    Urea is a synthetic form of nitrogen. It is not a natural product. Not sure what the exact chemical make up is.

    Urea is made up of...

    2 Nitrogen atoms
    4 Hydrogen atoms
    1 Carbon atom
    1 Oxygen atom
    That are all stuck together

    AKA... (NH2)2CO

    It can be manufactured synthetically or biologically. The stuff you buy is synthetic.. the stuff you pee is biological.

    After being manufactured, you really can't tell the difference.. a molecule is a molecule... usually.

    Hey JD a couple interesting things from wiki

    Urea is used as a nitrogen-release fertilizer, as it hydrolyses back to ammonia and carbon dioxide, but its most common impurity, biuret, must be present at less than 2%, as it impairs plant growth. It is also used in many multi-component solid fertilizer formulations. Its action of nitrogen release is due to the conditions favouring the reagent side of the equilibria, which produce urea. If the group of bacteria which "burn" or oxidize urea are not present in the soil then most of the acting ingredient (nitrogen) will not be absorbed by the plants.

    An additive ingredient in cigarettes, designed to enhance flavour

    A browning agent in factory-produced pretzels

    An ingredient in many tooth whitening products

    Urea is commercially produced from two raw materials, ammonia, and carbon dioxide. Large quantities of carbon dioxide are produced during the manufacture of ammonia from coal or from hydrocarbons such as natural gas and petroleum-derived raw materials. This allows direct synthesis of urea from these raw materials.

    I heard an add today on the radio for a woman's wrinkle cream that had urea in it.

    Thats how compost tea was invented. The old farmers used to squeeze the horse/cow urine out from the poo pies then water with it!

    No joke I saw my grandpa do it with my own two eyes when I was a kid.
