Methods and systems for applying a uniform layer of a substance such as a hydrogel or other fluid substance beneath a soil surface with minimal or little surface disturbance to the plants, the plant roots and the soil located on or slightly below the applied surface area. Embodiments include injecting a fluid substance into soil using at least one injector probe, a driver to drive the at least one injector probe into and out of the soil to and from a target depth, and a rotator mechanism configured to rotate the at least one injector probe about a central axis from one angular position to another angular position at the target depth.

In a system (10) for managing a soil treatment business, an injection apparatus (12) is operable to inject soil treatment under high pressure down into soil. A control system (92) is associated with the injection apparatus (12) and is configured to collect data during operation of the injection apparatus (12). A data management system (801) is configured to receive the data collected by the injection apparatus (12) control system (92). The data management system (801) generally comprises a database for storing the collected data, with the data management system being accessible by the business for reviewing the collected data.

In a method for treating soil at a work site, a first pressure application tool is connected to a base unit and moved relative thereto along a first area of the work site adjacent a structure and operated to inject soil treatment down into the soil along the first area of the work site. A second pressure application tool is interchanged with the first pressure application tool and moved relative to the base unit along a second area of the work site adjacent the structure and different from the first area of the work site. The second pressure application tool is operated to apply soil treatment to the soil along the second area of the work site.

A ground treatment apparatus comprises a support device, injection elements, a fluid providing device that is fluidically connected to the injection elements, a drive device by which the injection elements are on the one hand lowerable and raisable in relation to the support device and on the other movable along a working direction of the ground treatment apparatus. The injection elements are insertable into the ground by being lowered in order to inject fluid into the ground in a treatment region, wherein the injection elements remain stationary during engagement in the ground in the treatment region, with relative movement in relation to the support device that is moved in the working direction, wherein the injection elements are raisable after the injection of fluid and are movable in the working direction in relation to the support device, wherein, on being lowered again, the injection elements are insertable into the ground in a further treatment region that is downstream of the first-mentioned treatment region, as seen in the working direction.

An aerator device. The aerator device includes a manifold including an interior channel, a connector aperture, and a plurality of nozzles configured to discharge a pressurized fluid stream. A cover plate is disposed on an upper side of the manifold. A first connector includes a first open end in fluid communication with the interior channel and a second end extending through a connector aperture disposed on an upper side of the cover plate. A second connector is configured to receive a hose connection to a pressurized fluid supply. A wheel including a wheel height adjustment mechanism is affixed to each side portion of the cover plate. In one embodiment, the manifold is configured to rotate when the wheels of the device rotate via a drive roller. A handle extending rearwardly from the cover plate includes a trigger mechanism configured to activate the flow of fluid from a pressurized fluid source.

In a method and apparatus (710) for treating soil at a work site, a high pressure application tool (712) is connected to a base unit (714) and moved relative thereto along a first area of the work site adjacent a structure (94) and operated to inject soil treatment down into the soil along the first area of the work site.
