Definition of topsoil

Categorized under "General"

Definition as written by Linnea:

The soil at the surface of the earth, wherein plants are grown. It is the soil with the most organic matter in it.

Definition as written by Terry:

Topsoil is comprised of three basic groups of organic matter - sand, clay particles and humus

A high proportion of clay particles will create heavy soil that is difficult for air and water to pass through; too much sand will create soil that drains too quickly and cannot retain moisture or nutrients. Either problem can be remedied by amending the soil with humus or compost material.
