What types of materials make up the o horizon?
The O horizon, also known as the organic horizon, is composed of organic materials such as decomposing plant litter (leaves, twigs), animal remains, and living organisms like insects and microorganisms. It is the topmost layer of the soil profile and plays a critical role in nutrient cycling and soil fertility.
Which materials typically make up the A horizon in soil?
The A horizon, or topsoil, is typically composed of a mixture of mineral particles (sand, silt, clay), organic matter (humus), water, and air. The organic matter in this layer is a key component that influences soil fertility and overall soil health.
What are the 4 soil horizons?
The four soil horizons are O horizon (organic layer), A horizon (topsoil), B horizon (subsoil), and C horizon (parent material). These horizons make up the soil profile and each has distinct characteristics based on their composition and arrangement.
What are the Five soil horizons?
The five soil horizons are O horizon (organic matter), A horizon (topsoil), E horizon (eluviated or leached layer), B horizon (subsoil), and C horizon (parent material). These horizons collectively make up the soil profile and influence soil characteristics and fertility.
What are the 6 layers of a soil profile?
Organic- mostly made up of plant and animal decomposers Topsoil-Made up of earthworms and fungi Eluviation- Made up of sand and silt Subsoil- Made up of clay Regolith-The layer where large rocks are found

What materials makes up horizon B in a soil?
it is generally the accumulation of nutrients leached from the top soil and also few amount of organic matter

Which material Typically make up A horizon in soil?
Topsoil is another name for soil found in the A horizon. It is made up of minerals and is usually coarser and has less clay than the other horizons.

What soil horizon that is made up of partially broken bedrock?
Horizon C
What is a group of soil called?
A group of soil is called a soil horizon. Soil horizons are distinct layers that make up the soil profile, each with its own unique characteristics and composition.
The soil horizon that is made up of partially broken bedrock is?
The soil horizon that is made up of partially broken bedrock is known as the C horizon. It is located directly beneath the B horizon and consists of weathered rock fragments intermingled with some organic material.
