What is Topogenous peat?

What is Topogenous peat?

topogenous mire (topogenous peat) A type of bog that forms under climatic conditions of reduced rainfall, with consequent lower humidity and summer drought, which restrict the growth of Sphagnum to areas where precipitation is concentrated (e.g. valley bottoms).

What are the three types of peat?

Types of peat material 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. Phragmites peat are composed of reed grass, Phragmites australis, and other grasses.

Are bogs and peatlands the same thing?

Because all bogs have peat, they are a type of peatland. As a peat-producing ecosystem, they are also classified as mires, along with fens. Bogs differ from fens in that fens receive water and nutrients from mineral-rich surface or groundwater, while bogs receive water and nutrients from precipitation.

Why are peatlands acidic?

Acidity in peatlands is a by-product of microbial decay processes, cation exchange, and input of acids from the atmosphere. In the first case, bacteria and fungi breakdown dead plant and animal material and in the decay process acid is released into the surrounding environment.

What are the 2 types of peat?

There are two main types of peatlands: bogs and fens. They differ on the basis of their vegetation, hydrology and water chemistry.

What is another name for peat?

What is another word for peat?

What is a fen bog?

A fen is a type of peat-accumulating wetland fed by mineral-rich ground or surface water. It is one of the main types of wetlands along with marshes, swamps, and bogs. Bogs and fens, both peat-forming ecosystems, are also known as mires.

Are all wetlands peatlands?

Some wetlands accumulate peat (partially-decomposed organic matter) and are called peatlands. Bogs and fens are the dominant peatland classes in Alberta, although some swamps and marshes can also accumulate peat. In contrast, shallow open water wetlands and many marshes and swamps do not accumulate peat.

What pH is peat?

Peat soil has a pH ranging from 3.7-5.2 with an average pH of 4.5 (acidic), does not contain pyrite, ash around 1:13% – 43.88%, and the content of organic C ranges from 32.55% – 57.35%.

Is peat soil acidic or alkaline?

acidic
As noted above, peat Moss has an acidic pH, generally in the range of 4.4 (a pH of 7 is neutral; higher pH numbers indicate alkaline soils).
