“…Hence, the plant structure in Image B can be seen with some degradation, as H5 was categorized as moderately decomposed peat (hemic). H3 was the lowest degree of humification in this site and similar to the study in [28]. As the plant structure is easily identifiable [6], the plant structure can be seen (Image C) with some degradation showing that peat was very slightly decomposed [22].…”

In Malaysia, peat soils have been successfully planted with various crops such as pineapple, oil palm, and sago. However, the development of peat soils to plantations may raise problems to the environment and alter their physical and morphological characteristics. Hence, this study was conducted to differentiate peat soils microstructure between natural peat and pineapple cultivated peat. The soil samples were taken at 0-50 cm, 50-100 cm, and 100-150 cm depth, and the Von post scale method was conducted in the field. The samples were tested in the water content, organic content, and rubbed fiber content for physical analysis. The samples were then sent to the scanning electron microscope (SEM) and energy dispersive x-ray (EDX) analysis to determine peat soil microstructure and elemental analysis. The results showed that the pineapple cultivated peat has a higher humification degree than natural peat. The fast degradation process of cell walls also can be seen in SEM images in higher humification degrees. It is concluded that the disturbance of peatlands due to human activities may accelerate the decomposition process in peat soils.

“…Based on this scale, peat soils are classified as H 4. [17] state that compotition of soil organic matter in peat soil was not related with the degree of humification. The results of classification of peat soil from Dusun III Banyu Urip (Table 4) The results of chemical characteristics of peat soil based on Table 3 described that the organic content (OC, %) =77.40-80.99, the fiber content (FC, %) = 70.45-76.66, and the ash content (AC, %) = 19.01-22.31.…”

“…The samples were powdered and dried in a drying chamber at 105°C. KBr-pellet samples were prepared using the following technique (Thermo Electron Corporation, 2006) with some additions proposed by Broder et al (2012), Krumins et al (2012), and Teong et al (2016). KBr powder with purity appropriate for FT-IR-analyses was placed in a glass sample cup and stored in a drying chamber at 105°C during the process.…”

We present the results of multiproxy study of a peat deposit from Carlisle Island (the Islands of Four Mountains, Aleutians). Vegetation on the initial stage of the peat is characterized by heath vegetation dominated by Ericales indicating cold conditions at 7300–6100 cal yr BP. The appearance of Betula and Alnus is the result of long-distance transportation attributable to strong winds at this time. Sedge-grass (Cyperaceae and Poaceae) communities began replacing heath vegetation at 6100 cal yr BP because of the climatic amelioration. C/N ratios and pollen spectra remain relatively stable at 6100–2450 cal yr BP. For the CR-03 peatland, volcanic tephra contributed significantly to the Fourier transform infrared spectroscopy spectral data. Volcanic input created overlap of an aluminosilicate signal with carbohydrate vibrations. Significant changes occurred at approximately 2450 cal yr BP when there is the some evidence of cooler and wetter conditions of the Neoglacial. High values of δ15N observed at 7100–7000 cal yr BP reflect the fertilizing effect of seabird nesting colonies. A decrease in δ15N ca. 6900 cal yr BP may indicate initial settlement on Carlisle Island corresponding with harvesting seabirds. Human predation continued until a series of volcanic eruptions, which deposited Okmok II and CR-02 tephra layers at ca. 2000 and 1050 cal yr BP, respectively.
