Zamrud National Park is the peak of the peat dome in the Kampar Peninsula. Peat depth data is needed as a baseline to maintain the balance of the water reservoir and carbon stock. Currently, available peat depth data is predictive photogrammetric data. Soil survey activities need to be carried out to provide accurate and up-to-date data. This research aims to map the peat depth using the best grid interpolation technique. Peat depth measurements were carried out terrestrially, while peat depth mapping used inverse distance weighted, kriging, and spline interpolation techniques. Drilling observ

AbstractOceanic mangroves accumulate peat with sea-level rise without terrestrial sediment inputs, but fossil peat’s elevation as a tide-range limited sea-level indicator is assumed to be affected by compaction. Despite assumption of decomposition, compression, and dewatering, pure Rhizophora mangle peat appears coarse, water-saturated, and loose even at depth. Calibrated peat densities from computed tomography (CT) and petrologic analysis allow quantitative assessment of compaction in continuous peats from Florida (6 m thick), Belize (12 m thick), and Panama (3.5 m thick).

It is found out that oxidation inhibitors of two types differing in reactivity and antioxidant content are present in peat lipids. In fuscum peats of the same type, the amount of AOs changes insignificantly with an increase in the depth of occurrence. A decrease in AOs of the second type is observed f

Peat is known for its importance as carbon storage. Peatlands in Malaysia especially forest reserve areas are generally lack of natural resources due to poor soil nutrients. Hence, many of peatlands in Malaysia have been converted to plantations and industrialized area.

Four woody nursery crops were propagated in 3 media in containers with 3 depths and 3 diameters. A container, 7.0 cm (2.8 in) depth and 5.6 cm (2.2 in) diameter provided the best plant performance both during propagation and production. Volume trend analysis suggests that depth and diameter, not just increasing volume, influence plant response. Performance during propagation was best in peat and perlite, followed by peat and vermiculite and 100% peat. However, subsequent plant growth during the growing season was best when the rooting medium was 100% peat.

In mangroves of South Florida, plant debris accumulates and humifies to form peat. The structure and composition of mangrove peat differs among mangal sub-habitats, leading to categorically distinct peat types reflective of the taphonomically active zone (TAZ). Here, taphonomic processes degrade and shape the peat until it is sequestered in the depth of final burial (DFB). Sequestered peats provide historical archives of the mangal depositional environment and the palaeoecological context of peat formation that are used to reconstruct mangal sub-habitats.

With the growing interest in peat as an energy fuel, the need for better inventories of this resource becomes increasingly important.

Abstract The subsoil conditions of Surfers Paradise in Southeast Queensland of Australia have been examined in terms of soil stiffness by using geographic information system (GIS). Peat is a highly organic and compressible material. Surfers Paradise (as a study area) has problematic peat layer due to its high water content, high compressibility, and low shear strength. This layer has various thicknesses at different locations ranging between R.L. . 10 to R.L. -19.6 m. Buildings in Surfers Paradise are using piled foundations to avoid the high compressibility and low shear strength peat layer.

The bulk samples (<250 μm and <100 μm) often yielded the youngest dates. The age difference between the individual fractions depended on the layer depth and hence the true age of the sampled peats.

Peat deposits accumulate large reserves of carbon and play an important role in formation of global climate, biosphere, and hydrological conditions. High degree of knowledge of peat reserves is one of the prerequisites for scientifically based and economically viable wetland management. For economically efficient commercial activity, an enterprise developing a peat deposit must be confident in the availability of sufficient and high quality commercial peat reserves. Therefore, the topic of studying the thickness of peat deposits is quite relevant. The paper analyzes the experience of using the

Determining peat depths can be done by intensive surveys which are expensive, inefficient, and ineffective, therefore, it is essential to find simple alternative methods for measuring peat depths. The research objective was to estimate and make maps of peat depths by applying Geostatistics analysis. This research was conducted on Muaro Jambi District, Jambi (Seponjen Village, Kumpeh) peatlands. The primary data was analyzed by ArcGIS 10.3 and Geostatistics programs. The spatial variability of peat depths on Site A (peat depth of 8.10–15.00 m) and Site B (3.10–8.00 m) showed maximum values at 2

This paper presents peat soil organic matter characteristics at Divcibare Mountain (950 m a.s.l, mountain climate). Excessive wetting is caused by groundwater and floods, and plant litter originates from hydrophilic vegetation. An investigation was aimed at determining the correlation between organic matter characteristics (humification degree, stability and bioavailability) with factors of soil formation and the most important physico-chemical characteristics of peat. Peat is mild acid and has a low base saturation. The content of organic matter is higher than 60% at depth of 40?80 cm, and hi

Abstract Humic substances form most of the organic component of soil, peat and natural waters, but their structure and properties are very much dependent on the source. The aim of this study was to characterize humic acids from raised bog peat to evaluate the homogeneity of humic acids isolated from the bog bodies and to study peat humification impact on the properties of humic acids. Peat humic acids (HA) have an intermediate position between the living organic matter and coal organic matter, with their structure formed in a process where the relatively labile moieties (carbohydrates, amino a

Peatlands have unique characteristics that are largely determined by the peat thickness. Ombrogenous peat has a high carbon content and low ash content, but not many studies have reported that this relationship also occurs in deep peat domes. This study aims to identify the C-organic content and ash content and determine the pattern of their relationship with peat thickness vertically from the peat surface to the mineral layer below the peat.

In Ukraine, more than 2,500 peat deposits with an average depth of 1.4 m have been identified. Of these, about 81% of producing peat is used as fuel, and 19% is for agricultural purposes.
