Description

Composed of re-purposed, single source, screened natural topsoil, usually of sandy clay loam classification with added PAS 100 compost, 20% by volume. BLS 20 is a natural topsoil with 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 installed at depths no greater than 350–400 mm; greater depths should be built up with Boughton Loam's 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 the manufacturer's BLS 2 topsoil which has a lower organic matter and therefore creates a more stable tilth for lawns. Boughton Loam can provide additional advice if needed on how best to specific and install this topsoil.
