Abstract
A system for treating the soil and turf having a prescribed subsoil profile that includes a duct network located in the subsoil region having openings that are in communication with the subsoil profile. A supply line is arranged to connect the duct network with a blower that provides low pressure, high volume air to the duct network so that the air is pushed upwardly through the subsoil profile to provide either heating or cooling to the soil and turf. A ground surface heat exchanger is positioned between the blower and the supply line for transferring energy between the earth and the air moving into the duct network. Other materials for treating the soil may be added to the air flow by a pressurized system. The blower flow is reversible whereby excess moisture can be removed from the green.
