The first reference to peat is Pliny the Elder’s description of “combustible earth” for heating food (AD. The area occupied by peat deposits and bogs throughout the world is approximately 350 million hectares (ha), of which approximately 100 million ha are commercially important. peat bog, peatbog; peaty… Some peat deposits were formed during periods between glaci-ations or became superimposed by loose deposits of varying thickness as a result of change in the level of erosion. Silty soil is composed of clay, mud, or small rocks deposited by a lake or river. The most extensive peat deposits are found in Canada and Russia, with significant peatlands also in N Europe and NE China. 2.1 Definition of Peat 2.1.1 In Scotland, peat is defined as “an organic soil which contains more than 60 per cent of organic matter and exceeds 50cin thickness”m (Macaulay Institute, 1984). Pressed peat briquettes are used in the USSR and Ireland for nonindustrial purposes. The type of peat bog is the primary unit of classification (Figure 1). peaty soil definition. The color varies from yellow or brown to black. A fibrous mass of organic matter in various stages of decomposition, generally dark brown to black in color and of spongy consistency. peat (countable and uncountable, plural peats) Soil formed of dead but not fully decayed plants found in bog areas, often burned as fuel. For example, weakly decomposed high-moor peat. As known, soil compaction harms gardens while reducing water absorption and affecting plant growth adversely. peaty or organo mineral soils (km2) Deep peaty or organic soils (km2) Peat-forming bogs (km2) Peat-fens (km2) England 7,386 6,799 2,727 80 Wales 3,592 706 718 62 Northern Ireland 1,417 2,064 1,069 30 Scotland 34,612 17,269 17,720 86 Total area 47,007 26,838 22,775 258 UK area cover 19.3% 11% 9.35% 0.11% * Either existing or planned for restoration Kids Definition of peat. The organic matter in peat consists of plant residues that have undergone varying degrees of decomposition. This type of soil started forming millenniums ago, aided by the rapid melting of glaciers. They are found in peatlands (also called bogs or mires). The water content of buried peat is less than that of recent peat. Processing decreases the moisture capacity of fuel peat. These traits/properties mean that different plants, fruits, vegetables, and other things are going to be more suitable for growing in peat soil than others. Peat is generally distinguished from soil by its high content of organic compounds —at least 50 percent of the weight after all moisture is removed. Peat is mechanically processed by various working elements: augers, augers and blades, spiral cones, cones, slits, and crushing and grinding devices. There are 51 million ha in Western Europe, more than 100 million ha in Asia, and more than 18 million ha in North America. Peat definition, a highly organic material found in marshy or damp regions, composed of partially decayed vegetable matter: it is cut and dried for use as fuel. of, pertaining to, resembling, or containing the substance peat. Weakly decomposed peat is an excellent filtering material; highly dispersed peat is used as an antifiltration material. Peat soil has traits/properties that make it different from other types of soils. Classification. Peat is formed from the residues of dead plants whose aerial organs have become humified and mineralized in the aerated surface stratum of a bog (the peat-producing horizon) by soil invertebrates, bacteria, and fungi. By resisting compaction, it ventilates oxygen deep into the soil … The dispersion of raw peat increases the rate of shrinkage, a prerequisite for obtaining a compact and strong product. The latter extract the peat mass from a layer by means of milling devices that process and spread a layer of peat on the surface of the field. In the view of some scientists, peat is a precursor of a genetic series of coals. Peat soils are the upper portion of peat bog deposits, formed below a layer of particular types of vegetation that thrive under conditions of excess moisture. The possibility of using peat from a single deposit simultaneously for agricultural and industrial purposes fostered a new trend in peat utilization—the combination use of peat—made possible by the varied properties of the different species types of peat. | Meaning, pronunciation, translations and examples The most effective way to store peat and prevent spontaneous combustion is to insulate the piles from the air with a layer of wet peat. : a blackish or dark brown material that is the remains of plants partly decayed in water and is dug and dried for use as fuel. Humus imparts a dark color to peat. Kats, M. I. Neishtadt, N. I. P’iavchenko, V. E. Ra-kovskii, V. N. Sukachev, and S. N. Tiuremnov. In the 19th century peat was studied by V. V. Dokuchaev, S. G. Navashin, and G.I. Peat can be added to soil to help plants grow, or can be burned to produce coal. Formation of peat. The formation of peat acts as a carbon sink, removing carbon dioxide from the atmosphere, but that carbon dioxide is released when peatlands dry out naturally or are drained, and when peat is burned. I. CHISTIAKOV. peaty Lentils are grown on a wide variety of soils from sandy loam to deep peaty soils. Thorough prospecting is done in order to obtain data for plans for the exploitation and utilization of a peat deposit. Peat typically has a high moisture content in the natural state (88–96 percent), high porosity (up to 96–97 percent), and high compressibility. Scotland’s National Peatland Plan also encompasses organic soil less than 50cm, which can support typical peatland vegetation (SNH, 2015a). The underground organs in an anaerobic medium are preserved, and they form the structural, or fibrous, part of peat. Twenty-five primary types of peat bogs are distinguished in the European USSR and 32 in Western Siberia. "As a lowland raised bog, Cors Fochno is a stronghold for this species because of its abundant supply of food and its waterlogged, Habitat: A small, herbaceous perannial member of the Droseraceae family growing up to 10cm in, Among the topics are engineering properties of, MERCuRY Bahira Sun Tzu King Of Castile Breaking Silence Osmosia Suburban Bay Dj Milan 7.50 'NATIONAL HuNT' (CLASS 5) Carving out a living and raising a large family on a windswept upland farm with poor, It seems to work quite well at Wincanton, where there is predominantly a good soil with a clay base, whereas Exeter is more a, Dictionary, Encyclopedia and Thesaurus - The Free Dictionary, the webmaster's page for free fun content, Agricultural Micronutrients Market Dynamics, Segments and Supply Demand 2018 2027, Campers warned against dangers of peaty soil fires; Nature: Blazes can break out even after people leave, Rosy future for rare moth that hitched train ride, Some Blaine residents want Hy-Vee, others fear traffic, Plant of the week: Juice of insect eating plant was used to fight ageing, The green miles; Forget Route 66. These subtypes differ in degree of decomposition. Exploitation of peat deposits. Peat has a lot of important qualities which determine its worth for agriculture: 1. The three types of peat—high-moor, transitional, and low-moor—are classified according to the composition of the original plant material, conditions under which the peat was formed, and the peat’s physical and chemical properties. The piles are then loaded onto tractor-drawn dump trucks and transported to intermediate railroad warehouses. Complex use of peat. Silty Soil.

Loss of volume (%) of peat soils from drained fen locations. In the 12th and 13th centuries peat was known as a fuel in Holland and Scotland. In this method the peat is dug from narrow trenches, processed, and pressed into bricks. Peat is extracted in the USSR by milling (more than 95 percent of the total commercial extraction), excavation, and the deep-pit method. This is the most qualitative peaty fuel which is used at boiler houses and by population. ‘Deep peat ’ is considered to be a peat soil with a surface organic layer greater than 1.0 0m thickness (Bruneau and Johnson, 2014).
