Morning Dew

Why is it wet this morning?
Did you water last night?
Did it rain last night?
These are common questions that I receive from several golfing members.
In fact, we irrigate the turf as little as possible.
We irrigate only when the turf needs it to prevent wilt and turf loss.
Another reason for our limited irrigation is due to the poor quality of the effluent water that we use for watering the course.  It has a few elements that, in elevated amounts, have a negative effect on turf quality (sodium and bicarbonates.)

There is a term in the golf business "dew sweepers"
These are the early morning players who play before the morning dew has dried from the turf's surface. 

Below are a few photos of early morning golf course dew.
