2.4.1
Global Accumulative fertilizers limit
There is an option to define global seasonal limits per each fertilizer type of each
valve so that the system will protect us from fertilizing more than necessary. During
each fertigation process, the quantity left to reaching the limit gets smaller and
smaller and when becoming zero the injection of the particular fertilizer will not
continue. The option of using the
GLOBAL FERTILIZERS LIMIT
must be enabled
through the
DEALERS DEFINITION
.
2.4.2
Sequential fertilization
As a default, when there are several fertilizer injectors at the fertilizer site, they will
work in parallel, however when it is important not to let the fertilizers mix inside the
irrigation line, there is an option to request the injection to be serial instead of
parallel. In order to use this option it must be enabled at the
DEALERS
DEFINITION
.
In the sequential injection mode the fertilizers will be injected one after the other
with some flushing of the fertilizer line taking place between the injections. For the
purpose of flushing the last fertilizer injector will be used. The amount of fertilizer
defined to be injected by the last injector will actually define the amount of water (or
other liquid) to be used for cleaning the pipe.
In order to make sure that the fertilizer pipe is clean at the beginning of the injection
process, we start by activating the last injector and flush the line, but this time it will
inject only half of the amount defined for flushing.
Notice that:
In the sequential fertilization mode the dosing of fertilizers can be by volume
or by time but Bulk only, no proportional fertilization is permitted.
When the sequential fertilization mode is selected at the
DEALERS
DEFINITION
the selection holds for all the fertilizer sites of the controller.
