ABSTRACT:
A device for preparing a deep fertilization hole in soil and for then facilitating dispensing a quantity of fertilizer into the hole formed after the device is used to remove a column of soil in forming the hole. The device includes a hole-making tube, an anvil tube, and a soil ejection rod, all coaxial one to another. The anvil is releasably connectable to the upper end of the hole-making tube. The anvil transmits hammering forces applied against its upper end to drive the lower end of the hole-making tube into the soil. The soil ejection rod is slidably translatable longitudinally within the hole-making tube and is provided to push the column of soil from the hole-making tube which has been removed in forming the fertilizer hole. Removal of the anvil facilitates use of the hole-making tube to deposit the fertilizer into the hole. The soil ejection rod having a scalloped, tooth-like soil ejection plate may be used to loosen the soil at the walls of the fertilization hole prior to reinsertion of the hole making tube for purposes of improved fertilizer absorption within the hole.
