The decomposition of urea [(NH2)2CO] produces two equivalents of ammonia for each equivalent of urea. It's not clear from the article how much (if any) of the ammonia gets consumed by the bacteria.
> Is large amounts of ammonia easier to dispose of than urea?
Ammonia's boiling point is -33 C, so pure urea is a gas a room temperature.
When dissolved in water, ammonia is in equilibrium with ammonium hydroxide. So the stuff can stick around until consumed by microorganism or it evaporates.

Both urea and ammonia can be used as fertilizers.
