Urea N46% is a common nitrogen fertilizer that is widely used in agriculture. The specifications of Urea N46% can vary depending on the producer and the country of origin, but some of the general specifications are as follows: Nitrogen content (N): 46% minimum Biuret content: 1% maximum Moisture content: 0.5% maximum Granulometry: 90% of particles shall pass through 2.80mm sieve and be retained on 1.00mm sieve. Color: Pure white Free ammonia: 160 PXT PPM maximum Melting point: 132-135 degrees Celsius Radiation: Non-radioactive Physical state: Solid pH: 7.5-8.0 It's important to note that these specifications are general and may vary slightly depending on the producer or the region of origin. The specifications of Urea N46% are important to ensure that it is of high quality and safe for use in agricultural applications. Urea N46% is primarily used as a nitrogen fertilizer in agriculture. Nitrogen is a key element in plant growth, and urea N46% is a highly concentrated source of nitrogen. When applied to soil, it is converted into ammonium, which can be taken up by plant roots. Urea N46% is used on a wide variety of crops, including corn, wheat, rice, soybeans, and many others. It is commonly used in both conventional and organic farming practices to promote healthy plant growth and increase crop yields. The use of urea N46% can help to increase protein content in crops such as wheat, barley, and oats. In addition to its use as a fertilizer, urea N46% is also used in the production of animal feed, where it is added to increase the protein content of the feed. It is also used in the production of some plastics, resins, and adhesives. Overall, urea N46% is a versatile product that is widely used in agriculture and other industries due to its high nitrogen content and easy availability.
