Abstract: A container for solid water soluble fertilizer pellets supported in an upright position by a short vertical water supply pipe through an upper integral inlet pipe and a lower integral outlet pipe. The inlet pipe has a formation designed to direct a portion of a downward stream of water in the supply pipe into the container to augment the force of gravity and cause the diverted water to flow over pellets in the container. The outlet pipe is located at the lower end of the container to direct the water, now with dissolved fertilizer in it, back into the supply stream. A formation on the outlet pipe coacts with the supply stream to aid in circulating water through the container and over the pellets.
