2021年1月11日 · In the simplest soil profile, a soil has three horizons. In this diagram, a cross-section of soil shows different soil layers. The first horizon is the “A“ horizon. It is more commonly called the topsoil. The topsoil is usually the darkest layer of the soil. It is the layer with the most organic material.
A soil profile is a vertical cross section of the soil. When exposed, various soil horizons, or layers of soil, become apparent. Each horizon of soil may be different from the other hori-zons in physical or chemical ways. The differences are developed from the interaction of such
