Liquid fertiliser operation
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
An 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 the corresponding
values for the application quantity (l/ha) from
the spraying table must be multiplied with 0.88
for AHL and 0.85 for NP-solution. The listed
application quantities (l/ha) apply only for water.
The following is generally valid:
Place liquid fertiliser in the form of coarse drops
to prevent burning of plants. Excessively 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 (optional)
The use of 3-jet nozzles for the application of
liquid fertiliser is beneficial if the liquid fertiliser
is to enter into the plant through the roots rather
than through the leaf.
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.
Even though damage caused by burning is
almost completely prevented, one should not
use 3-jet spray nozzles for late top dressing,
but use trailed hoses instead.
Only use the black bayonet nuts for all the fol-
lowing 3-jet nozzles.
Various 3-jet nozzles and their fields of
application (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)
NOTE
The pump must be flushed with fresh water af-
ter each liquid fertiliser operation. If not flushed
with fresh water, the pump seals may become
damaged!
