ABSTRACT:
Plant fertilizer in granular form is supplied as replaceable cartridges and gradually dissolved within the cartridge shell by a side branch of the main stream of water which flows straight through the base of the feeder with minimum pressure loss. The cartridge container is a frustoconical disposable shell the base closure of which has a central orifice for metering inflowing water and peripheral fertilizer solution outlet holes. A port in the top of the main channel directs the side branch flow against the cartridge closure at the metering orifice to flow into the body of fertilizer and a second port receives solution from outlet apertures in the closure to rejoin the main stream at an enlarged portion of the main channel to provide suction. A dome screwed into sealed engagement on the top of the feeder encloses the cartridge.
A safety valve is provided at the top of the dome to permit trapped air to escape through a central aperture.
