For the soil matrix in a well built green, pore space for gasses occupies approximately 25% of the total volume. A high concentration of oxygen in these pore spaces is needed for turf health (respiration) and active microbial decomposition of organics. Compaction, over-watering, layering and thatch buildup can reduce the amount of soil oxygen available to the plant. Poor gas diffusion will also cause the accumulation of toxic gasses such as carbon dioxide, hydrogen sulphide and methane. In addition to maintaining proper cultural and irrigation practices, forcing fresh air through the soil profile by means of subsurface aeration is a valuable tool for maintaining optimum soil conditions.

A subsurface aeration system utilizes the drainage network installed below the soil profile. The network, sealed from the atmosphere by special valves and connected to a high pressure blower unit is able, in vacuum mode, to pull air down through the profile and aid dewatering as well as aeration. The unit is also able, in pressure mode, to push fresh air up through the profile to aerate and possibly lower root zone temperatures to reduce stress.
