What's happening here is a market problem: ammonia fertilizer is way more profitable to sell (due to high demand and low elasticity of demand) than carbon dioxide, and they come from the same feedstocks, so chemical producers make it instead. Lower supply -> price goes up -> consumers don't want to pay high prices -> effective shortage -> articles like the OP.

There is literally no known chemistry that would practically be able to deplete the trillions of cubic meters of air over Europe of carbon dioxide. Please read up on atmospheric physics so you can understand why some contrails persist while others, at different altitudes, disappear almost instantaneously. Don't bother replying to me, either, as I have flagged you as a troll.
