Topsoil contains organic matter (humus)
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.

The formation of complex organic matter in soil is called Humus
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.
All soil contains some humus. If it doesn't it is not soil.

The C and R horizon
The Fertile soil contains lots of microorganisms which decompose the complex dead bodies of animals and plants into simpler substance called Humus.
podzolic do not have much fertile humus. this causes a bright brown colour.
how does the presence of humus affect soil

Of course it does! Humus is made of dead stuff and orginc matter and this helps the soil add more nutrients.
