Peat material is either fibric, hemic, or sapric. Fibric peats are the least decomposed and consist of intact fibre. Hemic peats are partially decomposed and sapric are the most decomposed. [22] Phragmites peat are composed of reed grass, Phragmites australis, and other grasses. It is denser than many other types of peat.
These materials include muck (sapric soil material), mucky peat (hemic soil material), or peat (fibric soil material). Many Histosols show aquic conditions or artificial drainage, [3] some (Folists in Soil Taxonomy and Folic Histosols in WRB) developed under terrestrial conditions.
Peat is also high in non-humified organic matter that needs to be reduced to produce a high quality product. The benefit of peat is that it is usually 2-3 times higher in fulvic acid content, which are the low molecular weight fractions of humic acid that are high in oxygen containing functional groups and soluble at a low pH of <1.
- Type 10.3 "Peat sapric soils" (Polish: Gleby torfowe saprowe; WRB: Sapric or Fibric Sapric or Hemic Sapric or Limnic Sapric Histosol; ST: Typic or Hemic or Limnic or Fluvaquentic or Terric Haplosaprists) - Type 10.4 "Organic detritus soils" (Polish: Gleby organiczne ściółkowe; WRB: Folic or Folic Leptic Histosol; ST: Typic or Lithic ...
Humic acid isolated from peat Fulvic acid isolated from peat. Humic substances (HS) are colored relatively recalcitrant organic compounds naturally formed during long-term decomposition and transformation of biomass residues. The color of humic substances varies from bright yellow to light or dark brown leading to black.
Muck farming on drained swamps is an important part of agriculture in New York, Ohio, Illinois, Indiana, Michigan, Wisconsin, and Florida, where mostly vegetables are grown.
Luhasoo bog in Estonia.The mire has tussocks of heather, and is being colonised by pine trees.. This is a list of bogs, wetland mires that accumulate peat from dead plant material, usually sphagnum moss. [1]
By allowing oxygen to enter the peat column within a mire, drainage disrupts the balance between peat accumulation and decomposition, and the subsequent oxidative degradation results in the release of carbon into the atmosphere. [53] As such, drainage of mires for agriculture transforms them from net carbon sinks to net carbon emitters. [1]
