Germanium-silicon fractionation in a tropical, granitic weathering environment
63
TL;DR: Germanium-silicon (Ge/Si) ratios were determined on quartz diorite bedrock, saprolite, soil, primary and secondary minerals, phytolith, soil and pore waters, and spring water and stream waters.

Tracing the origin of dissolved silicon transferred from various soil-plant systems towards rivers: a review
TL;DR: In this paper, the authors identify relevant geochemical tracers of Si pathways within the soil-plant system to obtain a better understanding of the origin of DSi exported towards rivers.
Plant impact on the coupled terrestrial biogeochemical cycles of silicon and carbon: Implications for biogeochemical carbon sequestration
TL;DR: The coupled terrestrial biogeochemical cycles of silicon (Si) and carbon (C) that are driven by plant action play a crucial role in the regulation of atmospheric CO2 as discussed by the authors, suggesting that complex feedbacks exist within the processes within the coupled Si and C cycles.

Jean-Thomas Cornélis,Bruno Delvaux,Damien Cardinal,Luc André,Jacques Ranger,Sophie Opfergelt +5 more
TL;DR: In this paper, the authors trace the source of dissolved Si in forest floor leachates and in soil solutions under various tree species at homogeneous soil and climate conditions, using stable Si isotopes and Ge/Si ratios.

Heather L. Buss,Maria Chapela Lara,Oliver W. Moore,Andrew C. Kurtz,Marjorie S. Schulz,Art F. White +5 more
TL;DR: In this paper, the authors compared two nearby catchments in the Luquillo Critical Zone Observatory in Puerto Rico, which have similar climate history, relief and vegetation, but differ in bedrock lithology.

Revised effective ionic radii and systematic studies of interatomic distances in halides and chalcogenides
TL;DR: The effective ionic radii of Shannon & Prewitt [Acta Cryst. (1969), B25, 925-945] are revised to include more unusual oxidation states and coordinations as mentioned in this paper.

Global silicate weathering and CO2 consumption rates deduced from the chemistry of large rivers
TL;DR: In this article, newly compiled data on the 60 largest rivers of the world are used to calculate the contribution of main lithologies, rain and atmosphere to river dissolved loads, and the relationship between the chemical weathering rates of silicates and the possible controlling parameters are explored.

Standard soil methods for long-term ecological research

- 01 Jan 1999
TL;DR: In this paper, site and landscape characterisation for ecology studies is presented. But the authors focus on the soil properties rather than the environment, focusing on the characteristics of the soil.
