The apparatus of the invention is configured to deposit a fluid, such as a hydrophilic polymer solution, into existing sod. The apparatus includes a frame, a cylindrical housing, spikes protruding perpendicularly away from the housing, two rotating hubs, a tank, tubing connecting the tank to the rotating hubs, tubing connecting the rotating hubs to the spikes, and a pump for pumping fluid from the tank to the rotating hubs where the fluid is forced into the spikes and ultimately into the earth. The apparatus is also configured such that the fluid is only expelled from the spikes while the spikes are in the earth.
