Trace elements.

I've had some spray recommendations for spring triticale and barley. Both to be sprayed in about ten day and there is both mg and mn sulphates as the crop is deficent. What sort of rates do you need to put deficences right?

How long is piece of string. Try 5kgs epsotop and 3lit mnso4 liquid. Not expensive. Under £2/ha each.

I keep looking at liquid mag oxide as opposed to epsotop. Supposedly better availability. Any one using liquid mag?

Yes. 2nd season using magnesium sulphate. Buy a ibc at a time. 72p per litre.

Manganese is a fair bit cheaper buy buy it in ibc too.

Mag nitrate in the IBC surely?

Why wait 10 days if the crop is already deficient???

As already stated 5 kg epso top and 3 lt liquid mn or if deficiency is bad this could be swapped for 32% powder up to 5 kg/ha or a mix of the two.

I've used magnesium nitrate from ibcs in the past and now just use bags of bitter salts I couldn't see how the liquid was any better. A kg of bitter salts has twice the nutrient content of liquid for half the price.

If your agro has send you any products other than straight 15% liquid/25kg bags 32% or run of the mill magnesium then get the vaseline out because hell be getting ready to shaft you.

Yeh it’s mag nitrate that people speak about better uptake. FMC and Yara both to Mag Oxide which they claim had more mag than sulphate.

The only reason I can think would be to take advantage of any wetters in the rest of the brew to get the trace elements into the leaf.
I sprayed some straight bittersaltz on Friday night* on to some wheat to see if it would change it to the correct shade of green, and was wondering if it would go in, or just form crystals on the surface - It's still looking a bit pale ?
[*- it had 2L of MnSO4 at T1 a few days prior, and 5kg/ha of home melted SoP in the mix too. Now thinking it's just N taking it's time after the 'drought']

I'll check. Wouldn't be first time I got mixed up!

Ours is from agrii. Personally I hate bittersalz from a fat lazy person point of view. Feels like I tip tons of the bloody stuff into sprayer every year.

You mentioned before and I spoke to Agrii last year but there was some issue getting it or something at that point. Had a long chat with my agronomist last week and he was going to come back with prices for the Mag oxide stuff per ha compared to epsotop.

 

[Sandy]

Is there much point spraying on mag now it’s during grain fill it’s used in the plant?

I think Mg can be stored unlike Mn but I could well be wrong.,

 

[robbie]

Mag is very important for photosynthesis and and that is at its greatest during grain fill.

 

[Chae1]

We don't put any Mg on with first spray on spring barley. Have been using it on winter barley.

Been spraying a mix mg and mn on drought stressed spring barley fields to try and keep them going.

I know it all adds up but I'm putting in trace elements at every pass. On our light land I'm glad of any nutrients I can get into plant. It's currently 3 degrees with light flurries of snow with a 30mph wind blowing down from the artic.

As @ajd132 said I feel we are at the stage where we are growing crops like hydroponics. The soil is just a medium, and feeding plants through leaf and artificial fertiliser next to roots. Not a good situation I know.

 

[snarling bee]

I use Root 66 which is a liquid formulation of Mn and Mg early and mid season. At T2 I usually add Epsotop.
Too lazy to use Epsotop all spring, especially with big enough tankmixes already.

 

[Brisel]

15% Mag nitrate IBC from Omex 65 p/l. 15% Manganese sulphate 48 p/l IBC

 

[robbie]

Manganese in every spray pass and 5 kg epsom salts in the tank with every spring pass.
From a sprayer filling point of view I prefer bags to liquid my sprayer will take bags of epsom as quickly as I can poor them in, have a knife to hand cut the top tip and gone its quicker than filling a bucket from a ibc.
