Aerification system

An aerification system for controlling a moisture content and gas exchange below a surface portion of one or more areas to be irrigated, said system comprising:

• at least a first and a second aerification sub-systems being in fluidic communication with said one or more areas, and being installable in a recess above which said surface portion is located;
• at least one conduit arranged to fluidically connect said first sub-system to said second sub-system;
• and
• at least one pumping system for pumping a fluid back and forth between said first sub-system and said second sub-system;
• wherein said fluid from said first sub-system is at least partly transferable by said pumping system via said at least one conduit to said second sub-system and wherein said fluid from said second sub-system is at least partly transferable by said pumping system via said at least one conduit to said first sub-system and wherein said pumping system is further configured to periodically raise and lower a height level of said fluid between a predetermined minimum height level value and a predetermined maximum height level value in the first and second sub-systems enabling a gas exchange below said surface portion.
