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 bottom layer of soil?
loam
Horizontal layer of soil?
A horizons are formed by the accumulation of organic matter in the soil, resulting in a dark layer rich in nutrients. They are usually located at the top of the soil profile and are important for supporting plant growth. The thickness and characteristics of the A horizon can vary depending on factors such as climate, vegetation, and land use.
What are three horizones of soil?
The first layer of soil is called the O Horizon, it is made of primarily humus. The second layer is the A horizon, this is the topsoil. Then there comes the E layer which is the eluvation layer. Next comes the B horizon which is the subsoil, then there is the C horizon which is the regolith, then the final layer is the R layer which is bedrock.
