Abstract:

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).

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.

This layer has various thicknesses at different locations ranging between R.L. . 10 to R.L. -19.6 m.

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

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. Peat profile observations were made using a peat drill (Eijkelkamp, Giesbeek, Netherlands) by taking 50 cm and 5.2 cm peat cores in Meskom Village, Bengk

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.

Peat pore surface wettability, which is determined by pore surface chemistry, has strong hysteresis and shows hydrophilic and hydrophobic behaviors during water drainage from and water imbibition into pore spaces. This leads to high residual NAPL saturation in pore spaces. Systematic reduction of
