Urea which is also known as carbamide, is an organic compound of carbon, nitrogen, oxygen and hydrogen. Urea is produced commercially by combining two raw materials, ammonia and carbon dioxide. Urea is the world’s most commonly used nitrogen base fertilizer, and is manufactured by mass more than any other organic chemical. Urea contains 46% nitrogen (N), and it is the most concentrated form of nitrogen fertilizer available. The same chemical compound is produced by the human body; the only difference is in the concentration of the urea. Fertilizer produced in the lab has a more consistent concentration. When applied to the soil, it will convert to ammonia and nitrogen which is needed by plants for growth. Use it as a side dressing on Peas, Beans and Corn. It is water soluble and can be applied to as a foliar feeding spray. Fruit tree recommendations are 2% and can be applied bi-monthly. Urea Fertilizer: How to Use While plants use nitrogen to produce amino acids that help make the proteins that plants need to grow, too much nitrogen encourages stems and leaves at the expense of roots, flowers and fruits. Too little nitrogen stunts the plants’ growth. Applying the correct amount of nitrogen and other nutrients varies according to the plants’ needs and the soil composition. Use a soil test kit or send soil samples out for analysis to determine soil deficiencies and fertilizer recommendations. Plan to apply foliar sprays before 9 a.m. or after 6 p.m., ideally when the temperature is about 72 degrees Fahrenheit, though the acceptable range is between 65 and 85 degrees. A cool, cloudy morning is ideal since the humidity is higher, and the plants’ leaves are able to absorb more of the urea solution, according to University of Missouri Integrated Pest Management. When applying to soil, the urea fertilizer application rate varies according to the plant and season. However, the solution for a foliar spray is different; it is generally a solution of 0.5 and 2 percent urea in water and can go up to 5 percent, according to NMPRO Nursery Management & Production (www.ars.usda.gov/ARSUserFiles/4947/PDFs/2007/2007BiFoliarUreaNMPRO.pdf)Empty packet into 2 gallon of measured water and stir gently. Contents are water soluble and will dissolve rapidly. Apply in early morning or late afternoon.Spray leaves till even saturation and slight run off is achieved.Do not apply to cherry trees.Urea (46-0-0) Nitrogen FertilizerGold Refining Aqua RegiaDescription:Treat your crops to the most potent Nitrogen fertilizer available with this Urea 46-0-0 fertilizer and get the kinds of bountiful yields that make your neighbors jealous.

Product Features: Urea 46-0-0 (46% Nitrogen) 99.9% Pure Great to Improve Nitrogen Deficiency Neutralizing Acid in Aqua Regia Gold Recovery ProcessAPPLICATION RATE:Soil: 2-3 Pounds per 1,000 ft2Note: As a general (albeit not scientific) rule of thumb, the formula for determining the application rate for nitrogen, divide 100 by the percentage of nitrogen in the compound and apply the result to 1,000 sq.ft. For Urea, which contains 46% nitrogen, the formula would be 100/46 = 2.17 lbs. per 1000 sq.ft. Hydroponics: Mix 1-2 tablespoons per gallon of water.*****NOT FOR HUMAN CONSUMPTION*****ANY AQUA REGIA SOLUTION IS TOXIC BY INHALATION AND BOTH VAPOURS AND LIQUID FORMS ARE HIGHLY CORROSIVE ! Aqua Regia solution and vapors emanating from it are extremely corrosive to the skin and respiratory tract.
