Depends how much confidence you have in the AN manufacturer's 'independent' trial work on volatility. Most of the world uses urea only, and a lot of that is an awful lot hotter and drier than the UK (especially NI).
But most are still very careful about application timings. Immanent rain, or at least moist soil, is still an important consideration.
That said, even out here in South Australia they don't consider it a problem below about 28 degrees. I think one study even ventured that it was safe up to 32 degrees.
Either way, I doubt you'll have an issue where you are at this time of year, so crack on!
Is there any golden rules to the timing of Urea application.
Put a first dressing on grass end feb 40 units, same again end march,cut around 15 th May.
sorry my grammer was never a strong pointYou must be ahead of us! It's not the end of March yet, never mind May

Thanks folks, 1st year to use Urea, 50kg per acre on now, old folk believed it to be sore on land but fed up with poor results from compond sowed in April.
What would be the rule of thumb be when applying urea in Aus. When and when to use something else.
