Field efficiency tends to drop quite dramatically when you are in 5 ha fields unfortunately 😂

I was being quite generous with the field efficiency I thought - it would generally be higher when using a water / mixing truck

5 ha fields - I’d have thought 36 m would be more trouble than it’s worth 😮

Used to spray at 24km/h at 50 litres ha in Oz, with a Spra Coupe. Forward momentum pushed the spray down into crops
Yes but spraying a crop out there that would most likely get ripped up in this country is a very different proposition to spraying a dense 12t/ha European crop. The guardian air nozzle was designed with a backward angle to take some of the forward speed of the sprayer out of the droplet to achieve a vertical drop to reach into the crop canopy. Excessive forward speed is just going to make things worse; not better.

Was spraying cotton 😉

At 16k you’re creating your own wind 😉 you’ll be surprised how much spray gets ‘sucked’ under behind the sprayer itself and messes the pattern up. Thing in CPM a few months ago and I think that only went up to 12k.
And yet there’s no visible effect in the crop across the boom width at any point in the growing season, be it in disease, weed kill, leaf area index / NDVI, standing power or yield.
I’d suggest that having to spray at slow speed is the new ‘old wives tale’.

Thinking of going back to 24m from 36m. My boom height control system on my 36m is woeful and needs a big upgrade which is huge money so I’m thinking of going back to 24m which would also allow me to go back to granular fert instead of liquid (I’ve posted a thread on that in the cropping section). I could do away with the big heavy trailed setup and get into a lightweight agri buggy type sprayer for not much more money than my decent trailed is worth.
The best output I've ever had was a cleanacres airtec on MB1100, 2000l tank and 24m boom. Apparently things have come on... but with a piddly 3 piston pump and no gimmicks, bowsers or mixer tanks that old girl bashed out 670 acres one day and nothing would tread lighter back then. Just do it.
