BFS auto streamers are great, no messing about with disc etc, accurate and never had any scortch using them - 5 years out of our first set now and a LOT of acres, never broken one on a Bateman Contour boom

Seems like this is the way to go. Now I just need to find a decent used sprayer. Think I will stick with trailed, probably look at 4000l with 36m boom. Need to have a think about tank siting and bowser.

I have been using liquid N for 15 years - would agree with what has been said about logistics and accuracy - compared to a basic spinner you can be far more accurate both on rates and placement. Be aware that the application cutoff line will be obvious if your tramlines are not accurate (I have sometimes had a double dosed strip between bouts) and tapered garings at ends will either be double or nothing - there is no feathering effect that you get with a spinner. I have always used dribble bars (BFS and Chafer) - just be careful about breakage as they can hang below the boom - have had few problems with scorch.
Another advantage is zero wastage - you don't have the problem of where to put the last half bag at the end of the field - it can be pumped straight into the storage tank
I wouldn't worry about corrosion - my old Gem sprayer looks much the same for rust now as 10 years ago - I do wash it, but not obsessively!
Some years it can be expensive relative to urea - with an owned tank you are not obliged to use it every year if the price is wrong.

just seen this old post. will your Gem (fibreglass tank) take a full load of liquid fert.

Your issue, in this question, is surely regarding frost on a leaf? In which case, and all other things being equal (I.e. no wind, rain or sun issues), it is the same as having dew on the leaf with a generally dry day following.....? I’m led to believe that this is a high scorch risk situation, due to the fert effectively melting the frost and covering the leaf very nicely with a uniform layer of N. As the day draws on, the water will evaporate from the leaf, leaving the liquid fert to burn the hell out of the leaf......? But I stand to be corrected. Do I get negative points for a wrong answer?

I rather suspect you may be spot on the money. Was hoping liquid would allow us to get on earlier. Still have solid for the OSR so will be able to do that perhaps this week if it freezes hard enough.
