Mapping Annual Crop Residue Cover Across Global Mollisol Regions at 10-m Resolution (2019–2024)

. Mollisol regions are among the world’s major grain-producing areas, yet intensive cultivation and residue removal threaten the long-term sustainability of these fertile soils.

Soil Aggregate Response to Three Freeze-Thaw Methods in a Northeastern China Mollisol [PDF]

, 2019
Freeze-thaw (FT) cycles occur annually in soils of mesic and frigid temperature regimes. FT has profound impacts on soil aggregates yet is often difficult to document in field settings. As a result, laboratory-based FT experiments are widely used, albeit

Understanding cation exchange capacity through the landscape lens of the Busoga Catena, Uganda

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract This study identifies the parent material (PM) and examines cation exchange capacity (CEC) across the Busoga catena. In 2022 and 2023, we described 32 pedons and collected 147 samples. Laboratory analyses were particle size analysis, organic carbon (OC) content, pH, and CEC.

Soil Erosion Characteristics and Mechanisms Affecting Maize Yield on Sloping Farmland in the Chinese Mollisol Region

: Soil erosion poses a severe threat to food security on sloping farmland in the Mollisol region of Northeast China, primarily through the loss of nutrients, especially soil organic carbon (SOC).

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.

Accumulation of Labile P Forms and Promotion of Microbial Community Diversity in Mollisol with Long-Term Manure Fertilization

, 2023
Soil phosphorus (P) can be divided into inorganic P (Pi) and organic P (Po). Microorganisms play essential roles in soil P transformation. However, there are many ways to detect P transformation, and the relationship between P forms and microorganisms ...

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

Soil respiration induces co-emission of greenhouse gases and methylated selenium from cold-region Mollisols: Significance for selenium deficiency

Environment International
Mollisols rich in natural organic matter are a significant sink of carbon (C) and selenium (Se). Climate warming and agricultural expansion to the cold Mollisol regions may enhance soil respiration and biogeochemical cycles, posing a growing risk of soil

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 ...
