In order to avoid damages and ensure the safety of the operators the following rules should be followed. In case of doubt, feel free to consult with Gat fertilizers’ personnel.
Before applying the fertilizer, the grower should check the proper operation of the application equipment, and insure that the fertilizer’s characteristics are compatible with that of the equipment in order to avoid corrosion.
Check all the connections of the injection assembly, starting at the fertilizer container, and all the components up to the injection point, including all nozzles and accessories. Repair any leaks and replace worn tubing in order to avoid spilling fertilizer and polluting the environment.
A filter must be attached at the outlet from the tank or container. This filter should be checked and cleaned before each fertigation.
A check-valve must be installed up-stream from the injection point, and its performance must be checked frequently.
Irrigation should always continue some time after the required volume of fertilizer solution has been injected – as to flush- out any remaining fertilizer from the irrigation system.
When spraying or injecting a fertilizer solution – the sprayer’s tank, pump and nozzles must be flushed and cleaned with clean water whenever work is interrupted for more than one hour and always at the end of the day’s work.
