A soil aerator fertilizer especially adapted for the treatment of trees in an orchard-like setting includes hydraulic cylinder units mounted on opposing sides of a trailer or vehicle so that trees on either side of the trailer can be simultaneously treated while the trailer is intermittently moved through the orchard. Each of the hydraulic cylinder units includes an extensible piston having a ground penetrating probe attached thereto. The trailer or vehicle also supports a source of hydraulic fluid, a source of pressurized air or gas, a source of an aqueous fertilizer and/or nutrient mixture, and valves for selectively controlling the flow of pressurized hydraulic fluid to and from the hydraulic cylinder units and for selectively supplying either pressurized air or gas, or liquid fertilizer and/or nutrient mixture to the probe for distribution below the surface of the soil. A four-position T-shaped control valve is used for selectively directing pressurized air or liquid fertilizer and/or nutrient media to each of the probes once they have been inserted beneath the surface of the soil. The subsurface aeration and application of aqueous treatment media in accordance with the present invention reduces or eliminates environmental contamination, reduces or eliminates fertilizer or other treatment chemical requirements, and increases plant, tree or crop production.

[ I claim:] [1.] A fertilizer injection system for sequentially driving at least one probe into the soil, injecting at least one of air and liquid products into the soil, and then removing the probe, comprising:at least one hydraulic ram having an elongate cylinder with respective hydraulic fluid ports for introducing and extracting hydraulic fluid, a piston at least partially received within said elongate cylinder with one end extending outwardly from said cylinder,an elongate fertilizer probe having a first end attached to said one end of said piston, a second end terminating in an insertion point with at least one discharge opening, and an elongate fluid passage extending from said first end of said probe to said discharge opening,at least one fertilizer port for receiving and delivering at least one of pressurized air and liquid products to said elongate passage at said first end of said probe, said fertilizer port being located in said one end of said piston adjacent said first end of said probe,a source of hydraulic fluid for selectively supplying hydraulic fluid to said hydraulic fluid ports of said cylinder,a source of pressurized air for selectively supplying pressurized air to valve means,a source of liquid products for supplying said liquid products to said valve means,said valve means for selectively directing at least one of pressurized air and liquid products, to said fertilizer port for discharge from said probe into the soil following insertion of said probe into the soil, andhydraulic control means for selectively controlling the extension of said piston and insertion of said probe into the soil and the retraction of said piston into said cylinder and withdrawal of said probe from the soil.
