Liquid fert and new urea rules ?

The evidence is arguable.
However even DEFRA’s own figures only show Urea applications as around 8% of the problem of ammonia in the atmosphere. Will any inhibitors make much of a difference anyway?
The majority is caused by livestock manure but they are putting all the onus onto manufactured urea. Which is quite suprising really as they usually love regulating the livestock farmers.
 
just use urea before 31 march

this is the recommended timing when it is likely to be dry in april

on heavier land the optimum timeing of nitrogen application is a very wide window so putting it all on in march is an option

imho using a modern spreader we need to test the spread pattern on the headland setting as well as the field setting

There is an ongoing challenge over the liquid piece with Defra but as it stands today, from next year any Urea or Liquids applied between Jan 15th and March 31st do NOT need inhibitor. Anything applied from April 1st through to Jan 14th (Summer/Autumn/Winter) does need to be inhibited.

Liquid is the most flexible as you can take it all without inhibitor and add some into your sprayer in April only if you need it, or we can simply send the later used product out to you with the inhibitor included if you want it to remain simple.

is this actual law now or guideline / RT / cross compliance ?

@Clive there is Limus clear and an Omex version which I can’t remember the name of, both are just added to the sprayer as required when filling.

Although it does surprise me a little bit, given your pursuit of soil health etc, that you’re not using Foliar applied N, there is no requirement for this to be inhibited and even better it is claimed up to 12x more efficient. Joel Williams, Neils Corfield and Graham Sait are just 3 names in the regen world that advocate foliar nutrition.

I'm still to be convinced you can grow big yields on foliar N

Give the price of N and it environmental impact if it was that simple the legal N max would be much lower than it is and we would all have been doing this a long time ago

Lot of often "wishful thinking and half truths" creeping into the regen ag hardcore these days imo - I have been doing this long enough both successfully and unsuccessfully to spot the difference now

from prices I saw today its going to make a £45 /t cost difference to urea

meanwhile in the Ukraine .............. :(

I'd love for someone to tell me how untreated urea applied before January 15th is somehow going to be a volatilisation risk.

Interesting, thanks.

we have a good solid spreader but you can never beat the 100% to the line cut off of a boom

with average field size small we have a lot of headland area - this will effect yield and be worse for environment IMO. yet another classic case of fixing one issue whilst making another worse !
Is it fixing anything or just Minnette doing CF's bidding?

Don't forget any regulation like that would be strongly opposed by Minnie's non farming members. Food security blah bla blah...

120kgs of liquid N before the April deadline, soil applied (Advice from those like Joel-But not Joel himself-suggest that as the soil is cool, the soil biological activity is low & there will be no significant detrimental effect, and may even serve to 'wake up the biology a bit earlier - A bit like the effect that I seem to have repeatedly seen with grazing cover or combinable crops early (jan/Feb/March) & all the pee and poo that comes with that).
Foliar N thereafter, with nutrition and if you like, fungicides.....Using Brix. Has worked well for a couple of years, but i'm not hard and fast on it across the whole acreage. Haven't seen any statistically significant difference in yields between doing it this way, and conventional soil applied across 3-4 splits to a total of 220-240kgs.....But still too chicken to roll it out across a wider area, and on contracted farms.....No two years are the same etc.
Pretty pee'd off with the conversation about this a couple of months ago with the fert rep - Whom i have a lot of time for. Apparently it will come separately to the liquid fert, so added to the tank when legally required (As others have mentioned). May well push me to do more area with the 120kgs soil, the rest foliar.

What's your total n after the 120kg soil applied?
