The layer that contains the most humus and smaller rocks is the topsoil layer. Topsoil is the uppermost layer of soil that is rich in organic matter, such as humus, and contains smaller rock particles that have undergone weathering. It is the most fertile layer of soil and is crucial for plant growth.
The top layer of soil, called the O horizon or organic layer, contains humus. Humus is a dark, organic material that forms as plant and animal matter decomposes. It is rich in nutrients and helps improve soil structure and fertility.
The topsoil layer and the organic matter layer are likely to contain humus. Humus is a dark, organic material that forms from the decomposition of plant and animal matter, enriching the soil with nutrients and improving its structure and fertility.
The top layer of soil, known as the O horizon or organic layer, is the most newly formed. It consists of organic material such as leaf litter and is constantly being replenished by decaying plant matter.
The process you are referring to is called organic matter decomposition, which results in the formation of a layer of soil called humus. Humus is a dark, nutrient-rich material that improves soil structure and fertility.

Soil is made up of a thin layer of weathered rock, humus, air, and water.
The layer of soil that has little or no humus in it is the subsoil. The top layer of the soil has the most humus in it because the dead leaves fall from the plant and go back into the soil. Water and sun also help give the plant humus.
