What is core aeration and why is it done?
Core aeration (also know as aerification, aerating, aerifying) is a maintenance practice that promotes healthy turf growth, especially in compacted surfaces such as putting greens. A machine, known as an aerifier, removes 3 inches to 5 inches long and 1/2-inch to 1-inch diamater cores of turf and soil. Usually done on an annual basis in conjunction with overseeding activities, aeration is the means to promote growth in compacted soils (due to heavy traffic or bad soil composition). The removal of cores allows water, air and nutrients to reach the soil roots, thereby enhancing growth.
