Aeration to greens

All greens were aerated with 1/2 inch hollow tines to a depth of 2.5 inches at a 1 inch spacing. All plugs collected and removed from greens. 

Removing plugs to get ready for sand.

Brushing and blowing sand. Practicing social distancing with the corona virus happening across the country.
Sand was added at 1/2 ton/1000 ft2 and rain followed that night. A second application of sand will be added to the greens next week at 1/4 ton of sand per 1000ft2 

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

Irrigation renovation

The Irrigation renovation is under way! Close to 30 years of the original irrigation system and the time has come to replace it. The heads, fittings and pipe are past the expected life span. The new system is a state of the art Rain Bird IC system. There will be no control boxes on the course. Each irrigation head is basically its on computer module. We will have all controls through a central controller in the turf care facility along with I pads and app use through our cell phones.
The new system will give us better individual control of each head and allow for better water management throughout the entire course.
