Question

In which soil layer would you find loam that is rich in humus?
C horizon
A horizon

Answer 1

You would find loam that is rich in humus in the **A horizon**. The A horizon, often referred to as the topsoil, is where organic matter, such as decomposed plants and animals (humus), contributes to soil fertility and structure. The C horizon, on the other hand, consists primarily of weathered rock and mineral material and typically contains little to no organic matter.
