I would not apply liquid N to a frozen OSR leaf myself,esp if I was expecting a follow up frost as well.

What about a wheat one?
I would not personally but it would always be scorchier if you have anything other than straight urea in the tank IMO. I would ask Simon @BFSfertilisers his view with the liquid you are using.
I have mixed some N18 and some N25/12S so have a choice if i had to get out there now for some reason. The spinner makes more sense [on the frost] to me.

I would not apply to frosted leaves as the idea with liquids is to get the droplets to roll off onto the ground, and a fully waxed dry leaf facilitates this. Frost will absorb a significant amount of the fertiliser, and when that dries there can be a high concentration on the leaf surface, resulting in scorch.This can then be made worse by following hard frosts, where the wax cuticle has been damaged. We sometimes find this happens with dewey leaves that do not allow the fertiliser to completely run off. You do see the same effect with granules, where they have lodged onto wet foliage or got trapped in the leaf axils.
Its a matter of "do I need to get out there today" because timing is an issue, and if that's a yes then do expect to see damage. In the early spring this may not cause a long term problem as most of the leaves present will be sloughed off anyway, and the fertiliser stimulates quick regrowth.
Hope this helps.

has anyone considered a boom type solid fert applicator, often wondered about one myself Kuhn aero or something? are they any good? seems to me to be a compromise? accurate spreading but with solid, can buy cheap urea sulphur and still spread the width?
suppose the argument will be still have to haul bags out to field to get a lot done? but could go when windy/rainy more?

Off topic a little, sorry. Id like to know the ingredients for the N25/12S.
Thanks S

We used to/still do run a kongskilde wingjet 24m trailer applicator. The theory is right but in practice the machine is fairly un reliable and not very accurate. This year we are trying to switch to 100% homemade liquid and work our sprayer harder. Will see how it goes.

why not accurate? the metering unit? I would of expected near seed drill accuracy as it could be calibrated similarly?

We just feel that it hasn't really been designed for big farms with big output in mind. Regarding the metering quite often you will set a rate of say 200kg/ha and get to the end of the field and be 20%out! Also the clutches controlling the sections are pretty un reliable and we will have days when we can't switch the end section off one of the booms obv causing overlap issues. The booms need a lot of tlc and a sympathetic operator. Electrics are appalling! In mud the drive wheel slips and won't meter product out.
Having said all that when it's working properly it's great and we can use prilled urea spread to 24m in wind/frost etc ...

This is why I am doing it, watching these threads very closely. Am going to be all liquid N so straight in at the deep end.

A frost is about the only weather you can’t go in. Sun up to 18 degrees is fine, cross winds up to 20km/hr are fine on the day but not the day after if the winds are prolonged as that dewaxes the leaves as well and obviously any amount of rain is fine.

Hello all, new to this so bear with me, am keen to try liquid urea this year but very confused about it all. Hardi twin force sprayer, generally use brown 05 nozzles, if I got 05 fert nozzles, will the rate controller be accurate given the heavier liquid or will it need to be recalibrated? Why do some people say that you need adjustable dribble bars for different rates, surely you just up or lower the pressure as with regular nozzles or am I taking it up wrong?? Regarding scorch, normally I would avoid spraying chems when leaf is wet to avoid runoff so why do some say not to apply fert to wet leaf when you are trying to get runoff? Sorry to be so thick

Someone will be along soon to answer a few of your questions, it is a bit more complicated than just upping and lowering pressures.
I would suggest for now to get some more research in, next to the seach box in the top right of the screen is a magnifying glass, clicking that will drop down a box with more detailed search options. In the bottom box is a Google powered search, search for 'liquid fertiliser' in that box and you will get pages of results that you will be reading for days that will cover most of what you want, couple here for starters;

Liquid fert is obviously a more accurate way to apply fert, but on this farm for the first dose we will travel better/sooner with a tractor and spreader on broad tyres than with a sprayer early on in the season.
Second dose the sprayer seems busy enough, 3rd dose there is the risk of scorching, also urea is cheaper form of N. Unless well set up with a liquid mixing plant and mix your own up, so more time and investment.
Not saying it’s right every year but we are going all solid this year.
