Thatch Dilution

During the first part of March we did a few solid tine cultural practices to the greens. We first topdressed greens with sand to  1/2 ton per 1000ft2. Second we solid greens with a 1/2 inch solid tine to the depth of 1.5 inches. This is to create a fill area for the sand to end up in the area in which we know there is more organic accumulation. Then we had a 1/2 inch deep tine performed to the depth of 7 inches at a 8 inch spacing to loosen the soil to a deeper depth. This will encourage deeper root growth. 
No aeration plugs were  removed during this process. 
Brushing, blowing and handwatering in the sand was followed for the finial steps. With the new irrigation system not completely in operations at this point we were able to get water to all greens surrounds for handwatering options. This was a huge help.

Holes filled with sand 

Top 1-1 1/2 inch is where the majority of the slow water infiltration is and organic matter is the problem
