Who has used Liqui-safe or Limus type products? Any feedback on costs and how the crops performed?
Liquid fert urease inhibitors

Used them both for the last 2 years. Hard to say if it made a difference , tried split fields with and without, tried lower doses with against normal dose without, hard to see a yield difference, maybe the yield meter isn't sensitive enough! I did see a colour difference though. I'm going to use limus in 2023 as its the cheapest option, this is in uan +s liquid fertiliser.

I used liquid for a number of years and tried various products. Ended up taking the money used for the inhibitors and put it towards extra N and called it quits. Timing of application was more reliable. Ie when rain was coming.

Yet to see any independent evidence that they improve N uptake / can use less N for same yield.

Think this will end up like ad blue , we will be forced to use it but just keeps people happy , whilst not really solving the problem.

How does anyone know if you have used an inhibitor or not?
An inspector would want to see invoices or delivery notes for it.
That's not really the driver for these additives. It's all about reducing ammonia volatilisation (and possible nitrate leaching?).
At our expense, and by reducing competition from the global commodity that is urea.

Yep. But they keep telling us we will get better uptake etc etc etc as a way of justifying their products.
Looks like they will bring in a cut of date each year where after this date you have to use an inhibitor. Where I farm volatilisation isn’t really an issue as soil temps are too low when applying urea anyway.

I know, but it would be a bit of good evidence for us skeptics that significant N was retained.

Which inspector is this?
RPA or more likely, Red Tractor. That's just in theory - the Farming Rules for Water and the urea restrictions proposals were kicked down the road when the government quite rightly focused on more pressing problems like sovereign debt, the energy crisis etc but these have not gone away.
NIAB TAG did a long term (multi year) trial on yields using the same kg/ha of N using untreated urea, UAN and ammonium nitrate. There was no significant yield difference between any of them. Slightly lower grain protein levels with urea, that’s all.
The narrative about urea’s GHG contribution is driven by dodgy data and vested interests in the AN industry who want to reduce the competition from lower profit margin urea

Is it about GHGs? I thought ammonia was blamed for air quality, because of trapping particulates, and HM government had to do something because they lost a court case.
Ammonia is a short lived GHG.
Is this the court case you are referring to? https://www.theguardian.com/environment/2018/feb/21/high-court-rules-uk-air-pollution-plans-unlawful
