BLS 40 – Natural Topsoil

BLS 40 is a repurposed, single source, screened, natural topsoil, usually of sandy/clay loam classification with added PAS 100 compost, 40% by volume. This topsoil has boosted organic matter content, excellent moisture and nutrient retention capabilities. It is a premium soil best suited to specific planting projects such as raised & ground level vegetable gardens, fruit production, both soft and hard.

BLS 40 should be installed at depths no greater than 350-400mm; the greater depths should be built up with our subsoil products. BLS 40 is well suited to projects where permanent irrigation is not specified because of its good water retention properties, although with vegetable and fruit products we would always recommend some form of regular irrigation.

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.
