Talk:Peat

no more fens

it says on the article for fens, that they are often confused with bogs but are not actually bogs, so i removed fens from the synonym list in the beginning of the article.

carbon content high or low?

In the section "Fires" it says (first sentence): Peat has a high carbon content and can burn under low moisture conditions.

In the section "Tissue Preservation" it says (last sentence): Peat represents the initial stage of coal formation, so its carbon content is low.

I find this confusing - could anybody in the know please clarify this?

Characteristics/uses

There are three overlapping sections on characteristics and uses of peat in this article. I'm planning to try resolve this. TatjanaClimate (talk) 16:09, 5 July 2023 (UTC)

Misleading citation

The article reads: "Peat can store nutrients although it is not fertile itself – it is polyelectrolytic with a high ion-exchange capacity due to its oxidized lignin.[citation needed] Peat is discouraged as a soil amendment by the Royal Botanic Gardens, Kew, England, since 2003.[23]"

This snippet of the article claims that peat is not fertile, then cites the RBG who "discourage" it's use as a soil ammendment. The implication is that peat is a bad soil ammendment, but the content of the citation suggests that it is actually discouraged from use for a variety of political reasons that have nothing to do with peat being an effective amendment. Seems like there was a bit of a bait and switch with the citation that brings into question the downplaying of peat as a valid amendment. 2603:8080:2B00:11D4:1805:3AFF:FEA6:D3AD (talk) 01:24, 3 September 2024 (UTC)

I don't really see the problem. The first sentence has a clear [citation needed] tag which shows that there's not a source for the statement. The second sentence is unrelated and has a separate citation of its own. Each sentence in that Agriculture paragraph gives a separate piece of information related to peat and agriculture.

Page is lacking scientific references on peatland restoration, see suggested edit below:

Restoration section:

The current section on peatland restoration is limited. Suggested improvements:

• Include section on ecological restoration methods

Ecological restoration techniques can be applied to restore the functions of post-extraction peatlands, with a particular emphasis on the return of biodiversity, hydrology, and carbon sequestration.  

The Moss Layer Transfer Technique

The main objective of peatland restoration after horticultural Peat extraction is to re-establish self-regulatory mechanisms that will lead back to a naturally functioning ecosystem, including its ability to accumulate Peat.  

The Moss Layer Transfer Technique (MLTT) restoration technique was developed through an extensive research program. It is based on two actions:  

• the rewetting of the site, which is achieved by blocking the drainage ditches that were dug to allow for the extraction of Peat;

• the reintroduction of peatland plants on the surface of the site, combined with various techniques to improve conditions for plant establishment (e.g. straw mulch)

These plants are collected from a donor site. The donor plant material is chopped and transferred onto the surface to restore, in a 1:10 ratio (1 m² of donor material restores 10 m² of peatland area).

Restoring peatlands after peat extraction is essential to reestablish their role as carbon sinks within one to two decades, capturing and storing atmospheric carbon through sequestration [1].

Return of the Biodiversity: Active peatland plant reintroduction successfully re-establishes typical plant communities within 5 years after restoration [2]. These support the return of animal, insect and bird communities found in undisturbed similar environments. The presence of pools in restoration projects increases the biodiversity by providing a variety of microhabitats.

Further additions to outdated information about Peat use, peatland science and country-specific details

The section on Canada is lacking detail and appears out of date. Suggested additions below:

• Correction: “There are 294 million acres of peatland in Canada, with approximately 43,500 acres in production and another 34,500 acres involved in past production.” - out of date information on the peat extraction industry. Suggestion to replace with “In 2023, the total Canadian Peat Industry footprint (all areas opened for Peat extraction since the beginning of industrial operations, around 1930) covers 36,032 ha. That area represents 0.03% of Canada’s overall peatland area. As of 2023, 60% of the industry footprint was under extraction and 40% was in post-extraction, which includes 29% restored or reclaimed and 11% either converted to other land-use (like agriculture) or waiting to be restored. That means 72% of the post-extraction areas have been restored or reclaimed. Each year, approximately 11.3 million cubic metres (or 400 million cubic feet) of Peat are extracted, primarily for use in professional growing mixes and potting soils.”

• Peat extraction in Canada represents only 1% of peatland disturbance from human activities (24,964 ha), compared to other disturbances such as agriculture (63% or 1,315,373 ha), mining (18% or 370,000 ha), hydropower reservoirs (12% or 245,000 ha), and forestry (3% or 69,700 ha) [1].

History of Peat extraction in Canada:

• Unlike some European countries, Canada has had a short history of peat extraction in the country, with the Canadian peat extraction industry only commencing approximately a century ago.

Peat uses for horticultural purposes in Canada started approximately 100 years ago. Before World War II, most of the Peat used in North America came from Europe, particularly from the Scandinavian countries, the Netherlands and Germany. As a result of the war, traditional sources of Peat were interrupted and efforts to find local sources triggered the modern era of Peat extraction in Canada, mainly in Alberta, Manitoba, Québec and New Brunswick initially.    

Over the years, Canadian companies became the main suppliers of Peat in North America, in its raw form but with various fibrosity levels. Initially, Peat was used in horticulture, supporting the floricultural and mushroom growing segments but also for animal bedding, packing, and insulation material. Extraction consisted of cutting blocks of Peat by hand with shovels and stacking them for drying, a method that had been used for centuries across Europe. The blocks were then cut into chips at the processing plant and pressed into bales. Increased productivity was then achieved by importing cutting machines from Europe.    

In terms of geographical expansion, what had started as a Peat extraction industry in four provinces, slowly but surely expanded to nine over the next decades, to include, Saskatchewan, Ontario, Nova Scotia, Prince Edward Island, and Newfoundland, ensuring a more efficient distribution over the North American continent.  

At the end of the 1960’s, early 1970’s three major changes happened that contributed to the industry’s growth. First, Canadian Peat producers gradually abandoned the traditional block cutting method in favour of the milling method using vacuum harvesting machines. Second, a number of Peat producers and various stakeholders successfully conceived and introduced ready-to-use potting soils and mixes intended for the various horticultural markets, mainly the floriculture market and home gardening. Third, plant operations and bale handling were greatly facilitated by increased automation.  

The 1970’s to the 1990’s was thus a period of growth and product diversification to serve a very rapid expansion of various usages for Peat and Peat-based growing media in North America.    

The section on 'Protection' is lacking detail and appears out of date. Suggested additions below:

Beginning in the late 20th century, international peatland policy increasingly shifted toward concepts of “wise use” and responsible management, balancing conservation, restoration, and sustainable economic use.

Research on peatlands and climate change expanded significantly during the 2000s and 2010s. In 2008, IPS published Peatlands and Climate Change, summarizing scientific knowledge on peatlands’ role in greenhouse gas dynamics, carbon storage, and land management. In 2010, IPS released its Strategy for Responsible Peatland Management, promoting approaches that integrate environmental, social, and economic considerations.

In many countries, peatland management now includes requirements for environmental assessment, water management planning, progressive rehabilitation, and ecological restoration following peat extraction. In Canada, for example, the horticultural peat industry has supported peatland restoration research since the early 1990s through collaborations between industry, universities, and research organizations. One such example is the Peatland Ecology Research Group (PERG) (https://www.gret-perg.ulaval.ca/en/publications) who have over 400+ publications related to peatland science and ecological restoration. Restoration techniques developed in Canada have been adopted internationally and have demonstrated the ability to re-establish peat-forming vegetation and ecosystem functions on previously harvested peatlands.  

At the same time, some countries have introduced restrictions or bans on peat extraction due to environmental concerns. In some regions, peat extraction has been restricted or phased out, particularly for energy use and horticultural applications. Policies vary significantly by country, ranging from outright bans to regulated extraction systems combined with restoration requirements.  

The section on 'Uses' is lacking detail and appears out of date. Suggested additions below:

Agriculture: (really should be titled 'Agriculture & Horticulture' - as peat is predominately used in horticultural applications rather than traditional agriculture applications)

Peat is widely used in horticulture and agriculture as a growing medium and soil amendment due to its high water-holding capacity, porosity, low bulk density, sterility, and ability to support healthy root development. Sphagnum peat moss is particularly valued in commercial horticulture because it provides consistent physical properties and can be blended with other materials to optimize aeration, drainage, nutrient retention, and moisture management for different crops.

Peat is commonly used in the production of vegetables, berries, mushrooms, ornamental plants, tree seedlings, and greenhouse crops. In container growing systems and controlled environment agriculture, peat-based growing media are often used because they provide a stable and predictable root environment.

During the 2000s and 2010s, interest in peat-free growing media increased in some regions, particularly in the United Kingdom, where organizations such as the Royal Botanic Gardens, Kew encouraged reducing peat use in gardening.[32] Alternative materials include composted bark, wood fibre, coconut coir, compost, and green waste-derived products.

However, replacing peat entirely remains technically challenging for some horticultural applications because alternative materials may differ in consistency, nutrient dynamics, salinity, water retention, disease suppression, or availability. Many peat alternatives also have environmental trade-offs associated with transportation, processing, land use, or resource inputs.

Life-cycle assessment (LCA) of growing media has become an active area of research, as scientists and industry groups attempt to better understand the environmental impacts, trade-offs, and performance characteristics of peat and alternative substrates across their full supply chains. Results vary significantly depending on system boundaries, transportation distances, processing methods, land-use assumptions, crop performance, product lifespan, and end-of-life treatment. Recent studies have highlighted that different growing media components, including peat, coir, bark, wood fibre, and mineral substrates, can each present distinct environmental advantages and disadvantages depending on the application and assessment methodology used. Ongoing research initiatives, including collaborative work by the Soilless Substrates Science (S3) research team (https://www.soillesssubstrates.org/) in the United States, continue to evaluate the environmental performance and sustainability of commonly used growing media components through comparative life-cycle analysis.
