liquid nitrogen

TheSunderz

i hear of a few farmers around using a form of liquid nitrogen nowadays.a bit more expensive but the results seem better than normal bagged fertilizer. does anyone have any experience with it? cheers

It's good stuff alright, works well and the application is a lot more accurate. You need a decent sprayer to put it out though, and a set of special nozzles. If you're working on grassland you really need GPS on the tractor too, because if you miss a bit you'll see a straight line in the field where the grass got no fertiliser.

allot of faffing about especially when there is little or no cheap distressed nitrogen in this country as we dont make any of the stuff anymore. I dont see the point in melting full price urea so as to apply with a sprayer. Its not as if we are short of rain in Ireland to get the N into the roots. I use foliar N but only to get me out of trouble with spring crops. Probably a few guys are at liquid N it to be talked about:):rolleyes:,

Have you used much of it yourself?

liquid N = never used it,
foliar N = I use a good bit

is there even a supplier of liquid fert in Ireland?

2 guys making it as far as I'm aware, one in Wexford and one in Tipperary. It's a franchise from a Danish company. There's a lot more too it than simply "melting urea". In theory you can use 20% less N and 50% less P due to the chemical composition of the fertiliser. Another advantage is it doesn't leach. I used a 15-2-6 compound myself on wheat and was happy with the results, I know several dairy men who are using liquid fertiliser almost exclusively on both grazing and silage ground. As I said already it's a far more accurate way of applying fertiliser, no overlap on headlands and application rates are accurate to + or - 1% if the sprayer is calibrated properly.

there is F all else to it than having a mixing plant and melting Urea to whatever strengths add a bit of S and bobs your uncle, if you think otherwise its salesman speak. I know of a plant fairly local at it, but they cant source cheap N. As for using it to apply P and K I dont see it as a runner, because by the time you have it in liquid form you have probably doubled the quantity which is nearly the same with liquid N. how much 15-2-6 did you put on the wheat and what was the cost of the liquid? on the accuracy issue it is usually the nut driving the machine which determines how accurate a machine is as fert spreaders can also be set up to give serious accurate results. do you hire your tanks or do you own them?

its the Flex liquid fertiliser that I use but this isnt a liquid N per say

I do think otherwise, for 2 reasons. Number one I see a plant in operation on a regular basis and it's a bit more complicated than that. Number two I've spread somewhere around 1500 acres of it so far this year for numerous people and they're all very happy with the results. And before you ask I don't make it, or sell it, I just spread it. The 15-2-6 cost €340/tonne last year, it comes in 1200L IBC tanks and when the tanks are empty they go back to the man making the fertiliser. The foliar N you're using, I presume N16, is different stuff altogether, as I'm sure you already know.

yeah its N16 or N18 im using in an IBC and its a horse of a different colour to liquid N but I find it good to get spring crops and problems up and running. I assume N16 is N and some molasses which is basically heroine for plants:).

Im talking about making straight N liquid which is pretty simple once you have a bit of water and a stainless mixing plant, but very quickly you get into a bulky product that has to be applied on with a sprayer. Horses for courses I assume. This year was probably ideal for liquid given the weather for the last 2 months.
