Scarification

The penetration of the turf surface into the underlying organic or soil layer by the use of a scarifying implement. It is carried out to help control thatch, remove moss and to raise up flattened vegetation or lateral growing stems. It can be thought of as a scoring or marking of the surface. A light to medium scarification of a sward should not cause any disruption to play, although a severe or deep scarification will most likely result in some disruption.
