The results of this paper describe the characteristics of peat soil from physical and chemical testing. Deriving the distribution of the pore size from the water retention curve was flawed because of shrinkage due to drainage, especially at high soil water potentials. Peat soil are characterized by high compressibility parameters and low initial shear strength. Peat or highly organic soil is a major problem in infrastructure development of the tropical and coastal regions. According to the statistics inBasic Characteristics and Measuring Methods of Peat, the decomposition degree of oligotrophic peat (15 to 25%) is usually lower than that of eutrophic peat (25 to 35%). Soil physical characteristics of peat soils 483 drainage and wetting of the strongly earthified surface layer (15 to 25 cm depth, strongly earthified horizon) are more Select data courtesy of the U.S. National Library of Medicine. Search Hence, characterization and improvement of peat is necessary to construct any type of infrastructure on it. the soft or peat soil stabilization and their physical and engineering properties [2,7,12-18].

KEY WORDS: air volume content, water retention, wettability. Other significant properties of peat soil its organic content, fibre content, specific gravity, bulk density and pH which were 96.45%, 90.39%, 1.24, 1037.73 kg m -3 and 3.51, respectively. These errors became greater as the peat was less influenced by soil‐genetic processes. Hence decomposition and humification result in the degradation of the soil structure and a reduction in the soil capacity to store, retain and transmit water. Peat soil: Organic soils, which have slightly decayed or non-decayed plant materials are called peat soils. Peat has typical characteristics, which include high natural moisture content, high compressibility and water-holding capacity, low specific gravity, low bearing capacity, and medium-to-low permeability [ 3 ].

Deriving the distribution of the pore size from the water retention curve was flawed because of shrinkage due to drainage, especially at high soil water potentials. Pristine peat soils are characterized by large porosity, low density and large water and organic matter contents. Peat, in its natural state, contains excessive amount of water due to its low physiography and water holding capacity of 20 to 30 times its own weight. A Note On Soil Types, & What Ultimately Impacts How Things Grow. Soil Organic Matter content (SOM) was determined by loss-on-ignition (ISO 22476-3:2005) and expressed as mass of OM per unit volume of soil. peat soil characteristics. In this connection Driessen (1977) is worth quoting: “A normal peat soil with bulk density of 0.1 g/cm 3 and a nitrogen content of 2 percent contains only 2 000 kg N/ha in its upper 10 cm (assumed wood-free), whereas a mineral surface horizon with only 0.5 percent N but a bulk density of 1 g/cm 3 contains 5 000 kg/ha. Peat soils are coarse textured or fine- textured depending on the nature of deposited plant residues. This chapter describes some of the chemical and physical characteristics of the Everglades peatlands including the distribution of organic C and nutrients (N, P), historical and recent rates of peat accretion, nutrient accumulation, and the effects of anthropogenic hydrologic alteration and nutrient enrichment on these processes. Abstract. Get unlimited, online access to over 18 million full-text articles from more than 15,000 scientific journals. Sand particles are the largest and clay particles the smallest. Peat is formed primarily from decaying organic substrates and the biomass of decomposer the communities consuming them. The problems with deep peat lie in its physical and chemical characteristics. Soil Texture. Peat soils are highly complex porous media with distinct characteristic physical and hydraulic properties. The reason of comparing these two different types of soil was to obtain the Liquid limit is found to be more than 50 % hence, the soil is classified as highly compressible organic soil (OH). Soil mineral particles are derived from the weathering of rocks and minerals. Thanks for helping us catch any problems with articles on DeepDyve.

The characteristic of microbial composition of the peat production is a well-documented difficulty for incessant large-scale processing. Pore sizes in undecomposed peat can exceed 5 mm, but significant shrinkage occurs during dewatering, compression and decomposition, reducing pore-sizes. Banyuasin is one of the regency in South Sumatera which has an area of 200.000 Ha of peat land. Several soil scientists have shown that the capacity of soil to exchange cations is the best index of soil fertility. https://doi.org/10.1016/j.geoderma.2009.08.018. The water retention curves (desorption) evaluated in the field and the laboratory satisfactorily corresponded. Agrophysics, 2002, 16, 161-165 Water retention characteristics of peat and sand mixtures The physical properties of peat soil consists of organic content, particle size distribution, specific gravity and Atterberg limits The physical and chemical characteristics of peat include water content (ω), specific gravity (Gs), Acidity (pH), unit weight (γ), and ignition loss tests. The drainage of low-lying peatland for agriculture and subsequent conservation measures adopted on some of these peatlands has led to differing degrees of change in the physical and hydraulic characteristics of the soil. physical, chemical and morphological properties of the Yenicaga, Bolu peatland displaying typical characteristics of Turkish basin peat soils and classify it according to Soil Taxonomy (1999) with regard to formation. The physical and hydraulic properties of the peats considered were significantly influenced by the degree of decomposition.

Bog peats have low nutrients with usually 35-50% carbon content, whereas swamp peats have higher mineral content – 15-40% carbon. 15,000 peer-reviewed journals. The physical properties of peat soil consists of organic content, particle size distribution, specific gravity and Atterberg limits were evaluated as given in Table I. in peat soil based on physical modelling, analyse using physical model the stress distribution beneath the structure in peat soil and to compare the peat behaviour with sand. The predominance of desirable ions in the exchange complex brings about good physical cations and favorably influences the microbial activities in the soil, such as ammonification nitrification, etc. We assessed the degree of peat decomposition and measured the soil organic matter (SOM) content, particle density, dry bulk density, saturated hydraulic conductivity, and water retention and shrinkage characteristics for a range of peat soil horizons sampled in two low-lying agricultural peatland in England. Drainage and intensive use of fens lead to alterations in the physical characteristics of peat soils. In addition, they had a higher saturated hydraulic conductivity. There are different types of peat soils, such as bog peat and swamp peat. Few researchers have discussed the physico-chemical and morphological characteristics of organic soil and peat soils [19-23]. Consequently, aeration is poor and bulk density is very low at less than 0.1 g cm-3. The drainage of low-lying peatland for agriculture and subsequent conservation measures adopted on some of these peatlands has led to differing degrees of change in the physical and hydraulic characteristics of the soil.
