1. Every time when the regulating valve on both sides of the fertilization valve of the quality Veturi Fertilizer is opened, the fertilization valve of Victorinox fertilizer should be opened slowly.

2. After each fertilizer application, close the two regulating control valves of the Veturi Fertilizer, take out the tank and rinse it, and take out the residual fertilizer in the tank to avoid losses.

3. After installing all the fertilization devices of the quality Veturi Fertilizer, install a first-level mesh filter to prevent unmelted fertilizer from being brought into the system of the Veturi Fertilizer and blocking the irrigator. If the Vickers fertilizer is installed, a filter should be installed before the Fertilizer is installed to avoid clogging the applicator.

4. After fertilizing with the quality Veturi Fertilizer, continue to flush the pipeline with clean water to avoid the fertilizer remaining in the irrigation system and causing blockage. The amount and depth of the quality Veturi Fertilizer can be adjusted according to the different needs of crops.
