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.
What else can I help you with?
Why does top soil have most 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.
Which layer of soil is the most newly formed?
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.
What is the second layer of organic soil?
The second layer of organic soil is typically referred to as the topsoil. Topsoil contains a mix of organic matter, minerals, and nutrients that support plant growth. It is the most fertile layer of soil and is vital for healthy plant development.
What layer of the soil contains the most nutrients?
The topsoil layer contains the most nutrients. This layer is rich in organic matter and nutrients that plants need to grow.
How many layers of soil?
3 layers of different kinds of soil is you count humus,5, (humus, topsoil, midsoil, poor soil, bedrock, you can call it 3 though, humus isn't actual soil its dacayed plants and animals)
Which contains the most humus?

Why does top soil have most humus?

Which soil layer contains the most humus?
the O-Horizon is the topmost soil so it has the most humus
Which 2 layers of the soil are least likely to contain humus?
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.
Which horizon contains the most humus?

Which layer of the earth contains the most oxygen?
The troposphere layer contains the most oxygen. Stratosphere contains most of the ozone i.e. a form of oxygen.
Why does soil horizon A have the most Humus?
The Fertile soil contains lots of microorganisms which decompose the complex dead bodies of animals and plants into simpler substance called Humus.
What is the second layer of organic soil?
The second layer of organic soil is typically referred to as the topsoil. Topsoil contains a mix of organic matter, minerals, and nutrients that support plant growth. It is the most fertile layer of soil and is vital for healthy plant development.
