Boron and foliar K on cereals

Anyone done this, tissue test showing deficiency on both along with zinc. This is on a field of rye which is entered in YEN. Not into luck and mystery stuff so it's getting a dose of Yara gramitrel with first spray but I could add some boron as well but not sure about foliar K

Tried boron on spring barley last year, no difference in crops.

Has Gramitrel got K, B & Z in it? If not I would question why are you putting X on after a tissue that shows it is short of Y. K is mainly taken up by roots? Although having said that there is some evidence to suggest a small amount of foliage K can stimulate the plant into more uptake from soil.

Last year's tissue tests done here showed similar deficiencies. You've only shown what was the state of the plant at that moment in time. K will always show as low during rapid vegetative growth. If you're running this for YEN, I'd chuck plenty of the products you mentioned in just to cover any transient deficiencies. Pile the K on - the plant needs plenty.

Edit: if this was a more commercial crop instead of a YEN one, I'd be less keen on chucking lots of foliar nutrients on.

Gramitrel is good stuff and I would echo the above.

Likely you are short of mg and boron. A few here going with 1l/ha boron per pass on cereals.

Gramitrel has Mg, MN, zn cu iirc. Hoping that a good dose of lots of traces will also help with disease. Any thoughts on that?

Id say buy them all separately and mix and match as required. Gramitrel is a good product but you do pay a premium. With straights you can apply a mix now and then re test and tailed the next mix you what is needed.

Regards disease good nutrition is definitely a way of reducing fungicide spend but it's more than just a quick squirt to get to to work the you need to start with the soil and build from there.

Boron is toxic to cereals. if your analysis shows a very low level of boron, that's enough.

Obviously the rape market for boron is failing at the moment.

Edit: sorry, it's YEN. Yeah, chuck it all on, let's get those 20 t/ha! And don't forget the lithium, caesium, mendelevium, and polonium!

How much boron do we need? Previous tissue tests show low B in wheat & osr. It is still a nutrient even if the plant doesn't need much.

Use a mix, home made or branded product that way the plant takes what it needs and you do not end up creating an artificial deficiency by overloading one element. Ref work in Germany on OSR 5t/ha crops.
I would always include zinc as it has the greatest effect on ear size if you get the timing correct.

So what is the correct time ?

You are trying to influence ear size so it is early especially calendar wise relative to WB
