Abstract Long‐term straw mulching was known to change soil nutrient content, aggregate distribution and extracellular enzyme activities. However, the impact of long‐term on microbial limitations carbon‐use efficiency (CUE st ) within aggregates remains unclear. To fill gap, we conducted a 10‐year field experiment in semi‐arid region used an ecoenzymatic stoichiometry model quantify resource under mulching. We studied effects two measures (plastic film [FM] [SM], with no as control [CK]) content aggregates. The results show that compared FM, SM increased proportion larger >2 mm decreased 2–0.25 classes. Additionally, FM resulted carbon (C) phosphorus (P) soil, particularly class, while alleviated these constraints. This effect primarily attributed increase organic (SOC) biomass (C m ), especially enhanced associated (>2 mm) activities carbon–nitrogen (C–N)‐acquiring enzymes. also high CUE by influencing P limitation. Random forest analysis indicates abiotic factors, SOC total nitrogen (TN), were main drivers These findings suggest material determines development allocation Thus, study provides valuable insights for formulating effective management strategies regions.

Rain-fed potato (Solanum tuberosum) fields in drylands significantly contribute to nitrous oxide (N2O) emissions, making them an important focus of agricultural greenhouse gas research. Film mulching and ridging are key methods cultivation. Investigating the impact these on N2O nitrifying/denitrifying functional genes, microbial communities can provide a theoretical basis for soil emission reduction more sustainable dryland agriculture. We examine effects flat tillage with mulching, ridge without under natural rainfall conditions Wuchuan County, China. fluxes were monitored using static (dark) chamber chromatography. Real-time quantitative PCR (q-PCR) was used quantify abundances nitrifying denitrifying bacteria related emissions at various potato-growth stages. Illumina high-throughput sequencing investigate community structure by targeting 16S rRNA genes; elements (soil temperatures moisture) analyzed. Mulching indirectly influence gene copy numbers, altering temperature moisture. Cumulative intensity both consistently higher during potato-growing period. Ammonia-oxidizing archaea main microorganisms that control nitrification-coupled denitrification also being mechanism contributing high dry–wet cycles. Increased moisture elevated numbers. The combination effectively uses characteristics practices, Nitrospira dominant genus, increases emissions.

Introduction Plastic film mulching has been widely used to enhance soil hydrothermal conditions and increase crop yields in cool, semi-arid areas. However, its impact on microbial carbon metabolic activity functional diversity during plant growth remains unclear despite their important roles nutrient cycling quality evaluation. Methods This study the Biolog EcoPlate technique investigate dynamics driving factors of at different maize stages following plastic mulching. Results discussion The results revealed that significantly increased activities [represented by average well color development (AWCD)] 300% seedling stage 26.8% maturity but decreased it 47.4% flowering compared control (without mulching). A similar trend was observed for index. Redundancy analysis identified moisture (SM), temperature (ST), dissolved organic (DOC), biomass (MBC), bacteria amounts as primary influencing changes source utilization. mulch treatment SM all stages, while warming effect disappeared stage. Soil DOC, MBC, bacterial populations were notably higher under lower Pearson correlation showed SM, ST, positively correlated with utilization classes, AWCD, indexes after Furthermore, grain yield water use efficiency 142 129%, respectively, In conclusion, enhanced improving decrease capacity highlights supplementing sources should be considered continuous sustain or farmland productivity quality.
