End of Season Aeration

Once again we have arrived at the time of year when our most intensive period of aeration takes place.

Aeration is one of the most important maintenance tasks carried out on turf. The word aeration means quite simply to get air into something. In turf it is simply the production of holes through the turf surface into the underlying rootzone (soil) to allow gases (oxygen etc.) in and out of the soil and for water and grass roots to move down through the soil.

Starting this week we will be running two verti-drain type machines over all areas of the course. Fairways and high wear walkways will be tackled first. For these areas we use twelve 18mm x 300mm solid tines on each machine(see pic above). This allows us to make lots of holes in the turf and at sufficient depth to enable the movement of water more quickly through the soil beneath. The action of these particular machines also allows a certain amount of "heave" to be put on the soil. This lifts the level of the ground slightly allowing air and moisture to penetrate and relieve compacted areas. Compaction in the turf is caused by the regular movement of people or machinery over an area, wet soils compact more easily as the water in the soil acts as a lubricant allowing the particles to slide closer together and form a bond.

Next week we will start on greens and green surrounds. For these areas we will use a tine which is smaller in diameter but of a similar length. This smaller tine, coupled with some lightweight rolling will allow quicker recovery of the turf in these key areas. We hope to repeat this process in greens and surrounds in February 2010 and in future every October and February.
