Underground system for treating soil
DCFirst Claim
1. A system for treating the soil and turf within a prescribed subsoil profile that includes:
- duct means positioned beneath the tuff, said duct means having openings therein that are in communication with the subsoil profile,connecting means for coupling the duct means to a supply line that is buried in the earth,blower means connected to said supply line for moving a flow of air to said duct means at a quantity and a pressure such that air passes upwardly through the subsoil profile andheat exchanger means that includes a length of air conduit buried beneath the ground and means of selectively directing said air through said buried conduit to change the temperature of said air.

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.

15. A system for treating the soil and turf of a region having a prescribed subsoil profile that includes
duct means positioned beneath the turf, said duct means having openings therein that are in communication with the subsoil profile, connecting means for coupling said duct means to a supply line buried in the earth, a blower means connected to said supply line by a four-way valve so that air can be selectively pushed upwardly through the sub soil or drawn downwardly through said sub soil.

21. A system for controlling the soil temperature of a grass playing field that includes:
-
a soil profile containing a lower gravel bed of a thickness of at least 4 inches, and a soil layer over the gravel bed for supporting turf, a duct network of interconnected perforated pipes buried in the gravel bed having perforations that are in air flow communication with the gravel bed, a blower means having a suction port and a discharge port that is connectable to said duct network, connector means for selectively coupling one of the blower ports to said duct network to either pass air upwardly through the entire thickness of the soil profile, or draw air downwardly through the entire soil profile to heat or cool the tuff, depending upon ambient air conditions. - View Dependent Claims (22, 23, 24)
