Foliar nitrogen feeds

[snipe]

Anybody used these before, Agri have one and 20litres/ha is 40kg/ha. Equivalent to around £400/ton fert price..

 

[Jack Russell]

Surely that should be 4kg/ha from 20lt?

 

[robbie]

What's the product called????

According to the guy I was speaking to a few months back (from another company), if you allow for the fact that granular fertiliser is only 50% efficient, AND their foliar products are 6-8x more efficiently utilised, then you can come up with some spectacular ‘comparative’ figures.
That one put there product at roughly the equivalent of buying AN at £300/t (which I’d just done at the time, purely coincidentally)

I’ve seen a ibc arrive in a friends yard that I spray. He did say some numbers about how more efficient it will be but I was too busy thinking how many bucket fulls I’ll have to tip in each tank next spring to let the figures sink in my tiny brain.

Probably be a methylated urea product. 20L/Ha will give about 7kgN but with uptake efficiency it will give equivalent to 40 out of the bag.
Make sure you know which product you’re buying - some have different ratios of methylated urea to urea, and different uptake periods and longevity - they aren’t all the same. A cheaper product may not give the same result

I should perhaps admit that I did end up using a 205L drum of Amine Nitrogen as a late N application on 7ha fodder beet. As it was waist high, and tramlines more or less filled in, a folia application with an SP on rowcrops made more sense than trying to spread AN.

The crop has certainly taken it in and responded well, but the degree is obviously anyone’s guess.

Busy drilling round poles at the time when on the phone so not a100% sure. Think it was nitro boost. .

 

[Flatlander]

It’s called bullsh1t.

A company here has been selling ortho phosphate say it you only need a few gallons an acre to supply a crop with enough yield well. It turns out that yields were similar fir two to three years then have tracked lower at the soil reserves have been mined out. Being efficient was one word they used. call me sceptical but it seems to good to be true. Any independent trials ?

A bit of information I was sent.

 

[Oldmacdonald]

Would normal urea based liquid fertiliser not do exactly the same?

 

[Nowthenblue]

Lost any credibility at Kg/acre of AN.... really ???

Exactly it should have been units/AC!!!!!

 

[Salopian_Will]

I've bought an IBC to try. I am open minded on it at the moment. We need to improve our N use efficiency and if this is a possible route then it is worth trying.

Taken from CPM Magazine May 2020 ...

Spring barley trials by the manufacturer of N-Durance 28 have shown that 40 kg N/ha of conventional ammonium nitrate granular fertiliser can be replaced with 7 kg/ha of N-Durance 28 when applied at Growth Stage 39, with no reduction in yield (in a programme using 100 kg N/ha AN in total). A yield benefit over the standard 140 kg N/ha AN has also been found when applied at the earlier GS 30 timing.

It may well do, a few litres of 20% urea liquid added to the sprayer tank every time through the crop between April and May, may achieve the same thing.

£2700 for an ibc , 2700/125=£21.6 . mmm, for an effect that may or may not happen.

I think I would play around with a bit of melted urea.

Mix safe?

 

[Fish]

Mix safe?

Don’t see any reason why not,
20l in 200, or you could do it as a separate pass.

I think I might try playing with some adblue this spring on a trail plot.
Addblu 14%N so I was thinking 20 Lt/ha a pass.
