Antarctic soil microbiomes encode structurally conserved and phylogenetically diverse beta‐lactamases

iMetaOmics, Volume 3, Issue 3, September 2026.
An integrative metagenomic framework combining sequence, structural, and functional inference reveals a phylogenetically diverse and structurally conserved repertoire of putative beta‐lactamases across Antarctic soil microbiomes, with predominance of class A and subclass B3 enzymes and limited but detectable associations with mobile genetic elements ...

Long‐Term Straw Returning Combined With Mineral Fertilization Enhances Soil Quality but Elevates P Loss Risks in a Subtropical Rice–Wheat Rotation System, Central China

Land Degradation &Development, Volume 37, Issue 15, Page 10732-10745, September 2026.
ABSTRACT Long‐term straw returning is widely promoted to improve soil quality in intensive cropping systems, yet its combined effects with mineral fertilization on soil quality and phosphorus (P) loss risks remain unclear. Using a 16‐year field experiment in a rice–wheat rotation system, we evaluated the impacts of straw returning (S), NPK ...

Short-Term Impacts on Soil Biological Properties After Amendment with Biochar from Residual Forestry Biomass

Agriculture
The increasing challenges posed by climate change demand efficient strategies to mitigate soil degradation. Valorization of low-grade residual forestry biomass (acacia) into biochar could be used as a soil amendment strategy.

Synergistic Chemodynamic–Photothermal Antibacterial Activity of a Nanozyme Derived From Processed Pyritum

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Pyritum can eliminate blood stasis and promote the healing of muscles and bones, which has been used as a traditional mineral medicine in China for thousands of years. However, the mechanisms of action and processing methods of Pyritum were not illustrated.

Automated Daily Measurements of Soil Pore Space CO2 and O2: Signals Revealing Soil Physical and Biogeochemical Processes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract There is a need to understand and monitor active soil processes in the field; however, it is challenging to observe and separate co‐occurring belowground processes. High precision monitoring of soil pore space gases is a potentially powerful approach, complicated by the variety of biological and physical processes that impact gas.

IMPACTS OF REPLACING THE AMAZON RAINFOREST WITH PASTURE ON SOIL PROPERTIES

Revista de Agricultura Neotropical
The conversion of the Amazon rainforest into pasture significantly impacts soil quality, affecting biodiversity, biogeochemical cycles, and carbon stocks. Studies indicate a reduction in microbial activity and biomass associated with this transformation.
