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 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.
Soil that contains humus is known as humus soil. Humus is a dark, organic material that forms when plant and animal matter decomposes. Humus soil is rich in nutrients and helps improve soil structure, drainage, and fertility. It is important for healthy plant growth and biodiversity in the soil.
The least fertile layer of soil is usually the bedrock layer, which is the solid rock beneath the soil horizons. Since bedrock contains few nutrients and is not suitable for plant roots to penetrate, it is not conducive to plant growth.
Topsoil contains the most humus because it is the uppermost layer of soil that is rich in organic matter from decomposed plants and animals. This organic matter accumulates in the topsoil over time, contributing to its fertility and nutrient content.
The topsoil layer contains the greatest amount of decayed organic material, also known as humus. This layer is rich in nutrients and organic matter, making it ideal for plant growth.

All soil contains some humus. If it doesn't it is not soil.
The C and R horizon
Soil that contains humus is known as humus soil. Humus is a dark, organic material that forms when plant and animal matter decomposes. Humus soil is rich in nutrients and helps improve soil structure, drainage, and fertility. It is important for healthy plant growth and biodiversity in the soil.
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.
bed rock
Humus is located in the top layer of soil. It is a type of organic soil matter and aids in nutrition retention in the soil.
the O-Horizon is the topmost soil so it has the most humus
The least fertile layer of soil is usually the bedrock layer, which is the solid rock beneath the soil horizons. Since bedrock contains few nutrients and is not suitable for plant roots to penetrate, it is not conducive to plant growth.
