What practice can alleviate soil compaction in turfgrass areas?

Aeration practices are highly effective in alleviating soil compaction in turfgrass areas. This method involves perforating the soil with holes to allow air, water, and nutrients to penetrate deeper into the root zone. Compacted soil restricts these essential elements from reaching grassroots, leading to poor growth and increased susceptibility to pests and diseases. By aerating the turf, you create channels that improve root development and overall lawn health.

In contrast, while fertilizing regularly can enhance turf vigor, it does not address the physical issues of compaction. Watering deeply is beneficial for maintaining moisture but does not physically relieve compaction. Using organic mulch can be useful in other contexts, such as in landscaping or garden beds, but it does not directly remedy compacted soil in turfgrass areas. Thus, aeration stands out as the primary practice to effectively reduce soil compaction, promoting a healthier and more resilient turf.
