Which practice contributes to healthy soil and turf structure?

Aeration contributes to healthy soil and turf structure by reducing soil compaction and allowing water, air, and nutrients to penetrate more effectively into the root zone. This process involves creating small holes in the soil, which helps improve root growth and encourages a healthier, more resilient turf. Aeration can also facilitate the breakdown of thatch, a layer of dead grass and roots that can inhibit water and nutrient absorption when it becomes overly thick.

The other practices mentioned do not have the same level of impact on soil and turf health. While hand pulling weeds can be beneficial in reducing competition for resources, it does not affect soil compaction or pore space significantly. Increasing fertilizer use can lead to nutrient imbalances or runoff issues, potentially harming the environment rather than fostering soil health. Mowing grass to an inch may not provide the optimal height needed for most grass types, potentially stressing the plants instead of promoting their health. Therefore, aeration stands out as the most beneficial practice for enhancing soil and turf structure.
