Urea - Wikipedia
Urea, also known as carbamide, is an organic compound with chemical formula CO(NH 2) 2. This amide has twoNH 2 groups joined by a carbonyl (C=O) functional group. Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals.CH₄N₂O 60.056 g·mol−1 133 to 135 °C (271 to 275 °F; 406 to 408 K) 1079 g/L (20 °C), 1670 g/L (40 °C), 2510 g/L (60 °C), 4000 g/L (80 °C)

FORMULAS OF UREA NITROGEN FERTILIZERSMAKING LIQUID
Why is Urea Different? Urea is a somewhat unique fertilizer material because it contains neither Nitrate-N or Ammonium-N. When placed in the soil, however, it quickly converts (usually within 2-10 days depending on soil temperature) to Ammonium-N. Urea is, therefore, usually considered to be equivalent to an Ammonium-N source.

How to Make Urea Fertilizer Garden Guides
Apply the liquid urea fertilizer to one spot at the outer perimeter of each plant that you wish to feed. Give small plants about 1 pint, medium sized plants 2 pints, and 3 pints for large specimens, until you’ve used up half of the liquid in the 5-gallon bucket. Add more water to the remaining half of the solution to refill the 5-gallon bucket.
To spray or to spread: Quantifying UAN leaf N uptake
Urea is prone to volatilisation because it is highly reactive with water. For plants to utilise nitrogen from urea it must pass through a two stage reaction. 1. The first stage of the process is the conversion of urea [(NH 2) 2 CO], with the addition of water, to ammonium (NH 4 +) as ammonium carbonate. This is called urea hydrolysis.

The amount of nitrogen left is a more difficult question. If you used urea on the soil surface and it did not rain for five days or so, you probably lost some of it to the atmosphere. How much you lost depends on the soil moisture, temperature, wind speed and soil pH when you applied the urea, as well as how long after application it rained.
