Our topsoil is excavated from our surface mine which was previously farm land. We offer field grade topsoil and screened topsoil. Field grade topsoil is straight out of the field, just like it sounds. This material may contain a little debris and a few larger chunks. Screened topsoil is the same soil material as the field grade but we process it through a machine that actually sifts the topsoil and removes any debris that is larger than a golf ball. Because of this process, this material is a little costlier than the field grade.
