Spatial and vertical distribution of redox‐sensitive elements and their controlling factors in deep soils under contrasting land cover in the Gulf Coastal Plains

Vadose Zone Journal, Volume 25, Issue 4, July/August 2026.
Abstract Redox processes in soil governs key biogeochemical cycles and influence carbon, nitrogen, and phosphorus dynamics. However, their role in deep vadose zone soils remains poorly understood, particularly in variably saturated environments with heterogeneous hydroclimatic, landscape position, and land use conditions.

The Microbial Functional Communities of Mollisol and Saline–Sodic Paddy Soils at Rice Heading and Harvest Stages in Northeast China

Agriculture
Rice is a primary food source for nearly half of the global population. In Northeast China, paddy soils are mainly classified into two distinct types: fertile mollisol and nutrient-deficient saline–sodic soil.

Elevated moisture stimulates carbon loss from mineral soils by releasing protected organic matter

Nature Communications, 2017
The effect of soil moisture on microbial activity and soil carbon storage remains unclear. Here, via Mollisol incubation experiments, the authors show elevated soil moisture can accelerate total carbon loss by facilitating microbial access to previously ...

Variable Source Zones Controlling Flow, Water Age, and Nitrate Export Dynamics in a Tile‐Drained Lowland Watershed

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Linking hydrograph dynamics with transport velocities and biogeochemical responses remains a central challenge in watershed hydrology, yet it is critical for understanding nitrogen reactive transport and its implications for water quality. In this study, we combined high‐frequency measurements of stable water isotopes and nitrate concentration

Plant functional groups and root traits are linked to exudation rates of mature temperate trees

Functional Ecology, Volume 40, Issue 7, Page 2203-2220, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudation affects soil biogeochemistry profoundly, yet it is rarely quantified in mature, field‐grown trees and its controls are poorly understood. We measured rates of carbon (C) exudation in 11 tree species that exhibit divergent root traits, including ...

Extraction Kinetics and Molecular Size Fractionation of Humic Substances From Two Brazilian Soils

Journal of the Brazilian Chemical Society, 1999
In the present study, the extraction behaviour of humic substances (HS) from an Oxisol and a Mollisol from South Brazil, by using 0.1 and 0.5 mol L-1 NaOH and 0.15 mol L-1 neutral pyrophosphate solutions, respectively, was systematically studied.

Linking Plant and Microbial Traits to Soil Carbon for Reliable and Resilient Bioenergy Systems

GCB Bioenergy, Volume 18, Issue 7, July 2026.
Plant–microbe–soil interactions supporting productivity and soil carbon storage in bioenergy systems. Plants supply organic inputs that sustain microbial communities driving nutrient cycling, carbon stabilization, and soil aggregation. These interactions enhance soil structure and nutrient retention, supporting both biomass productivity and broader ...

Short‐Term Effects of Contrasting Management Regimes on Plant Species Diversity, Herbage Production and Soil CO2 Emissions in Species‐Rich Grasslands

Grass and Forage Science, Volume 81, Issue 3, July-September 2026.
ABSTRACT Semi‐natural grasslands are among the most plant‐rich ecosystems worldwide, providing multiple ecosystem services but requiring site‐specific management for their conservation. This study assessed short‐term dynamics of plant biodiversity, herbage production, pastoral value and soil CO2 emissions under contrasting management regimes in ...
