Peat bogs are an important carbon store, so mushroom growers are searching for a way to grow their produce on other substrates
In a huge industrial shed on Leckford Estate, a farm owned by the supermarket Waitrose in a beautiful part of southern England, a revolution is stirring in the world of mushroom growing. UK production of this crop relies on peat, the incredibly carbon-rich organic matter found in bogs and fens across the country. Peatland contains so much carbon, it is sometimes described as “the UK’s rainforests”.
That is why the UK government has promised to restore 280,000 hectares of peatland in England alone by 2050, to help meet its climate change goals.
