Following on from the maintenance work carried out in September, which included verti-draining and solid tining, further aeration in the form of micro hollow coring is being carried out on the greens.
This form of aeration (hollow coring), removes 6mm diameter plugs to a depth of 100mm. The coring is carried out to relieve surface compaction caused by foot and maintenance traffic. Other benefits of coring include air exchange, improvement to surface drainage and increased root development. Another benefit is the removal of dead and decaying organic plant material, (thatch) found in the upper profile, which if left unmanaged could cause problems. Organic matter levels in the greens are now down at a healthy level of 5%. More information on this can be found in the current STRI report.
The nature of the small diameter tines causes minimal disruption with large benefits.
