Luckily the US has exposed ourselves to the global gas market.

One big reason for surging fertilizer prices is surging prices of coal and natural gas. The urea in your urine is produced in the liver. The industrial kind is made through a century-old process that uses natural gas or gas derived from coal to produce ammonia, which is then used to synthesize urea.

China and Russia, two of the biggest producers, have restricted exports to ensure supplies for their own farmers. In China’s case, an energy crunch led some areas to ration electricity, which forced fertilizer factories to slash production.

But it's not just for fertilizer any more:

Freight trucks worldwide are starting to be sidelined by a urea shortage. A wide-ranging variety of factors, from rising fertilizer and natural gas prices to an export prohibition, have strained the world’s supply of urea.

Urea is the primary component of the diesel exhaust fluid [DEF] necessary in ensuring that diesel combustion engines function within nitrogen oxide emissions standards across the developed world. A urea-water solution is injected into the exhaust stream of diesel vehicles before the gasses pass through a catalytic converter.

There is a DEF chip on diesels that shut the engine down when DEF runs out.

Oh, about that chip:
Ongoing shortages of replacement parts for failed diesel exhaust fluid quality sensors are believed to be causing thousands of trucks nationwide to be disabled and parked.

The sensors, which measure the quality and level of diesel exhaust fluid (DEF) in the tank, normally retail for roughly $300. But due to global computer chip shortages causing a backlog the part is being offered for sale — in some cases on digital retail sites such as eBay — for as much as $7,000, according to some industry technicians.

“It’s part of the global chip shortage,” Paul Enos, CEO of the Nevada Trucking Association, told Transport Topics. “We’re seeing trucks parked throughout the country. Just here in Nevada, 300 trucks are parked waiting for quality level sensors.”

Enos said there is a fail-safe that’s built into the selective catalytic reduction system of 2010 and newer trucks. “If it senses too much [nitrogen oxide] it will derate the engine,” he said.

EPA is aware of how the global shortage of Diesel Exhaust Fluid (DEF) sensors is impacting vehicle owners, and we are working diligently with manufacturers to support them in providing solutions.

I work in electronics, and this is exactly the sort of shortage that worries me the most. Most people aren't aware of this, but sensors are often specialised equipment that is made just in one place in the world. And there are lots of different specialised sensors. Everybody is aware of places like TSMC and the chips they make are something that if you are in the electronics business, you are keeping an eye on. But nobody, as far as I know, is keeping an eye on the zillion sensors out there. People only keep an eye on the sensors they use, not others. And in many cases, a piece of equipment without a working sensor is useless.
