Compost, peat, and sludge are used in agriculture and gardening as soil amendments rather than as fertilizers, because they have a low content of plant nutrients. Pine-apples are sometimes grown without pots, in peat soil, through which pipes of hot water are carried so as to heat the earth to 95°, while the atmosphere is kept moist, and decayed leaves are laid on the surface and drawn up round the plants. A relocation of state highway No. Peat is an organic complex soil, well known for its high compressibility and low stability. Applications for felling licenses on peat soils must also be treated differently. Heavy rates of application are common. Abstract. Peat is formed in wet areas when plant matter is inhibited from fully decaying by acidic or anaerobic means. Therefore, Dykes and Warburton (2007a) recommended that the lower limit of 0.4 m for defining a peat deposit should be used for the definition of a peat failure so as to reflect the environmental importance of peat loss and thus to minimize the possible exclusion of failures involving very thin peat/organic soil. Peat Soil organic soils containing more than 20% organic matter in various degrees and states of decomposition. Information and translations of PEAT in the most comprehensive dictionary definitions resource on … Peat (/ p iː t /), sometimes known as turf (/ t ɜːr f /), is an accumulation of partially decayed vegetation or organic matter.It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. ‘a peat bog’ ‘Potting soil contains rich organic material such as peat and various composted barks.’ ‘The route meanders up, over the rocks and then more peat bog.’ ‘Dig materials such as straw, peat, compost, and leaves into the soil, or lay them on as mulch.’ Compost, or synthetic manure, is basically a mass of rotted organic matter made from … Peat definition is - turf. Peat Defined. What does PEAT mean? To test if the limits considered in the definition of peat were an important source of uncertainty, simulations were run changing the limits of depth (by 5 cm) and organic matter contents (by 5%). This restricted definition, including only materials which are entirely of vegetative origin, conflicts with several established soil classification systems. This paper considers three topical problems—the definition of peat soils as natural-historical formations and the estimation of their profile thickness, the analysis of the genesis of organic soils, and the principles of the classification of peat soils. The Lady's Country Companion: or, … Simulations for soil peat definition. Peat moss is considered a natural soil amendment or soil replacement. It became widespread among gardeners back in the mid-1900s. This peat is more a super-rich loam soil than pure organic matter.

You can use peat in gardens and potted plants, to help the soil stay moist. Peat is a rich, dark, dirt-like material that's made from decomposed organic matter. The generic RSPO definition of peat soil is as follows: “Histosols (organic soils) are soils with cumulative organic layer(s) comprising more than half of the upper 80cm or 100cm of the soil surface containing 35% or more of organic matter (35% or more Loss on Ignition) or 18% or more organic carbon” In Malaysia, Histosols are subdivided into muck and peat soil. Tropical peatland ecosystems consider as a key roles not only in the storage of carbon in forests and peat, but also in controlling water resources and in preserving bio-resources and biodiversity. Oxygen flow from the atmosphere is obstructed by flooding in the wet areas where peat is found in the soil and this helps to prevent or slow decomposition. Meaning of PEAT. / A pretty peat! The soil was classified as peat soil according to its soil characteristics. The proportion of locations shifting classification from/to peat … The humidity and the saturated soil water content in Sphagnum peat are the highest, and they are least in herbaceous-woody peat. The definition of ‘Histosol’ (FAO 1998, 2006/7; USDA 2014) above will be used for regions without its own specific definition. They may be incorporated into the soil or mulched on the surface.

Peat is traditionally defined as being synonymous with turf being partially carbonized vegetable tissue formed in wet conditions by decomposition of various plants and mosses.
