Aeration is done twice per year as the most efficient way to reduce thatch build up in the turf's profile. Through years of study and science, the removal of cores using an aeration process is the best way to reintroduce beneficial air into the root zone while removing the build up of gases and anaerobic material. As a farmer can plow their fields to maximize crop production, we don't have the option to plow our greens/fairways. So as you see in these pictures, cores are taken and different types of sand (1 mm- 3 mm) is reintroduced to minimize interruption in play.

A golf course takes an incredible beating throughout any given year. Another cultural practice done during aeration is overseeding fairways and rough, usually at 6-8 lbs per 1000 sq ft. This ultimately produces a stronger stand of turf that is more drought tolerant, ware resistant and receptive to irrigation. 

After cores have been harvested and used for other purposes, sanding is done to help firm up any given area and re-introduce new clean sand that will better suit the profile and maximize growing conditions, leading to optimum playing surfaces.
