[QUOTE="Shutesy, post: 5954988, member: 316"] Trying out liquid fert this year alongside our usual solid. Got a spare space on my rotating nozzle holders on the sprayer so going to go with the fert nozzle route rather than dribble bars. Having read just about every thread on here I've decided to go with Hardi Quintastreams which seem to be a popular choice. However I'm struggling to get my head round exactly which colour nozzle I need due to the differences in SG between water and fert and want to get some second opinions. We have Omex 24N + 7.5 SO3 which is 1.26 SG and I want to apply it at 200l/ha (250kg/ha) Our Berthoud sprayer is pressure sensor based (does this make a difference) so I believe I just enter the SG into the control screen and the sprayer will adjust the pressure up for the higher SG compared to water. We haven't got a massive acreage to cover so I don't need to be doing 15kph, 10kph is probably plenty IMO. I assume I need to be keeping the pressure at about 1-2 Bar to try and avoid atomisation and scorch? Below is the Hardi quintastream selection chart, currently I think I need an 06 Grey nozzle? 204lpm @ 10kph @1.5Bar? [ATTACH=full]764610[/ATTACH] Cheers! [/QUOTE]
