AbstractA system and method for conditioning turf at of one or more golf course areas includes an aeration subsystem having subsurface aeration conduits for aerating the area, and an air blower unit in fluid communication with the aeration conduits configured to provide one of a vacuum in a vacuum mode and air under pressure in a pressure mode in the conduits. A control module is provided which responds to a directive for controlling operation of the aeration subsystem in response to sensing environmental parameters. The control module operates the blower in repetitive cycles of intermittent operation in one of the vacuum mode and pressure mode wherein each cycles includes a blower-on and blower-off mode. The blower-on mode operates the blower units for a first time interval and the blower-off mode ceases operation of the blower units for a second time interval during each cycle.
