In presence of soil moisture and enzyme, urea normally hydrolyzes and converts to ammonia and carbon dioxide. The reaction takes place after the urea is dissolved in water. To complete the reaction it takes about 48 hours under the alkaline conditions.
Ammonia gas will volatilize if not protected. Therefore, the urea is put into the soil and not on the soil to conserve fertilizer nitrogen. First name. Last name. Phone number. Helena St. Lucia St. Martin St. Outlying Islands U.

Ammonia contains nitrogen, which mixes with other elements in your body, including carbon, hydrogen, and oxygen, to form urea. Urea is a waste product that is excreted by the kidneys when you urinate. The urine urea nitrogen test determines how much urea is in the urine to assess the amount of protein breakdown. The test can help determine how well the kidneys are functioning and whether your intake of protein is too high or low.
Additionally, it can help diagnose whether you have a problem with protein digestion or absorption from the gut. Your doctor will usually recommend a urea test to determine protein levels in the body. A common test for urea nitrogen is the blood urea nitrogen test , better known as BUN. This article refers to the urine urea nitrogen test, which is performed using a urine sample.
The urine urea nitrogen test involves analyzing urine samples that you collect during a specified hour period. Generally, you will maintain normal eating and drinking habits during the collection phase. Wash your hands carefully before and after collecting each sample. Also, make sure that you cap the containers tightly. Label and return the samples to the doctor as instructed.
Samples need to be refrigerated during the hour period. Note the time, and then collect all urine for the remaining 24 hours. A normal urea level in the urine is 12 to 20 grams over 24 hours. Individual labs may have reference ranges that vary slightly and can be different based on sex or age.
