In the UK alone some 100
thousand cubic metres of peat is used each year in commercial
mushroom growing. Now the rapid depletion of the world?s peat
resources, home to a number of rare plant and animal species, could
be significantly reduced thanks to a new substitute product
developed by scientists at the University of Warwick's Horticulture
Research International (HRI).
The substitute material, commonly referred to as coal tailings,
is a waste product from the mining industry. Typically it can be
used to replace up to 30% of the dark peat used in mushroom growing
and continuing trials show that it produces good yields of high
Worldwide we consume in excess of 7 million tonnes of mushrooms
a year; Warwick's research means we can now continue to enjoy our
mushrooms at considerably less threat to our environment.
