Incipient ferralization and weathering indices along a soil chronosequence in Taiwan [PDF]

, 2016
The low hilly topography of Green Island, a volcanic island off southeastern Taiwan, includes an altitudinal sequence of sub-horizontal benches. We examined eight profiles along this sequence, ranging from pale brown loamy coral sand on the lowest bench ...

Structural composition of organic matter in particle-size fractions of soils along a climo-biosequence in the main range of Peninsular Malaysia

Open Geosciences, 2016
Information on structural composition of organic matter (OM) in particle-size fractions of soils along a climo-biosequence is sparse. The objective of this study was to examine structural composition and morphological characteristics of OM in particle ...

Organic carbon and microbiome in tundra and forest–tundra permafrost soils, southern Yamal, Russia

Polar Research, 2021
Permafrost soils differ significantly from other soils because they serve as a huge reservoir for organic carbon accumulated during the Quaternary Period, which is at risk of being released as the Arctic warms.

A micromorphological evaluation of pedogenesis on Isla Santa Cruz (Galápagos) [PDF]

, 2013
Thin sections of about 200 horizons or layers, representing 60 soil profiles in the coastal area and on the windward slopes of Isla Santa Cruz (Galápagos Islands) were analysed.
