The urine urea nitrogen test measures the amount of urea in your urine. It can indicate how much protein you're eating and how the kidneys are functioning.

However, the researchers did discover that urine fertilization increased the relative amounts of nitrifying and denitrifying groups compared to synthetic fertilizer—implying that more nitrogen oxides ...

A team of chemists and agriculture specialists has developed a way to transform urea in wastewater, into percarbamide, which ...

If pouring 1,000 gallons of urine on an acre, there are about 50 pounds of nitrogen added. Using a concentrate 10 times stronger than diluted urine, only 100 gallons would need to be applied to ...

Urine has large amounts of nitrogen, phosphorus, and potassium. Nitrogen content in urine is high, mostly in urea, which makes up more than 50 percent of the total organic acids.

When they passed electricity through the solution, solid crystals of percarbamide formed, made from oxygen in the air, hydrogen from water and urea from the urine. These crystals could then be ...

Urea nitrogen is produced when the body breaks down protein. The liver releases it into the blood and sends it to the kidneys, to be removed in the urine. A BUN test can show the fitness of the ...

The serum urea nitrogen was 175 mg., and the creatinine 17.8 mg. per 100 ml.; the sodium was 130 milliequiv., the potassium 7.6 milliequiv., the carbon dioxide combining power 11.3 milliequiv ...

Urine-soaked leather makes it soft: Prior to the ability to synthesize chemicals in the lab, urine was a quick and rich source of urea, a nitrogen-based organic compound.

Hibernating ground squirrels stay in shape by recycling urea, the main compound in urine, with the help of their gut microbes. When animals hibernate, they enter a state of suspended animation ...
