About Aeration of Lawns
Organic gardeners and horticultural professionals know that one of the secrets to having great lawns and gardens is having great soil. And that means a porous, well aerated soil where roots can grow deeply and where biolife can thrive. Compacted soils cause unhealthy plants, lawns and trees. They stay soggy when wet, and turn rock hard when they dry out in the summer. When soils are "tight", necessary air, water and nutrients cannot move through the soil. Disease occurs. Roots are stunted. Beneficial micro-organisms can't survive. Plants are stressed and weakened. When you are doing everything else right, soil compaction will ruin all your efforts.
