Soil Profile Diagram - Layers, Composition & Root Penetration #1838130 (License: Personal Use)

The image depicts a cross-sectional view of soil structure, highlighting the O (organic), A (topsoil), B (subsoil), and C (parent material/bedrock) horizons. Dark brown organic-rich surface layer transitions into lighter mineral-rich subsoils, with roots visibly penetrating multiple layers. Subtle shading and layering emphasize texture, composition, and biological activity.
