Which practice helps prevent soil structure decline due to compaction?

• A. Aeration and organic matter inputs
• B. Applying extra fertilizer only
• C. Increasing mowing height only
• D. Watering with cold water only

Answer: (A)

Preventing soil structure decline from compaction hinges on keeping the soil loose enough for air, water, and roots to move and grow. Aeration creates physical channels in the soil, relieving pressure and reducing density where roots would struggle. Adding organic matter inputs feeds soil life and helps form stable, crumbly aggregates that bind particles together while increasing pore space. This combination directly supports a resilient soil structure that resists compaction over time.

Fertilizer alone boosts nutrients but doesn’t change the soil’s physical density or porosity. Increasing mowing height alone doesn’t affect the soil’s structure, and watering with cold water alone doesn’t improve the soil’s ability to hold or move air and water.
