Alternate wetting and drying (AWD) frequently triggers nitrous oxide (N2O) emissions from paddy fields, while the inhibitory effect of 3,4-dimethylpyrazole phosphate (DMPP) on N2O under various water managements remains uncertain. Here, we evaluated effects DMPP associated biological indicators three managements: continuous flooding (CF), mild AWD (Mi-AWD), moderate (Mo-AWD). The Mi-AWD Mo-AWD practices increased by 2- 0.9-fold compared to CF treatment, respectively, due enhanced oxygen availability, facilitating coupled nitrification-denitrification. application notably reduced in treatments, attributed reductions nitrifier abundances, nitrification rates, nitrate accumulation. Nevertheless, failed suppress and, thereby, treatment. Overall, effectively mitigates oxygen-rich rather than anaerobic conditions, highlighting that trade-offs between water-saving irrigation mitigation can be overcome via inhibitors application.

Abstract Soil organic carbon (SOC) plays an essential role in mediating community structure and metabolic activities of belowground biota. Unraveling the evolution communities their feedback mechanisms on SOC dynamics helps embed ecology soil microbiome into cycling, which serves to improve biodiversity conservation management strategy under global change. Here, croplands with a gradient were used understand how metabolisms decomposition linked diversity, composition, co‐occurrence networks encompassing archaea, bacteria, fungi, protists, invertebrates. As decreased, diversity prokaryotes eukaryotes also but network complexity showed contrasting patterns: increased due intensified niche overlap, while that decreased possibly because greater dispersal limitation owing breakdown macroaggregates. Despite decrease stocks, capacity was enhanced as indicated by enzyme activity enzymatic stoichiometric imbalance. This could, turn, expedite loss through respiration, particularly slow‐cycling pool. The dominantly driven multitrophic negative (competitive predator–prey) associations, fostered stability metacommunity. Interestingly, abiotic conditions including pH, aeration, nutrient exhibited less significant role. Overall, this study reveals need for C resources across levels maintain functionality declining results loss.

ABSTRACT The established paradigm assumes that drainage may decrease the vast soil organic carbon (SOC) reservoir in global wetlands. Yet can also promote SOC stabilization by fostering accrual of metal-bound (bound OC) upon oxygen exposure. Here, this emergent mechanism is tested for first time at a regional scale, using literature data and nationwide, pairwise survey drained wetlands across China. We show long-term (15–55 years) largely increased metallic protection OC%) non-Sphagnum wetlands, but consistently decreased bound OC% Sphagnum following replacement ‘rust engineer’ herbaceous plants. Improved stock estimates based on 66 profiles reveal OC increases compensate loss unbound components with substantial reactive metals. Metallic wetland hence widespread overlooked heavily influenced vegetational shifts. Incorporating novel into models will improve prediction dynamics under shifting hydrological regimes.

Effective soil organic carbon (SOC) management can mitigate the impact of climate warming. However, response different SOC fractions to warming in abandoned croplands remains unclear. Here, categorizing into particulate and mineral-associated (POC MAOC) with physical fractionation, we investigate responses POC MAOC content temperature sensitivity (Q10) through a 3-year situ experiment (+1.6 °C) across 12 sites China (latitude: 22.33–46.58°N). Our results indicate that unchanged while significantly increases under changes are mainly influenced by root biomass microbial necromass changes, respectively. The Q10 is lower than regardless or control treatment, suggesting represents most persistent least vulnerable fraction within SOC. Collectively, sequestration stable be enhanced short-term Natural recovery generally benefits accrual croplands, but on this ecosystem authors showed enhances these lands.
