Abstract

The invention is a system and method for managing a plurality of areas of interest of a golf course. The system comprises a plurality of subsurface aeration subsystems and a programmable master control module. Each subsystem provides to a specific area at least one of air under pressure and a partial vacuum. In each area of interest, a local control module is responsive to a directive and to a datum (environmental or operational parameter). The local control module is configured to operate the subsystem and is in communication with the programmable master control module. The programmable master control module receives from the local control modules area information representing a status of the respective specific area to which the local control module is dedicated, and in response to the area information and to a command, the programmable master control module issues a directive to the local control module to operate the subsurface aeration subsystem.
