Which practice contributes to the reduction of soil compaction?

Proper aeration contributes significantly to the reduction of soil compaction. This practice involves creating small holes in the soil to relieve compacted areas, allowing air, water, and nutrients to penetrate more effectively. Aeration improves root growth and promotes better overall health for the plants in the area, leading to a more vibrant and resilient lawn or ornamental garden.

On the other hand, increased traffic on lawns can exacerbate soil compaction, as heavy foot or vehicle traffic compresses the soil particles closer together. Frequent watering may temporarily soften the soil but does not directly address the underlying issue of compaction and, if overdone, can lead to additional problems such as waterlogging. Heavy mulch application can provide benefits such as moisture retention and weed control but does not alleviate compaction in the soil structure. Thus, while good practices for maintaining healthy lawns exist, proper aeration is specifically effective in combating soil compaction.
