What does scarifying involve in soil management?

Scarifying involves disturbing the soil surface to reduce compaction, which is essential in soil management for several reasons. When soil becomes compacted, its structure may hinder water infiltration, root growth, and nutrient absorption, which are critical for plant health. By scarifying, you are effectively loosening the top layer of the soil, allowing air, water, and nutrients to penetrate more easily. This process improves the overall soil structure, encourages microbial activity, and enhances the environment for vegetation to thrive.

The other options do not accurately describe the process of scarifying. Creating a smooth surface pertains more to leveling activities than addressing soil compaction. Planting deep roots is a separate practice focused on root development and does not directly involve altering the soil surface. Covering soil with mulch serves another purpose, primarily for moisture retention and weed control, rather than addressing compaction issues. Understanding these distinctions highlights the specific role of scarifying in effective soil management.
