You will need to calibrate your sprayer to ensure the accurate application of chemical or liquid fertilizer. If too much
chemical or liquid fertilizer is applied you will be wasting money! If too little is applied you may need to repeat the
spraying,
which
will
be
wasting
your
money
and
time!
Chemicals
are
expensive.
Repeat
calibration
frequently
during
the
seasons
to
avoid
disappointment.
To
calibrate
your
sprayer
you
will
need:
a) nozzle
calibrator
or
an
accurate
measuring
flask
b) watch
or
clock
with
seconds,
or
a
stopwatch
c) tape-measure
d) calculator
NOTE:
“Chemical
“
also
refers
to
liquid
fertilizers.
