Liquid Fertilizer Maintenance
Agricultural Chemical Hazard
Some chemicals will cause serious burns, lung
damage, and death. Avoid contact with skin or
eyes. Avoid prolonged breathing of chemical
fumes. Wear respirator and other protective
equipment as required by chemical
manufacturer. Seek medical assistance
immediately if accident occurs. Know what to
do in case of an accident.
Chemical Hazard
Store and dispose of unused chemicals as
specified by the chemical manufacturer.
Review all instructions on the material
containers and material safety data sheets.
Proper attention to maintenance, end of the day
clean-out, and end of season clean-out and
winterizing, can substantially increase the life and
reliability of your fertilizer system.
Protect the pump, clean the tanks, strainers, lines,
and nozzles to avoid costly and time consuming
repairs at the next season.
Fertilizers are usually highly corrosive to metals other
than stainless steel. Suspension fertilizers can clog
system components in storage.
Refer to the pump manual for detailed maintenance.
Pump Damage Risk
Do not leave fertilizer or fertilizer residue in the
pump. Do not allow air to enter the pump. Even for
short periods of storage, air entering the pump
causes rapid and severe corrosion.
1. Flush the entire system with clean water. Do this
at the field last treated, or other location
compliant with the chemical supplier clean
- up
instructions.
2. Remove the strainer and drain it. Drain all lines
and tanks completely to prevent freezing
damage.
3. Flush the pump according to the pump operator
manual. Fill the pump with RV antifreeze and cap
off.
4. Wash all spilled fertilizer off the planter.
Tank Clean - Out
1. If the pump has already been filled with RV
antifreeze for storage, close the pump valve.
2. Move the planter to a location suitable for
draining the material. A site with access to rinse
water is best.
3. Open the quick-fill valve to allow leftover material
to drain.
4. Open the tank lids. Check for build - up,
sedimentation, and foreign matter, particularly
any large objects.
5. Clean one tank at a time.
6. Slowly open the tank valve handle.
7. Power
- wash the inside of the tank from above.
8. When the tank is clean and drained, close the
tank valve.
9. Close the tank lid.
Liquid Fertilizer Strainer
The fertilizer system uses an in-line strainer to keep
damaging particulates out of the pump. The strainer
can become clogged over time, reducing the pump
rate. Clean the strainer several times per season. Do
not wait until application rates fall below target.
Higher quality liquid fertilizers may require less
frequent cleaning.
Disassemble and clean the strainer before storage to
prevent caking.
In Season Filter Cleaning
1. Shut off the ball valve at the filter to minimize
product spill.
2. Unscrew and remove the bottom canister (1) of
the filter.
3. Wash the filter cartridge (2) with water or replace
with new cartridge if necessary.
4. Reinstall the cartridge, canister, and turn on the
ball valve.
End of Season Filter Cleaning
1. Load 10 to 15 gallons (40 to 60 liters) of clean
water in the tank.
