Urea is a petrochemical.

Urea is produced from ammonia and carbon dioxide. Ammonia in turn is produced from hydrogen, from natural gas or crude oil off-gases created during the refining process - at least since the 1908 Haber process was invented -, and combined with nitrogen extracted from the air through compression and separation.

So in this way farmers using Urea for fertilizer are competing with other users of natural gas and crude oil, whether this is feedstock for plastics or an electric power plant, gasoline or diesel fuel, or urea for clean diesel combustion.

Ammonia plants are easy to construct, so there's no bottleneck. It would primarily mean that retail diesel stations need to install urea dispensers as you find in Europe.
