| To address
topsoil shortfalls, a topsoil substitute may be manufactured
from soil-forming materials
Many development sites do not possess
adequate topsoil for soft landscaping. This is commonly
because site topsoil has been stripped and exported
during previous development.
In the past, topsoil shortfalls were
typically addressed by imported soils. Increasingly,
this option is becoming less viable, particularly where
Greenfield sites are not developed to provide a source
of topsoil. Furthermore haulage costs or poor quality
of local topsoils can also prohibit importation.
Where necessary, a topsoil substitute
may be manufactured by blending a suitable mineral base
with appropriate source(s) of organic matter and other
additives, depending on the nature of the mineral material.
The topsoil can be manufactured in-situ or ex-situ and
spread into its final location.
