Spodosol development and soil organic carbon distribution along a lithosequence in perhumid coastal temperate rainforest

Soil Science Society of America Journal, Volume 88, Issue 5, Page 1509-1528, September/October 2024.
Abstract A dense concentration of old‐growth forest and a wet, cold climate promote mineral weathering and leaching in coastal temperate rainforest soils. Our objective was to assess soil development and soil organic carbon (SOC) distribution across 18 soil profiles in remote, upland terrain of southeast Alaska where pedon data are sparse. We made soil

Assessing decadal soil redistribution rates using 239+240Pu across diverse lithologies in Southeast Alaska

Soil Science Society of America Journal, Volume 88, Issue 5, Page 1659-1677, September/October 2024.
Abstract Quantifying soil redistribution rates, including both erosion and deposition, is critical for understanding erosion processes, landscape evolution, land management strategies, and the carbon cycle. In the Northeast Pacific coastal temperate rainforest, the interaction of perhumid climate and dense coniferous forest tends to form Spodosols ...

The role of weathering and aeolian inputs on clay minerals and geochemistry in Podzols on ophiolitic materials

Geoderma
The process of podzolization in soils developed from ultramafic materials remains enigmatic, despite a few isolated cases described in subalpine areas under particularly acidifying vegetation and wet microclimatic conditions. The aim of this study was to

Characteristics of Clay Minerals in Podzols and Podzolic Soils [PDF]

Soil Science and Plant Nutrition, 2005
The clay minerals in Podzols and podzolic soils developed under coniferous forests in the Subarctic and Cool-temperate zones are characterized by the predominance of smectite and/or mica-smectite interstratified minerals in the eluvial horizons and chlorite-vermiculite intergrade in the illuvial horizons. A large amount of vermiculite is present in the

Plant strategy of root system architecture and exudates for acquiring soil nutrients

Ecological Research, Volume 39, Issue 5, Page 623-633, September 2024.
This paper synthesized plant strategies of root system architecture and organic acid exudation for acquiring soil nutrients in response to changes in nutrient availability (e.g., promoting mineral weathering, changing nutrient sources, and foraging nutrient hotspot in the soil profile). Abstract Vascular plants develop diverse root system architectures

Ecophysiological responses of native and introduced coastal tree species parasitized by Cassytha filiformis in Brunei

Plant-Environment Interactions, Volume 5, Issue 4, August 2024.
Our study aims to uncover the impacts of Cassytha filiformis on two native and two introduced hosts in terms of photosynthetic parameters, nutrient levels, and secondary bioactive compounds. Significant results were shown in certain nutrient contents, as well as total phenols and tannins in C. filiformis–host dynamics.

The Evolution of Hillslope Hydrology: Links Between Form, Function and the Underlying Control of Geology

Water Resources Research, Volume 60, Issue 3, March 2024.
Abstract Form and function are two major characteristics of hydrological systems. While form summarizes the structure of the system, function represents the hydrological response. Little is known about how these characteristics evolve and how form relates to function in young hydrological systems. We investigated how form and function evolve during the

SOILS WITH HIGH ORGANIC CARBON STORAGE CAPACITY IN DEPTH [PDF]

, 2012
Most studies about soil organic carbon (OC) stock focus on the topsoil storage capacity, however, it has been proved that OC can reach relatively high values also in depth.

Multivariate Analysis and Machine Learning in Properties of Ultisols (Argissolos) of Brazilian Amazon

Revista Brasileira de Ciência do Solo, 2018
: Ultisols are the most common soil order in the Brazilian Amazon. The Legal Amazon (LA) has an area of 5 × 106 km2, with few accessible areas, which restricts studies of soils at a detailed level.
