between Urea Phosphate UP and Monoammonium Phosphate MAP?
Although both contain phosphorus and nitrogen sources, they have different nitrogen sources and properties. Urea Phosphate UP uses urea as nitrogen source, and its aqueous solution is more acidic; Monoammonium Phosphate MAP uses ammonia as nitrogen source, and its acidity is slightly weaker. In terms of usage, the former is suitable for slow-release fertilizer and rust remover, while the latter is more suitable for foliar fertilizer and fire extinguisher. The production methods are also different. The former is made by combining urea and phosphoric acid, while the latter is neutralized by ammonia and phosphoric acid. For example, rice and wheat are both grains, but they have different properties, so growers should choose the appropriate one.
