Anyone using a bagged product

What type of application rate and frequency ?

In water though right with spray? I do 5kgs at T2

Yes sorry only way I know of applying it

Best way of applying it too.

As above. Lots of it. Some liquid Mg formulations are dissolved mag sulphate & selling expensive water!

kieserite as per recommendations from soil test

That too but leaf analysis always short I’m wondering should I be using more or each pass rather than later in season

I think you are likely right

We are on chalk or otherwise high Ca. Every spring pass in cereals & OSR.

At 5 kgs? Wow you must get well cheesed off filling the sprayer. Obviously you think its worthwhile?

It's quicker chucking a few bags I find than out of a 200l barrel tap.

How? Serious question? Or does your sprayer suck harder than mine. Takes ages to suck up 25kgs here

What are your Mg soil indices? Nitrate or sulphate? Any tissue tests? Forgive the questions but I am also on chalk but leave the Mg until T2&3 because I’m using Mn, Cu or B with earlier sprays. All have showed up as low with tissue tests.

I hate humping bittersalz into induction hopper. Must handle tons of it in summer for final spray on spring barley.

We just buy it in a ibc.

Takes seconds to fill a 10l bucket.

Same here, I've been doing lots of tissue sampling over the last few seasons and I've got my cu,zn,b,mn right mg is the last to sort. I've been using mag nitrate out of a ibc for t1,t2,t3 on all cereals and osr at 3 lt and I think that's whereby need to be the only thing else to do is an early spring t0ish application when I go through with MN.

Soil indices here mg o-1 and ph from 7.5 to 8.5.

where doe's everyone get their tissue tests done?

Can’t you build your Mg indices at all? We have a bit by using kieserite with all PK applications. We would be 1-2 Mg mostly
