The first layer of soil is topsoil. Topsoil is the moste nutricious layer and takes 500 years to replace just 1 inch of new topsoil. Make sure you take good care of your soil. Next comes subsoil. Subsoil is the seconed layer of soil and thats the layer of soil that the roots lock into. After that comes parent material but it is also called bedrock. Bedrock is the last layer of soil. It is the part that makes the new layers of soil. It is also hard and rocky and is the largest layer of soil.

The first layer of soil is topsoil. This layer has the most nutritious but the hardest to replace. This is where our crops grow. Subsoil is the second layer. This layer has choped up rocks. The roots from plants will be found here.The last layer is parent material/bedrock.This all the basic stuff to make new soil.
