[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.
[42] [43] An estimate derived from the digital soil database of Russia at a geographical scale of 1:5 million, [44] indicates that the area of soils with a peat depth of more than 30 cm is nearly 2210×10 3 km 2. Approximately 28% occurs in the zone of seasonally frozen soils, nearly 30% in the zone of sporadic and discontinuous permafrost, and ...
Peat formation typically initiates as a paludification of a mineral soil forests, terrestrialisation of lakes, or primary peat formation on bare soils on previously glaciated areas. [3] A peatland that is actively forming peat is called a mire .
Peatland as an ecosystem is important for regulating soil quality. When the peat covering Sphagnum layer is degraded, the remaining bare peat soil releases sediment to water streams, which pollutes and reduces biodiversity of rivers and water reservoirs. [20] Additionally trough wind and water erosion carbon can be released if the peat is blank ...
A fen is a type of peat-accumulating wetland fed by mineral-rich ground or surface water. [1] [2] It is one of the main types of wetland along with marshes, swamps, and bogs. Bogs and fens, both peat-forming ecosystems, are also known as mires. [2] The unique water chemistry of fens is a result of the ground or surface water input.
In addition, bogs, like all wetlands, develop anaerobic soil conditions, which produces slower anaerobic decay rather than aerobic microbial action. Peat moss can also acidify its surroundings by taking up cations, such as calcium and magnesium, and releasing hydrogen ions. Under the right conditions, peat can accumulate to a depth of many meters.
Winter may not be officially here on the calendar, but much of the country is already getting a wintry chill. As many drivers make their way home from Thanksgiving travels, most of the north and ...
Soil structure is essential to soil health and fertility; soil structure decline has a direct effect on soil and surface food chain and biodiversity as a consequence. Continued crop cultivation eventually results in significant changes within the soil, such as its nutrient status, pH balance, organic matter content, and physical characteristics ...
