Soil forming processes

Reading the profile as a whole

Soil-forming processes rarely occur in isolation. Most soils are shaped by several processes acting together over long periods. The distinct layers we observe – called soil horizons – are the visible outcome of these interacting processes.

When you stand in front of a soil profile or a soil monolith, you are not just looking at layers of earth. You are looking at a record of movement, transformation, accumulation, and loss. A soil profile is not random. It is structured. It is dynamic. And it is readable.

The next time you see a soil profile, try to approach it like a detective. Start with the visible clues. Follow the evidence. And ask: What happened here? What shaped this place? And what does this soil reveal about the environment above it?
