ABSTRACT:
A hand-held apparatus is connected by means of an air hose to a high pressure compressor and air tank unit, and is connected by means of a hose to a conventional water faucet. The device includes a bin for storing granular fertilizer and an air valve connecting the high pressure air supply into a rigid outer tube that is inserted into a pre-drilled hole in the ground. An operator stands on a horizontal ground plate attached to the outer tube to seal the hole, and opens that air valve to force high pressure air into the predrilled hole, creating many small crevices in the soil around the roots of a plant. The fertilzier in the bin then is released into the outer tube. The high pressure air valve is reopened. The high pressure air forces the granular fertilizer out of the bottom of the outer tube and into the previously created crevices. Pressurized water then is conducted through a water valve to an inner tube concentric with the outer tube, forcing the water into the crevices, dissolving the fertilizer, moisturizing the soil and roots, and sealing the crevices by causing the moistened soil to collapse.
