Yes, topsoil has a higher humus content than subsoil. It tends to be the layer of the soil food web where above and below ground organisms such as bacteria, beetles, and earthworms live and die. The death and the resulting decay of these organisms contribute to the build up of organic matter. Another word for humus in fact is organic material.

Yes topsoil has more fertility and humus than subsoil.
Topsoil typically has the largest particle size among humus, subsoil, and topsoil. This layer is the uppermost layer of soil and is composed of a mix of organic matter, minerals, and nutrients. Humus is a component found within topsoil that is made up of fully decomposed organic matter, while subsoil is found beneath the topsoil and can have a finer texture due to lower organic content.

Topsoil generally contains more humans compared to subsoil, as it is the uppermost layer where most human activity and cultivation takes place. Subsoil is typically found below the topsoil and contains fewer human interactions or disturbances.
the O-Horizon is the topmost soil so it has the most humus
Soil is typically classified into three main layers: topsoil, subsoil, and bedrock. Topsoil is the uppermost layer where most plant roots grow, subsoil contains less organic matter and nutrients, and bedrock is the solid rock layer beneath the soil.
no it is found in the topsoil or a horizon
The layer of soil lacking humus and fertility is called the subsoil. Subsoil is usually low in organic matter and nutrients, making it less suitable for plant growth compared to topsoil. It often requires amendments or management practices to improve its fertility.
topsoil is near the roots of trees and subsoil is underneath the roots of trees
