FARMERS have been warned
about the dangers of nitrate poi-
soning after three cows died in
Dr Grant Nielsen from West
Gippsland Vet Care said current condi-
tions were conducive to nitrate poison-
ing, with farmers needing to be aware
of what causes the illness and how to
identify symptoms of sick animals.
“You tend to see nitrate poisoning
in cattle if they are hungry and going
onto new pasture or capeweed that has
been sprayed, which increases its pal-
atability,” Dr Nielsen said.
“Farmers need to try and control
the intake of new pastures or sprayed
“They can strip graze to minimise
the impact or get the grass and cape-
weed tested to see how high the nitrate
With overcast conditions being
a precursor to nitrate poisoning, Dr
Nielsen said farmers should try to take
the weather into account when plan-
ning grazing regimes.
“Try to avoid grazing in overcast
conditions, which can be tricky,” he
“But try to make sure cattle are well
fed, having concentrates in the diet so
there is plenty of energy in the rumen,
which is important.”
Dr Nielsen said animals that are
urinating frequently and staggering
may be suffering from nitrate poison-
ing and need immediate veterinary as-
“You can have sudden death within
an hour of grazing, depending on how
toxic it is,” he said.
According to the Dairy Australia
website, nitrate is a normal component
of plants and is usually converted in
the rumen to nitrite which is, in turn,
changed to ammonia.
If nitrate levels in plants are higher
than usual and/or the conversion of ni-
trite in the rumen is too slow, nitrate
concentrations in the rumen can build
up to toxic levels.
Excess nitrate is absorbed into the
bloodstream where it binds with hae-
moglobin and reduces the ability of the
blood to carry oxygen.
Nitrate can build up in many plants
including pasture species such as rye
grass, fodder crops such as millet or
brassica, or weeds such as capeweed.

Nitrate poisoning alert
NEW Amazone ZA-V linkage-mounted
spreaders deliver all of the precision and
innovation found in the professional ZA-
TS series but in a more ‘everyday’ size.
Available in a range of hopper sizes from 1700
litres to 4200 L, they feature automatic calibra-
tion, on-board weigh cell and tilt sensor technol-
ogy and many other innovations not typically
found in medium-sized spreaders.
All models feature Amazone’s proven ‘soft
ballistic pro’ technology, which ensures all com-
ponents of the agitation, metering and spreading
system are optimally matched to protect the integ-
rity of fertiliser granules.
Claas Harvest Centre South Gippsland’s An-
thony Blackshaw says the ZA-V builds on more
than 50 years of leadership in twin-disc centrifu-
gal spreading technology.
“Amazone is the undisputed world leader in
spreading technology,” he said.
“The ZA-V is a completely new series based
on Amazone’s tried and proven ZA technology
used in one million spreaders since 1958.”
With a maximum discharge rate of 6.4 kg/
second, a working width of 36 m and operational
speeds of up to 30 km/h, the ZA-V delivers top-
end spreading performance.
Three sets of quick-change discs achieve a per-
fect ‘three dimensional’ spreading pattern from 10

An optional tilt sensor monitors and adjusts
the spreading pattern in undulating conditions.
“Optional low level sensors in the left and
right hoppers send a warning message to the ter-
minal once pre-set minimum fill levels have been
reached,” Mr Blackshaw said.
“Spreading with one side at a reduced spread
rate or one-side only can result in the uneven
emptying of the hopper.”
Profis models are equipped with an Isobus job
computer as standard.

Mr Blackshaw said.
“Alternatively, there is the option of the new
Amaspread+ operating terminal, which was de-
veloped specifically for fertiliser application.”
The 145 mm display features illuminated keys,
large icons and easy menu navigation.
The settings for up to 20 different fertilisers
can be stored and recalled at any time.
In addition, it stores all of the details for up to
99 jobs, including area, fertiliser type, application
rates, quantity applied and the time taken.
Amaspread+ also controls the new Limiter
V+ border spreading deflectors, which improve
spreading accuracy along borders and water
courses without leaving the cab.
All Amazone controllers can be equipped with

guidance and GPS-Maps variable rate technol-

trol, which features a speed-related metering sys-
tem, and the ZA-V Easy, which features a simple
electric on/off control.
