Urea, Ammonia

Urea ammonium nitrate solution, commonly referred to as UAN, is a liquid nitrogen fertilizer which is made up of a mixture of urea, ammonium nitrate and water. Nitrogen fertilizer is responsible for the production of amino acids and proteins and indirectly supports the production of vitamin B. Nitrogen application is the main factor to improve plant growth, development and yield of all crops. Usage: The use of modern crop application methods of UAN are designed to provide very precise application of UAN to the crop. Furthermore, UAN applications can provide better economics for the farmer than dry fertilizer applications because the farmer can add other crop protection products like herbicides, insecticides and fungicides to the UAN and can be applied to the crop in a single application.

Urea is the highest nitrogen (46 %) content fertilizer that makes it one of the most vital fertilizers for crops in agriculture. Our supply of Urea from Egypt and MENA region reaches the shores of North America, LATAM countries, Asia, and Europe (Reach Number is available). Product Characteristics: Nitrogen: 46% min. Moisture: 0,5% max. Granulometry granular (between 2 - 4 mm): 90% min.

Agricultural urea N46 46% Properties of urea Urea, also known as carbamide, carbamide and urea. Pure urea is white, tasteless, odorless, needle shaped or prismatic crystal, with a melting point of 132.7 â?? under normal pressure. It is hygroscopic, deliquescent, hydrolyzable, and weakly alkaline. It is made into compound fertilizer with acid fertilizer. Urea is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is a white crystal. Urea is one of the simplest organic compounds. The most important use of urea is as fertilizer. Its nitrogen content is more than 46%. After being converted into ammonium carbonate in soil, urea is hydrolyzed and absorbed by plants. It is the nitrogen fertilizer with the highest nitrogen content at present. Molecular formula of urea: CO (NH2) 2, molecular weight 60.06, density 1.335g/cm �³ï¼? The melting point is 132.7 â??. Soluble in water and alcohol, insoluble in ether and chloroform. It is slightly alkaline. It can react with acid to form salt. It has hydrolysis. Condensation reaction can be carried out at high temperature to produce biuret, triuret and cyanuric acid. Heat to 160 â?? and decompose to generate ammonia gas and turn into cyanic acid at the same time. Urea can be hydrolyzed into ammonia and carbon dioxide under the action of acid, alkali and enzyme (acid and alkali need to be heated). Unstable to heat, heat to 150 â??ï½? 160 â?? to deamination to biuret. Urea is easily soluble in water, 105g can be dissolved in 100ml water at 20 â??, and the aqueous solution shows neutral reaction. There are two kinds of urea products: crystalline urea is white acicular or prismatic crystal with strong hygroscopicity; Granular urea is a translucent particle with a particle size of 1~2mm, which has a smooth appearance and improved moisture absorption. Urea is a physiologically neutral fertilizer, which does not leave any harmful substances in the soil and has no adverse effects after long-term application. However, a small amount of biuret, also known as biuret, will be produced when the temperature is too high during granulation, which has an inhibitory effect on crops. Urea is molecular before conversion and cannot be adsorbed by soil, so it should be prevented from being lost with water; The ammonia formed after conversion is also volatile, so urea should also be deeply covered with soil. Urea is the first synthetic organic substance and widely exists in nature, such as 0.4% urea in fresh human feces. The new version of national standard GB/T2440-2017 for urea has been officially implemented since July 1, 2018. Compared with the replaced 2001 standard, certain adjustments have been made. New standard GB/T2440-2017

Urea, or Carbamide (NH2COONH4), is a synthetic nitrogen-rich fertilizer with a 46-0-0 NPK ratio, essential for crop nutrition. Manufactured from anhydrous ammonia, it's known for its high solubility, neutrality, and low toxicity, making it ideal for agricultural use. Produced via a high-pressure reaction between ammonia and carbon dioxide, urea is both cost-effective and widely used in the agriculture and chemical industries. It breaks down in soil to nourish plants effectively. Safety Note: Handle with care to avoid skin and eye irritation or respiratory issues. Urea is generally safe but can produce toxic vapors when heated excessively.

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.

CASå?·:57-13-6 Urea for vehicles, agricultural urea, urea N46ï¼? When the temperature of urea is below 20 â?? and the relative humidity is below 70%, it will not only not absorb moisture, but also evaporate water and reduce its water content; When the temperature exceeds 20 â?? and the relative humidity is higher than 80%, it starts to absorb moisture, and becomes paste when it is serious. When the air is dried again, it will re agglomerate, which is only inferior to ammonium nitrate. When the urea aqueous solution is at 80 â??, hydrolysis and decomposition reactions will occur, forming ammonium carbamate, ammonia gas and carbon dioxide respectively. Under acid and alkaline conditions, urea will decompose faster when it is heated. Urea is easy to combine with straight chain carbohydrates to form crystalline additional compounds; It forms a variety of double salts with various inorganic compounds, such as Ca (NO3) 2 �· 4CO (NH2) 2, NH4Cl �· CO (NH2) 2, CaChemicalbookSO4 �· 4CO (NH2) 2, MgSO4 �· 4CO (NH2) 2 �· 3H2O, Mg (NO3) �· 4CO (NH2) 2 �· 2H2O, etc; It is easy to form urea phosphate, dicalcium phosphate and water with monocalcium phosphate, namely Ca (H2PO4) 2 �· H2O+CO (NH2) 2 â?? H3PO4 �· CO (NH2) 2+CaHPO4+H2O; With nitric acid, it is easy to form urea nitrate, CO (NH2) 2+HNO3 â?? CO (NH2) 2 �· HNO3, which combines and relaxes the two; It can combine with formaldehyde to form urea formaldehyde compounds (uric acid rubber shrinks), in which the higher proportion of formaldehyde is urea resin, and the lower proportion is slow-release (effective) urea.
