There are several benefits of liquid over mechanical aerations. While both forms of aeration offer multiple benefits to your lawn, liquid lawn aerations have some other things to consider. Liquid solutions are not just creating holes (or plugs) but introducing vital nutrients into your soil, breaking down thatch, and creating a food source to stimulate essential microbes. Soil activity created by these microbes will result in micro-tunnels throughout your lawn, necessary for water and nutrients to reach the plant's roots and drain when needed. Plus, no unsightly dirt nuggets are left behind to hang out on your lawn.
