Is there any difference between urea and all nitrogen fertilizer?

Whenever I look at urea, I always see it with a high nitrogen count, but none of anything else. Does that mean urea and nitrogen are the same thing?

1. Urea fertilizers are usually a quick shot of nitrogen. High nitrogen lawn fertilizers are usually slow release (or should be), releasing the nitrogen over a few months. -Brian
2. it still would have other elements even if small
3. Urea is one of the purest - strongest form of nitrogen you can get for your lawns. Be careful in the summer months as it can burn the lawn if not watered enough or put on to heavy..
4. urea is (NH2)2CO; it hydrolyzes to ammonia and carbon dioxide in the soil...the other nitrogen carrying fertilizer is ammonium nitrate NH4NO3...thus both are about 1/3 nitrogen by atomic weight...other fertilizer combinations also carry nitrogen, such as potassium nitrate or ammonium phosphate... the ammonium portion of nitrogen fertilizers evaporates with excess water, and the nitrate moves with water to lower in the soil profile; that's why one must side dress plants with nitrogen fertilizers during the growing season
