Application

Suitable for general landscaping and planting of hardy nursery stock and amenity grassland. Typical uses include: General landscaping; landscape renovation; construction.

Description

Composed of re-purposed, single source, unscreened, as dug natural topsoil, usually of sandy/ clay loam classification. BL 1 is a natural as dug topsoil with 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. BL 1 is unscreened and so its consistency can vary.  BL 1 should be installed at depths no greater than 350–400 mm; greater depths should be built up with Boughton Loam's subsoil products.


BL 1 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 specific and install this topsoil.
