[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.
A peatland is a type of wetland whose soils consist of organic matter from decaying plants, forming layers of peat. Peatlands arise because of incomplete decomposition of organic matter, usually litter from vegetation , due to water-logging and subsequent anoxia . [ 1 ]
Water retention curve is the relationship between the water content, θ, and the soil water potential, ψ. The soil moisture curve is characteristic for different types of soil, and is also called the soil moisture characteristic. It is used to predict the soil water storage, water supply to the plants (field capacity) and soil aggregate stability.
Peat cutting, while much more common in bogs, does happen in fens. Peat cut from fens has many uses, including burning as a fuel. [5] Pollutants can alter the chemistry of fens and facilitate invasion by invasive species. [5] Common pollutants of fens include road salts, nutrients from septic tanks, and runoff of agricultural fertilizers and ...
Soil color, while easily discerned, has little use in predicting soil characteristics. [109] It is of use in distinguishing boundaries of horizons within a soil profile, [ 110 ] determining the origin of a soil's parent material , [ 111 ] as an indication of wetness and waterlogged conditions, [ 112 ] and as a qualitative means of measuring ...
moss bog) is a peat-forming ecosystem found in several northern climates, most commonly in Arctic and boreal areas. Muskeg is approximately synonymous with bog or peatland, and is a standard term in Canada and Alaska. The term became common in these areas because it is of Cree origin; maskek (ᒪᐢᑫᐠ) meaning "low-lying marsh". [1]
Organic soil material has an organic carbon content (by weight) of 12 percent or more (Soil Taxonomy) or 20 percent or more (WRB). These materials include muck (sapric soil material), mucky peat (hemic soil material), or peat (fibric soil material).
Pocosin is a type of palustrine wetland with deep, acidic, sandy, peat soils. [1] Groundwater saturates the soil except during brief seasonal dry spells and during prolonged droughts. Pocosin soils are nutrient-deficient (oligotrophic), especially in phosphorus. [2]
