The base can be secured to ground or other support frames using 4 nails or screw bolts passing through the installation holes.
In some embodiments, the water outlet connection pipe (227) is disposed on the top side (215) of the base with water flow direction perpendicular to the top side (215), wherein the water outlet connection pipe (227) is lower than the side walls of the bar holder (230) but higher than the bar support pipe (240). The water outlet connection pipe (227) is such configured that incoming water has to submerge a part of the fertilizer bar before the water can flow out from the water outlet connection pipe.
In some embodiments, the device further comprises a water inlet valve (260) disposed within the water inlet pipe (216), wherein the water inlet valve can move between an open position and a closed position for respectively allowing and preventing the inlet flow of water. The water inlet valve can be controlled electronically or manually. In some embodiments, the water inlet valve (260) is controlled manually by a water inlet valve control knob (270) on the water inlet pipe (216).
In some embodiments, the base is made of plastics, such as ABS, polypropylene, high density polyethylene (HDPE), etc.
