What is peat accumulation?
Peat (/piːt/), also known as turf (/tɜːrf/), is an accumulation of partially decayed vegetation or organic matter. Peat forms in wetland conditions, where flooding or stagnant water obstructs the flow of oxygen from the atmosphere, slowing the rate of decomposition.
What is peat and why is it used?
Peat is used for domestic heating purposes as an alternative to firewood and forms a fuel suitable for boiler firing in either briquetted or pulverized form. In horticulture, peat is used to increase the moisture-holding capacity of sandy soils and to increase the water infiltration rate of clay soils.
What is peat stage?
Peat formation is the result of incomplete decomposition of the remains of plants growing in waterlogged conditions. This may happen in standing water (lakes or margins of slow flowing rivers) or under consistently high rainfall (upland or mountain regions).
What are two 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.
How long does it take peat to develop?
Peat, or turf, as it is often referred to in Ireland, is a type of soil that contains a high amount of dead organic matter, mainly plants that have accumulated over thousands of years. It takes approximately a staggering 10 years for 1cm of peat to form!
How do you get out of a peat bog?
The trick to walking across a peat bog is to pick your way across by linking up the firmer spots that will hold your body weight while avoiding the wetter spots where you will sink.
Is peat good or bad?
Many gardeners trust peat as a growing medium. But it’s not always ideal. It is a poor mulch, quickly dries out, and is easily blown away. Peat compost alternatives have been refined over many years to provide a fantastic growing medium.
When was peat first used?
Peat has been used as a fuel in Ireland for many centuries. Evidence suggests it was used as early as the seventh century. By the 19th century, turf had become one of the main sources of fuel in Ireland, alongside coal.
What is the problem with peat?
The carbon in peat, when spread on a field or garden, quickly turns into carbon dioxide, adding to greenhouse gas levels. 3. The unique biodiversity of peat bogs is lost. Rare birds, butterflies, dragonflies and plants disappear.
Is peat decomposed?
Peat is the surface organic layer of a soil that consists of partially decomposed organic matter, derived mostly from plant material, which has accumulated under conditions of waterlogging, oxygen deficiency, high acidity and nutrient deficiency.
Can you drown in a peat bog?
The bog is called a quaking bog to indicate the instability of the surface, which will sink slightly beneath a weight. It is even possible to break through the vegetation into the water beneath. Both people and animals have drowned this way. Nonfloating bogs may also quake if the peat is thick and spongy.
