81
Even though damage caused by cauterisa-
tion is almost completely prevented, one
should not use 3-jet spray nozzles for late
top dressing, but use towed hoses instead.
Only use the black bayonet nuts for all the fol-
lowing 3-jet nozzles.
Various 3-jet nozzles and their fields of applica -
tion (at 8 km/h)
3-jet yellow 50 - 80 l/ha (AHL)
3-jet red 80 - 126 l/ha (AHL)
3-jet blue 115 - 180 l/ha (AHL)
3-jet white 155 - 267 l/ha (AHL)
CAUTION
Solution running out!
Apply appropriate protective measures.
Catch running out solution in a suitable
container and dispose of.
4.10 Operation with liquid
fertiliser
At present there are mainly two different types
of liquid fertiliser available:
¾
Ammonium nitrate - carbonyl diamide solution
(AHL) with 28 kg N per 100 kg AHL.
¾
A NP-solution 10-34-0 with 10 kg N and 34 kg
P
2
O
5
per 100 kg NP-solution.
When using flat jet nozzles you must multiply
the corresponding values for the application
quantity (l/ha) from the spraying table with 0.88
for AHL and 0.85 for NP-solution. The listed ap-
plication quantities (l/ha) only apply for water.
The following is generally valid:
Apply liquid fertiliser in the form of coarse drops,
to prevent cauterisation of plants. Too large
drops will roll off the leaf and small drops en -
hance the magnifying glass effect.
Due to the salt concentration in the fertiliser,
excessive application of fertiliser can cause
burning on the leaves.
3-jet nozzles (option)
The use of 3-jet nozzles for the application of
liquid fertiliser is beneficial if the liquid fertiliser
should mainly enter the plant through the roots,
rather than through the leaves.
The nozzle orifice integrated in the nozzle with
its opening ensures an almost pressureless,
coarse drop distribution of the liquid fertiliser.
This prevents the generation of undesired spray
mist and the formation of small droplets. The
coarse drops created by the 3-jet nozzle hit the
plants with low energy and roll off their surface.
