    Topsoil and subsoil

    BS3882 Testing -
    Topsoil & Subsoil Characterisation Services

    SOCOTEC's experienced advanced chemistry & research team provides expert analysis of topsoil and subsoil.

    Quality topsoil and subsoil should provide good anchorage for plant roots, slowly release nutrients, provide oxygen for plant uptake and drain excess water while retaining enough moisture to sustain plant health during dry periods.

    Assessing the quality of topsoil and subsoil is an important aspect of civil engineering, public and private landscaping or remediation projects, public spaces and the farming community.

    SOCOTEC assesses topsoil and subsoil quality in accordance with the current versions of BS3882 (Specification for Topsoil and Requirements for Use) and BS8601 (Specification for Subsoil and Requirements for Use) which specify requirements for topsoil and subsoil that is moved or traded. The standards aim to ensure soils are fit for use, safe and healthy for humans, vegetation and the broader environment.
