Mineralogical associations with soil carbon in managed wetland soils

open access: yesGlobal Change Biology, 2020
AbstractCarbon (C)‐rich wetland soils are often drained for agriculture due to their capacity to support high net primary productivity. Increased drainage is expected this century to meet the agricultural demands of a growing population. Wetland drainage can result in large soil C losses and the concentration of residual soil minerals such as iron (Fe)

Direct Formation of Structural Components Using a Martian Soil Simulant. [PDF]

open access: yes, 2017
Martian habitats are ideally constructed using only locally available soils; extant attempts to process structural materials on Mars, however, generally require additives or calcination.

Influência de formas do relevo em atributos físicos de um latossolo sob cultivo de cana-de-açúcar Influence of the relief forms on physical attributes of an oxisol cropped with sugarcane

open access: yesCiência Rural, 2006
Os atributos físicos do solo variam em função das formas do relevo e sofrem influência da mineralogia da fração argila e do manejo da cultura de cana-de-açúcar, podendo interferir no processo de compactação do solo.

Visible and Near-Infrared Reflectance Spectroscopy for Investigating Soil Mineralogy: A Review

open access: yesJournal of Spectroscopy, 2018
Clay minerals are the most reactive and important inorganic components in soils, but soil mineralogy classifies as a minor topic in soil sciences. Revisiting soil mineralogy has been gradually required.

Chemical dispersants and pre-treatments to determine clay in soils with different mineralogy

open access: yesRevista Brasileira de Ciência do Solo, 2011
Knowledge of the soil physical properties, including the clay content, is of utmost importance for agriculture. The behavior of apparently similar soils can differ in intrinsic characteristics determined by different formation processes and nature of the

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

open access: yesArchaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...

Application of a novel method for soil aggregate stability measurement by laser granulometry with sonication [PDF]

open access: yes, 2013
Aggregate stability is an important physical indicator of soil quality, and so methods are required to measure it rapidly and cost-effectively so that sufficient data can be collected to detect change with adequate statistical power. The standard methods

Forest soils accumulate microplastics through atmospheric deposition

open access: yesCommunications Earth & Environment
The occurrence and fate of microplastics in forest ecosystems is a recognized knowledge gap. In this paper, we used an aligned extraction method to quantify microplastics (>20 µm) in organic and mineral forest soil horizons and throughfall deposition ...

Microbial Community Dynamics in Soil Depth Profiles Over 120,000 Years of Ecosystem Development

open access: yesFrontiers in Microbiology, 2017
Along a long-term ecosystem development gradient, soil nutrient contents and mineralogical properties change, therefore probably altering soil microbial communities.
