BLS 20 – Natural Topsoil

BLS20 is a repurposed, single source, screened, natural topsoil, usually of sandy clay loam classification with added PAS 100 compost, 20% by volume. This topsoil has boosted organic matter content, has excellent moisture and nutrient retention capabilities. It is a premium soil best suited to large scale, ground level, planting projects.

BLS 20 should be installed at depths no greater than 350-400mm, greater depths should be built up with our subsoil products. BLS 20 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.

For lawns please refer to our BLS 2 topsoil which has lower organic matter content, and therefore creates a more stable tilth for lawns. Boughton Loam can provide additional advice if needed on how best to specify and install this topsoil.
