Fertilizer System Maintenance

With proper attention to maintenance, end of day clean-

out, end of season clean-out and winterization, you can

substantially increase the life and reliability of your liquid

fertilizer system. Protect the pump, clean the tanks,

strainers, lines and nozzles, and you can 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 sys-

tem components in storage.

1. Flush entire system with clean water.

2. Remove end caps from booms and ﬂush booms out

with water. Drain and replace end caps.

3. Remove strainer and drain it out. Drain all lines and

tanks completely to prevent freezing damage.

4. Flush pump per pump supplier manual. Fill pump

with RV antifreeze and cap off.

5. Wash all spilled fertilizer off the air drill.

Liquid Fertilizer Strainer

Refer to Figure 94

The fertilizer system uses an in-line strainer to keep

damaging particulates out of the pump. The strainer

becomes clogged over time, reducing pump rate. Plan to

clean the strainer several times per season. Don’t wait

for application rates to fall below target. Higher quality

liquid fertilizers may require less frequent cleaning.

Disassemble and clean the strainer prior to storage to

prevent caking.

In Season Filter Cleaning

1. Shut off the ball valve at the ﬁlter.

2. Unscrew and remove the bottom canister . It is

generally not necessary to remove the plug ,

although doing so may ease cleaning of the canister.

Make sure the plug is tight when re-installing.

3. Wash the ﬁlter cartridge with water, or replace

with new cartridge if necessary. Inspect the screen

and O-rings for damage. A new cartridge includes

(cartridge) O-rings

4. Inspect the large O-ring on the canister. Replace

as necessary.

5. Reinstall the cartridge, canister. Turn on ball valve.

End of Season Filter Cleaning

1. Load 10 to 15 gallons (40 to 60 liters) of clean water

in each supply tank.

2. Pump most of it through the system. If doing this by

hand-turning the ground drive wheel, ﬁrst install the

largest drop-line oriﬁce size, and set the pump

adjuster to maximum, to increase ﬂow.

3. With valves open, remove the canister. Clean

strainer and canister.

4. Drain tanks and lines. Remove boom end-caps to

drain wings.

5. Re-install strainer and canister.

6. Add 2 pints (1 liter) of RV antifreeze to each tank.

Pump until tank is just empty (which leaves some

ﬂuid in strainer).

7. Open supply line above pump inlet. Introduce RV

antifreeze, and operate pump until pump is ﬁlled.

Possible Chemical Hazard:

Wear proper protective equipment as required by chemical

supplier. Avoid prolonged breathing of chemical fumes. Wear

respirator as required by chemical manufacturer. Some chemi-

cals will cause serious burns, lung damage, and death. Avoid

contact with skin or eyes. Seek medical assistance immediately

if accident occurs. Know what to do in case of an accident.

Equipment Damage Risk:

Do not leave fertilizer or fertilizer residue in pump. Do not

allow air to enter pump. Even for short periods, air in pump

causes RAPID and SEVERE CORROSION.
