Question

What is meant by sub-soil?

please help me

Answer 1

Explanation:

Subsoil is the layer of soil under the topsoil on the surface of the ground. ... Although by no means sterile, subsoil is relatively barren in terms of soil organisms compared to humus-rich topsoil

Answer 2

The layer just under the top-layer (A horizon) is called B horizon. This is also known as Sub-Soil. this layer is slightly harder and more compact. it has very little humus or organic matter. this layer is rich in soluble minerals and iron oxide and is light in colour.
