The present invention discloses a hydroponic field irrigation system comprising a field module for growing turfgrass. The field module comprises an energy absorbing mechanism comprising a horizontal spring layer and a growth medium comprising a steel grid layer, wherein the horizontal spring layer absorbs vertical forces exerted by external loads, and the steel grid layer is positioned on top of the horizontal spring layer for holding a plurality of turf sods. The hydroponic field irrigation system further comprises a used water tank for receiving water from the field module, an ultra-violet (UV) unit for disinfecting the water received from the used water tank, a water quality management unit for adjusting quality of the water received from the ultra-violet (UV) unit, a geothermal unit for conditioning temperature of water received from the water quality management unit and plurality of solenoid valves for pumping water into and out of the field module.

There is provided a hybrid turf support for use with natural grass to form a stable hybrid turf system, the hybrid turf support comprising a knitted reticulated support; and a plurality of grass-like fibers extending upwardly from the knitted reticulated support, the grass-like fibers comprising groups of fibers extending upwardly at intervals.

A turf management system includes a wireless receiver that is configured to receive respective wireless signals comprising sensor data from wireless sensors positioned in a soil profile at respective depths below a green surface. A control circuit is coupled to the wireless receiver and is configured to determine soil profile conditions at the respective depths below the green surface responsive to the sensor data. The control circuit is coupled to a subsoil environmental control mechanism and is configured to automatically control operation of the subsoil environmental control mechanism responsive to the soil profile conditions at the respective depths below the green surface. The subsoil environmental control mechanism may include a hydronic mechanism that is configured to circulate fluid through a hydronic tubing network below the green surface.

A hybrid grass support structure (100, 200, 300, 400, 500, 600, 710) comprising a growth medium layer (102), a stone wool layer (104) positioned below the growth medium layer, and a plurality of synthetic grass fibers (106). The growth medium layer comprises a growth medium. The synthetic grass fibers are incorporated at least into the growth medium layer.

A turf sports field with a plurality of turf modules (100) having an upper turf surface and peripheral turf edges (5). The turf modules are deployed by means of a remotely operated or autonomously operated lifting and transport vehicle (103), which is provided with a lifting arrangement. When installed, the turf modules (100) are positioned adjacent previously installed turf modules, with a tolerance gap (105) between adjacently positioned turf edges (5) of different turf modules.
