Aeration

The introduction of air spaces into soil or growing media, essential for root respiration, beneficial microbial activity, and water infiltration. Compacted soil lacks adequate air spaces, leading to poor drainage, reduced root growth, and anaerobic conditions. Aeration can be achieved by mechanical means (core aeration of lawns, broadfork for beds), amendment (adding perlite, sand, or organic matter), or biological activity (earthworms, root channels).
