ABSTRACT:
A method and apparatus for treating turf to reduce the general soil density in which turfgrasses grow and thus promote turf growth and turf drainage which includes injecting through the turf into the soil a pattern of jets of generally incompressible liquid at a jet pressure and jet spacing to provide a lateral dispersion of the liquid within the soil such that the liquid dispersion from adjacent jets coact with one another to lift and fracture the soil. A plurality of small diameter nozzles are mounted on a movable frame generally transverse to the direction of travel of the frame. A pressurized fluid source is mounted on the frame and connected through a control device to the nozzles. The control device control the flow of liquid from the pressure source to the nozzles to produce periodic, relatively small cross-sectional, slugs, or jets, of liquid from the nozzles through the turf into the soil. The pressure on each slug of liquid is such that the liquid penetrates through the turf into the soil and also disperses generally laterally within the soil. The spacing of the nozzles and the speed of travel of the frame are such the lateral dispersion of each slug of liquid coacts with adjacent slugs to lift and fracture the soil, thereby reducing the compaction, or general density, of the soil and promoting turf growth and drainage.
