Listen, before anyone yells at me, aeration is an important necessity for greens. Aeration helps air and water get deeper into the dirt. It also prevents the soil from getting too compact, all of which is good for the grass’ root system. It’s really, really important.
Specifically, the proposal calls for a “minimum slope indication limit” that would allow green-reading books to continue to use numbers, lines, arrows or other indications to identify slopes on greens, but only in areas of 4 percent slope (2.29 degrees) or greater.
