Hollow tining work being carried out on greens 2,3,4,12 to remove some organic matter from the turf surface. As these greens were lifted and re-laid last year we have not done as much aeration work to them over the past two years. A Humic acid product will be applied into the holes which will give some added nutrient to the sandy root zone. The core diameter was 16mm which has removed a lot of material from the surface.
