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.

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.

Comparative study of the mycorrhizal root transcriptomes of wild and cultivated rice in response to the pathogen Magnaporthe oryzae

Rice, 2019
Background Rice, which serves as a staple food for more than half of the world’s population, is very susceptible to the pathogenic fungus, Magnaporthe oryzae. However, common wild rice (Oryza rufipogon), which is the ancestor of Asian cultivated rice (O.

Soil macroaggregates and organic-matter content regulate microbial communities and enzymatic activity in a Chinese Mollisol

Journal of Integrative Agriculture, 2019
The formation and turnover of macroaggregates are critical processes influencing the dynamics and stabilization of soil organic carbon (SOC). Soil aggregate size distribution is directly related to the makeup and activity of microbial communities.

Removal of Crop Ion Components in Relation to Mollisol Acidification under Long-Term Management

Agronomy
Crop removal of cations and anions is one of the main factors causing soil acidification. Mollisols, also known as black soils, which are inherently neutral soils, have been acidified due to irrational land use. However, the magnitude of acidification of

The Lower Boundary of Selected Mollisols [PDF]

, 1967
Thicknesses of three Mollisols (Tama, Elburn, and Drummer series), developed from Wisconsinan-age material in a toposequence in Central Illinois, were considerably greater (18 to 68 cm) when their lower boundaries were determined by the depth of rooting ...
