Describes requirements for the classification, composition and use of subsoils that are moved or traded for creating soil profiles intended to support plant growth.

This British Standard specifies requirements for the classification, composition and use of subsoils that are moved or traded for creating soil profiles intended to support plant growth. The standard is not applicable to topsoil, or to subsoil that is to remain in situ. It is not intended to preclude the use of subsoil that is already on site and suitable for its intended purpose. This standard specifies requirements for multipurpose subsoil, which is fit for the majority of needs, and also specific purpose subsoils that are acidic or calcareous, for specialist use where acidic or calcareous soil profiles are required. It also specifies requirements for sampling and analysis of subsoil.
