BL 1 – Natural Topsoil

BL1 is a repurposed, single source, unscreened, as-dug, natural topsoil; usually of sandy/clay loam classification. This topsoil contains good levels of natural retained organic matter content, has excellent moisture and nutrient retention capabilities.

A natural soil best suited to large scale, ground level, planting projects for hardy stock, amenity grasslands and landscape renovation works. BL1 is unscreened so its consistency may vary. This topsoil should be installed at depths no greater than 350-400mm; the greater depths should be built up with our subsoil products.

Bl1 is well suited to projects where permanent irrigation is not specified because of its good water retention properties. For plant establishment, temporary irrigation maybe required.

Boughton Loam can provide additional advice if needed on how best to specify and install this topsoil.
