Parallel fertilization uniform distribution
It works in units of time or volume and has an indepen-
dent pre/post irrigation for each program.
For each fertilizer, there may be a mixer that stirs the
fertilizer tanks before and during irrigation.
The outputs where the fertilization elements can be
connected are assigned in ‘Function - 4. Parameters - 3.
Generals’.
FERTILIZATION PARAMETERS
No. fertilizers: 4
General fertilizer: yes
F1 mixer: no
F2 mixer: yes
F3 mixer: yes
F4 mixer: no
Pre-mixing: 015”
Mixing start: 030”
Mixing stop: 120 ”
End cleaning: 030”
F1 Meter: 01
F2 Meter: 02
F3 Meter: 03
F4 Meter: 04
Flow rate F1: 000.00 m3/h
Flow rate F2: 000.00 m3/h
Flow rate F3: 000.00 m3/h
Flow rate F4: 000.00 m3/h
Number of fertilizers (0 ... 4): enter in the unit the
number of fertilizers installed in the irrigation network.
Leave the value at 0 if there are none.
Fertilizer general (yes | no): is an output normally used
to connect the injector in series application and is only
activated when one of the fertilizers activates.
Enter yes if it is going to be used.
Fertilizer mixer (yes | no): each fertilizer can be assigned
a separate mixer. Indicate which fertilizers have a mixer.
Pre-mixing (000 ... 999”): time that the fertilizer will be
stirred before starting fertilization. Pre-mixing comes
in before the program starts. If it is less than 10 minutes
since the last irrigation, do not start the pre-mixing.
Mixing during fertilization can be continuous or with
pauses.
Mixing start(000 ... 999”): mixing time before a pause. If
continuous mixing is desired, set the mixing pause to 0
and any time here.
Mixing stop (000 ... 999”): time that the mixing will be
stopped aer a startning time. If continuous mixing is
desired, set this time to 0.
Final cleaning (000 ... 999”): when fertilization ends, the
general and fertilizer cleaning outputs are activated
during this time. If the fertilization is in series, it cleans
at the termination of each fertilizer. If it is in parallel,
when the last one ends.
Fertilizer meters
If fertilizer by volume, the meters must be assigned.
When fertilizer is parallel or uniform, a meter must be
assigned to each fertilizer; if it is series, the same meter
can be assigned to all fertilizers.
Meter F1, F2, F3, F4 (0 ... 10): meter sensor number asso-
ciated with the fertilizer.
Flow rate F1, F2, F3, F4 (000.00 ... 655.35): maximum
planned injection flow rate for these fertilizers. The
planned flow rate is used for uniform fertilization.
Uniform fertilization
With uniform fertilization, the fertilizer is distributed,
injecting small doses, throughout the irrigation. This
achieves better nutrient absorption, more homoge-
neous growth, drainage losses and sedimentation in
pipes.
It is applied using simple Venturi-type hydraulic
systems, reducing installation costs and can be done
in time and volume.
