A method of enhancing the soil structure of land having a topsoil layer and a subsoil layer beneath the topsoil layer includes providing at least one subsoil tiller blade having a tilling surface and a bottom end, and a channel positioned behind the tilling surface of the subsoil tiller blade for injecting nutrients toward the bottom end of the subsoil tiller blade. The subsoil tiller blade is inserted into the land such that the bottom end extends into the subsoil layer. The subsoil tiller blade is driven through the land such that the tilling surface loosens the subsoil layer while the channel deposits nutrients into the subsoil layer.

The apparatus of claim 1, comprising two or more subsoil tiller blades. 3. The apparatus of claim 1, wherein the conveyor is one of an auger, a belt, a pneumatic system, a pump and a dispenser. 4. The apparatus of claim 1, wherein the storage tank is a hopper and the nutrients are in the form of pellets. 5. An apparatus for use in enhancing the soil structure of land having a topsoil layer and a subsoil layer, the apparatus comprising: a support frame;two or more subsoil tiller blades mounted below the support frame, each subsoil tiller blade having a tilling surface that loosens the subsoil when driven through the land, and a bottom end, the at least one tilling surface being spaced from the support frame a distance that causes the tilling surface to extend to a depth of between 20 cm and 50 cm below a top surface of the topsoil layer and into the subsoil layer;a storage tank having a conveyor for conveying nutrients into an outlet of the storage tank;two or more channels, each channel mounted to a separate one of the two or more subsoil tiller blades, each channel having an inlet connected to the outlet of the storage tank and an outlet toward the bottom end of the at least one subsoil tiller blade for depositing the nutrients at a depth of between 20 cm and 50 cm below the top surface of the topsoil later and into the subsoil layer, and wherein the outlet of at least one channel is at a different depth than the outlet of one or more other channels.
