Also in our hard water areas 100l gives better performance for a lot of products due to less cation lock up.

Thanks. Did you try 02s and have problems? With hard water I want to keep water volumes down for a lot of products. Would it work using the 03 nozzles at 50cm at the same time to get higher volumes where needed (although obviously couldn't do lower boom heights)?
Treating your water would be a better investment.

We already do. Have had water tested so we know accurately how much X Change to use. Just don't see good evidence for higher water rates so may as well do nearly everything at 100l. More sprayer output obviously too.

100lts/ha and water conditioner
We stoped using 25 cm height for most things - there is just no need it’s so good at 50 and x2 or x3 the nozzles / m we used to have - a real 50 all the way across the boom is remarkably low - Much lower than what you used to think 50cm was !
80deg choices are just too restrictive

That's what we do. 100 l/ha plus 0.18l X-Change.

I really am not expecting to give up on that advantage. It's part of the reason we got the thing. 56% reduction in drift from 50cm height down to 30cm is not to be sniffed at. Can't see what the problem is with yellow 02 80 degree flat fans? What was the point in spec'ing 25cm nozzle spacing if all you do is spray at 50cm?
I believe you get higher droplet speeds (and IIRC a lower range of droplet speeds too) with 80 degree nozzles compared to 110 degree ones. This is gives, to use an advanced driving phrase, a lower TED (Time Exposed to Danger) in addition to the reduced distance to the target.

Wait until you use it a bit - I bet you change your mind !
The reason why 25cm is still an advantage at 50cm is that you can have twice (or even x3) the nozzles applying the same volume - the additional coverage that gives is remarkable and at a true 50cm height drift just isn’t an issue with the guardian air - flat fats are great but can be drifty
What I planned is not what we have ended up doing it’s such a game changing bit of kit
Still trying different combos however and remember I don’t use pre ems here, never spray bare soil, and don’t have black grass so maybe different priorities to you

No not really. At 150l/ha I can do 40ha on a tankful with a decent forward speed
I spray at 35-40cm above target and drift is minimal compared to 50-60cm. If you set the boom to lift 30-50cm at the end it is really noticeable when starting a run if windy till the boom gets down to work height
Flat fan 80degree nozzles. Why bother with any of these low drift nozzles when the whole boom is low drift, used as intended. Oh, and I have alternate nozzles pointing forward, meaning I cannot use the front space as it hits the alloy curtain
Only use the 50cm spacing for fertiliser nozzles

Applying liquid Fert was a real eye opener.
06 at low speed, 10 as you speed up, both if you go really fast or large dose
The novelty of that still hasn't worn off after 3 seasons

And are you happy with the 06 and 10 combination?

So would you say that 80 degree flat fans at 30cm will be less drifty than something like a Guardian Air at 50cm? I was wondering about putting only backwards facing Defy nozzles on at 50cm for higher forward speed spraying with the backwards facing element of the nozzles doing that bit extra to counteract the forward speed to get a bit more penetration down into the crop. Not sure if that is a mad idea or not.
Also, any suggestions on the best flat fan choice? I guess an XR type one that can handle a wide range of pressures?

I have gone for 580s (that's actual tyre width measured with a tape measure) on 36m. Will see how it goes and am prepared to get row crops. For us it's a heavy sprayer and I don't like the idea of really high pressures mainly for my back and slightly the field.

No. I'm saying I just wouldn't suggest any LD nozzle when 25cm spacing, lower boom height, the front curtain, 80deg nozzles all do the same job whilst still allowing a fine spray therefore good coverage of the target.
All air inclusion/LD nozzles end up compromising coverage because of the larger droplet size. When my sprayer was new we did some tests on different nozzles and settled on flat fan 025 80deg alternate forward and down. With a little assistance from my agronomist

That's what I did. I instantly regretted it over wider winter tyres and narrow row crops.
However time tells me it probably is a good compromise. Very little winter rutting and you wouldn't get away with much narrower to still be safe at 50k in the summer
If I was buying new again I would probably stick with the 580

It was my first real use of liquid Fert so I'm no expert. I'm happy as it covers all speeds and rates that I would use.
Maybe others are more experienced on liquid fertiliser than me. @Clive
