ABSTRACT Soil microbial communities provide numerous ecosystem functions, such as nutrient cycling, decomposition, and carbon storage. However, global change, including land‐use climate changes, affects soil activity. As extreme weather events (e.g., heatwaves) tend to increase in magnitude frequency, we investigated the effects of heat stress on activity respiration) that had experienced four different long‐term intensity treatments (ranging from extensive grassland intensive organic conventional croplands) two conditions (ambient vs. predicted future climate). We hypothesized both land use would reduce respiration (H1) experimental (H2). this be less pronounced soils with a history high‐intensity (H3), higher fungal‐to‐bacterial ratio show more moderate response warming (H4). Our study showed was reduced under high (i.e., −43% between cropland) (−12% comparison ambient Moreover, increased overall (+17% per 1°C increase), while increasing strength (−25% slope reduction). In addition, biomass low‐intensity grassland) enhanced stress. These findings change may compromise well their heatwaves. particular, are able respond additional stress, heatwaves, potentially threatening critical functions driven by microbes highlighting benefits sustainable agricultural practices.

Soil health is a critical determinant of agricultural productivity and environmental sustainability. Traditional assessment methods often fail to provide comprehensive understanding soil microbial communities their functions. This study addresses this challenge by employing metagenomic techniques assess the functionality microbiomes in Russian black soil, renowned for its high fertility. We utilized shotgun sequencing analyze samples from Western Siberia subjected different degrees agro-soil disturbance. identified functional genes involved carbon (accA, argG, acsA, mphE, miaB), phosphorus (phoB, ppa, pstB, pnp, phnJ), nitrogen (queC, amiF, pyrG, guaA, guaB, napA) metabolic pathways associated with changes diversity, general, higher representation certain bacterial species—Bradyrhizobium spp. The results demonstrated significant differences composition potential between tillage treatments. No-Till technology conventional practices promoted beneficial enhanced compared long-term fallow soil. work underscores analysis providing health, marking advancement field.
