WebDec 21, 2024 · Lawn aeration is the process of puncturing the soil with small holes that aid vital elements, such as air and water, to enter the grassroots. This process helps the roots to grow deeply, which in turn produces a stronger and livelier lawn. The main purpose of lawn aeration is to provide air and breathability to your lawn and the soil underneath it. WebSelf-aeration is an interfacial aeration process, with an uncontrolled supply of air. Next to the free-surface, the entrained air is advected in region of low shear (10).
