Spraying - low pressure

We are doing pretty much everything with 035 guardian airs at 100l/ha. I thought pretty much everyone was at 100l/ha these days but perhaps we are underdoing it slightly?

I have 03 04 and 05 guardian airs. Fungicides at the moment I’m using the 03 @ 100l and upto 3 bar depending on conditions. Did pre em on my maize last week 200l with the 05, as the ground was really dry I wanted to help the chemical as much as I could and get really good coverage. The 05 means I can still spray at 12k.
Use the 04 as a halfway, I like spring Atlantis at about 150l and they are ideal for that without the larger droplets the 05 would produce.

Spraying cereals, currently on red (04) flat fans. Wanting to reduce water volume to around 145-150, at 11k that would mean 2 bar or just over. Should that be ok or is it too low for some things - ie get a set of blue nozzles instead?
Been on 04 Red FF’s for a long while and always looking for a reason to change but can’t find one. We do everything at 200l and 9km/hr which is about 2.7bar iirc.

I mainly run 04 bfs bubble jets, which have much less drift compared to the 04 flat fans I had in previous but they always did a good job and only swapped as they where worn out.
I will usually vary water volume depending on what I’m spraying, conditions an field size as well (unless water rate is critical) but usually go around 170-180l/ha but pre em will go as high as possible especially if it’s dry.
One thing I do like though is it’s a twin line machine so have a set of 02GA’s on the second line which means I can flick between the two for rough headlands or behind houses and gardens ets. It’s also handy for getting good coverage on pre em’s etc as I can run both lines at the same time and knock on without getting excessive drift.

I thought it was only the Facebook hero’s that applied at 100L/ Ha to boast about how many Hectares they can do in a day.
Are you covering a large area to justify 100l /ha
I spray herbicides at 180-200 l
Fungicides at 160
And potatoes at 200-350
All using 04 and 05 s
I tried 100l / ha through 03 s and didn’t like the look of it.
 

Rejuvenating swards: Which option is best?

Written by Brian McDonnell

Maintaining grass quality during mid-season grazing is important. Farmers can maintain quality by entering ideal grazing covers of 1,300 – 1,500kg DM/ha, and grazing down to a residual of 4cm every rotation.

If you are now in a situation where cows are not cleaning out paddocks as well as they should be, leading to the development of steamy grass within the sward, here are some options.

Common options for rejuvenating swards include:

  1. Take a silage cut, probably into bales, remove the material and start again with the aftermath...
