Foliar nitrogen feeds

But it is replaceing a smaller quantity of bagged fert in the programme unless you are targeting protein when it would be in addition. Just not a complete substitute...right?

Yes it’s replacing the later applications after an initial yield building dose of AN or Urea bagged product.

Some work I saw was creating full cover with early AN/Urea dose, then replacing subsequent solid applications with the 5:1 substitution thereafter.

So for example' Total dose 220kgN; start 100kg as solid, then 40, 40, 40 solid, or 40, 40, 8KgN as form urea(equiv to 40 normal), and the other options until you get 100kgN as standard fert, then 24kgN replacing 120 kgN as standard fert.

This 24kgN formaldehyde urea is supplied by 80L/ha over the 3 splits

Pretty sure you need decent GAI before you start so building blocks of biomass are there.


And no I am not in any way advertising it.

Some helpful information was sent to NIAB tag members on this subject this week.

Is this going to turn into the Triton Drill/Amino A thread??
Plenty of unscientific, uncorroborated, statistically insignificant, pick and choose, trials coming our way I suspect.

There is some independent science on this.

For arguments sake then, 30kg of n durance type long chain foliar n will equate to 60kg bagged n if you allow for 60% efficiency

Was intended to go through osr with 20l of one of these n28 products this week post flowering. Meant to add around 0.2/ 0.3 t per Ha to yield by keeping the crop greener for longer. At current prices a 0.2t/ ha increase will give a 4 to 1 payback.
I've already applied 200kg bagged N though. Will I be wasting my time and Money? Crop looks decent but I wouldn't say its record breaking.

Considering doing similar, 50 litres of 20% nufol to give 10kg of N

Mine has had considerably less so far though, however brassicas like a bit of N.
