Effect of soil health management on soil water storage for climate resilience

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Soil health (SH) management has been promoted to improve climate resilience across agricultural systems. An on‐farm field study was conducted to (1) evaluate the soil water storage (SWS) in SH and conventional (CV) management systems across four paired sites in Minnesota and Wisconsin and (2) to assess the response of these management systems ...

Soil, competition, and niche shifts shape the floral mosaic of an annual plant diversity hotspot

American Journal of Botany, Volume 113, Issue 3, March 2026.
Abstract Premise Plant species with affinity for harsh substrates often have well‐defined edaphic (soil) niches and are ideal for exploring questions of community assembly. Vertic clay soils are chemically and physically challenging to plant establishment and productivity, and annual plant communities associated with these soils of the San Joaquin ...

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.

Responses of ammonia-oxidizing bacterial communities to land-use and seasonal changes in Mollisols of Northeast China

, 2016
In this study, AOB community was investigated over a 2-year period in cultivated Mollisols (0-20 cm) with three fertilizer treatments [no fertilizer (NoF), chemical fertilizer (CF) and chemical fertilizer plus manure (CFM)] and in an adjacent plot under ...

Crop Residue Return Rather Than Organic Manure Increases Soil Aggregate Stability under Corn–Soybean Rotation in Surface Mollisols

, 2022
Fertilization practices change soil organic carbon content and distribution, which is relevant to crop rotation and soil aggregates. However, how fertilization management under corn–soybean rotation affects soil organic carbon and aggregate stability at ...

Interactions Between Dissolved Organic Carbon and Aluminium Activity in Tropical and Temperate No‐Till Agroecosystems

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
Conceptual model of depth‐stratified soil acidification under long‐term no‐till in temperate (Washington, USA) and tropical (Brazilian Oxisol) systems. Nitrogen inputs promote surface acidification (↓pH) and increased Al3+ activity, while lime or silicate amendments modify base cation dynamics. Increased DOC–Al complexation reduces free Al3+ and alters

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

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.
