ABSTRACT:
In one embodiment of the invention a fertilizer spike insertion tool includes a hammer coupled to a spring. When loaded the hammer is retained by a detention member and the spring is loaded (e.g., compressed or expanded). On releasing the detention member and unloading the spring, the hammer forcibly impacts a footrest and drives a hollow metal core into soil making a hole for a fertilizer spike.
