Urea Stewardship

[Plough on]

Can someone just explain how this would be used?....

Untreated liquid UAN fertiliser can be applied after 1st April if agronomic justification is provided by a FACTS qualified advisor that demonstrates ammonia losses will be at or below the level of including a urease inhibitor.

Is anyone else miffed or is it just me that none of the fertiliser companies or agronomists have been keeping us up to date with this?

In theory someone with the FACTS qualification is able to assess the current weather, temperatures, soil type, etc and judge that the risk of volatilisation is low enough to warrant the use of liquid UAN fertilisers. If your current supplier of liquid fertiliser is not willing to do this then I would want a very valid reason as why not. If you are unhappy with your supplier of fertiliser then buy from elsewhere another season.

I don't think many FACTS qualified advisors will be willing to put their neck on the block, so your only option is to add an inhibitor (or flaunt the crazy rule). About £4/ha for the liquid I am using (last application of 3). More concerned about the scorch risk to be honest.

It is indeed irksome if you have solid fertiliser in store and have not been able apply it due to ground conditions and now cannot apply it.

However, as you can add inhibitor to liquid material why not just add the inhibitor and be done with it? The inhibitor has a cost but the improved nutrient efficiency should cover this.

To meet the same level of nitrogen reduction as for treated solid urea there would have to be soil incorporation or irrigation or both (or good luck with the weather). I have not seen any guidelines for these factors so would find it hard to be sure 'ammonia losses will be at or below the level of including a urease inhibitor'

Why the 31 March was on Q I that spring takes 2 months to get from the. South of UK to the North.

Oh forgot there is no North

The problem with inhibitor is that it will take 10 days longer for the n to be available may be longer at current soil temperature fore cast to get down to 5c with an air temp of 2 c

Are you saying the inhibitor is cost affective and volatisation is a real thing in this country.

Means this whole debate about treated v untreated is pointless?

But despite the fact that they are not willing to to put their neck on the block, the merchants are more than happy to tell their FACTS qualified advisors to instruct those of us that weren’t able get our Non Inhibitor treated Urea applied prior to 1st April TO LIE on our record sheets!

It comes to something when we are TOLD TO LIE, doesn’t it?
WTF!

This begs a couple of questions:

Does the inhibitor reduce or slow down any alleged Volatilisation?
Hence the longer time it takes for the Nitrogen to work.

With temperature so low at night as they were last night, surely this naturally slows down the speed Urea works anyway, so the risk of alleged Volatilisation is reduced anyway, which any FACTS advisor ought to be able to provide a derogation for?


………Irrespective of the fact that it doesn’t matter a feck what happens in Northern Ireland, Scotland and Wales, because Volatilisation doesn’t happen in those Countries anyway!

No different to a lot of stuff for the great Red Tractor.
