Abstract

A fertilizer applicator for solid fertilizer is provided, and is inserted into a sprinkler line system. The applicator comprises a container component which encloses and suspends a fertilizer holder component and spaces the two conponents to define a water pressurization chamber therebetween. Water is fed from the container through the pressurization chamber and into the bottom of the fertilizer container where it dissolves some of the fertilizer and forms a leached, concentrated solution. This leached solution rises through the fertilizer and into overflow tubes where it drains downwardly through the bottom of the fertilizer holder. The concentrated solution is then diluted with water draining from the bottom of the water pressurization chamber, and the diluted solution of fertilizer is passed into the sprinkler system for application to vegetation. The applicator has no moving parts, and has a simplified design. The applicator reduces problems due to plugged drain bores, and channeling effects through the solid fertilizer.
