The biome that contains the most humus is typically the temperate forest. These forests, characterized by their moderate climate and seasonal changes, support a rich diversity of plant life that contributes to a thick layer of organic matter. The decomposition of fallen leaves and other plant materials creates a nutrient-rich topsoil with high humus content, which is essential for soil fertility and ecosystem health.
The biome characterized by soil rich in humus is primarily the temperate deciduous forest biome. This type of soil is dark, fertile, and nutrient-rich due to the decomposition of organic matter from the forest vegetation. Humus-rich soil is important for supporting diverse plant and animal life in this biome.

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 Fertile soil contains lots of microorganisms which decompose the complex dead bodies of animals and plants into simpler substance called Humus.
topsoil.
soils have different layers present in it as the depth increases. These layers are called horizons. Humus as we all know is present in the top layer of the soil,which is several inches in thickness and is called A horizon.

All soil contains some humus. If it doesn't it is not soil.
