[citation needed] Peat is discouraged as a soil amendment by the Royal Botanic Gardens, Kew, England, since 2003. [32] While bark or coir-based peat-free potting soil mixes are on the rise, particularly in the UK, peat is still used as raw material for horticulture in some other European countries, Canada, as well as parts of the United States.
The use of peat is controversial since the harvesting of peat moss from peatlands (which includes unique habitats such as bogs and fens) can degrade these peatlands. Peatlands are home to a diverse range of plant and animal species. Peat also has a very slow accumulation rate, as little as 1mm per year, so they take a long time to regenerate.
Ericaceous bed made from peat blocks. An ericaceous bed is a bed (or garden) with acidic and often nutrient-poor soil such as ericaceous compost and different types of peat. The pH of the soil is typically between 4.5 and 6. The purpose is to grow a number of garden plants which require (or thrive best in) acidic soil.
It can also lower the pH of the soil surface, making it useful as a mulch under acid loving plants. However, peat bogs are a valuable wildlife habitat, and peat is also one of the largest stores of carbon (in Britain, out of a total estimated 9952 million tonnes of carbon in British vegetation and soils, 6948 million tonnes carbon are estimated ...
While adding a soil conditioner to crops or a garden can seem like a great way to get healthier plants, over-application of some amendments can cause ecological problems. For example, salts, nitrogen, metals and other nutrients that are present in many soil amendments are not productive when added in excess, and can actually be detrimental to ...
It is therefore important to protect this areas and restore degraded areas. To conserve, restore and improve management of peat lands is a cost efficient and relatively easy way to maintain ecosystem services. However, these the ecosystem services are not priced in a market and do not produce economic profit for the local communities.
