Mulch is an important measure for improving agricultural productivity in many semiarid regions of the world. However, impacts various mulching materials on soil hydrothermal characteristics, enzyme activity, and potato yield fields have not been comprehensively explored. Thus, a two-growing-season field experiment (2020–2021) with four treatments (SSM, straw strip mulching; PMP, plastic film large ridge; PMF, double ridge-furrow full CK, no conventional planting as control) was conducted to analyze activities Loess Plateau Northwest China. The results indicated that practices had positive effect moisture, SSM, PMF increasing by 7.3%, 9.2%, respectively, compared CK. Plastic significantly increased temperature 1.3 °C, reduced 0.7 °C 0–30 cm layers whole growth period. On average, urease activity 0–40 14.2%, 2.8%, 2.7%, enhanced sucrase 19.2%, 8.6%, 5.7%, catalase 9.6%, while SSM decreased 10.1%. Mulching tuber water use efficiency based dry (WUE), 18.6%, 31.9%, 29.7%, WUE 50%, 57.0% over correlation analysis revealed moisture main factor influencing (r = 0.95**). could improve environment, regulate activities, promote increase. As sustainable protective measure, conducive ecological environment farmland development regional organic agriculture.

Introduction Tropical regions are characterized by high temperatures and abundant rainfall, which facilitate rapid carbon mineralization. However, research on soil organic conversion efficiency (Esoc) in these areas is currently constrained a lack of robust data support. Methods This study used nylon - bags with typical tropical materials (pineapple leaf (PAL), banana stems (BAS), coconut husk (CCH), fertilizer (OF)) to explore how mixing straw latosol impacts products, understand the relationships among Esoc, material composition (glycolipid, hemicellulose, cellulose, lignin), enzyme activity. Results CCH had highest from 37.79% 96.87%, followed OF 26.71%–63.12%. The Esoc PAL BAS was 34.57% 25.32% at 90 days, 7.59% 2.55% 1080 days. main factor that determines difference materials. Compared CK treatment, for 90_days mainly O–alkyl–C, anomertic–C, N–alkyl/methoxyl–C, an unstable structure. decomposition products consisted aromatic–C, carbonyl–C, N–alkyl/methoxyl–C. increased mixed N–alkyl/methoxyl–C anomertic–C. In short-term (90 days), PAL, BAS, quantity diversity microorganisms, as well activities xylosidase cellobiohydrolase. enhanced phenol oxidase activity maintained microbial biomass stabilityin long-term (1080 days). Discussion revealed changes under different promotion effects biomass, short term maintenance stability later period were investigated, provided new basis further exploring function mechanism microorganisms ecosystems.

Despite the global imperative to enhance carbon sequestration in agricultural landscapes, saline–alkali soils present distinctive soil–microbe constraints that limit our understanding of optimal management strategies. This study addresses critical knowledge gaps regarding mechanistic relationships between bacterial community structure and stabilization processes soil. A three-year field experiment was conducted Yellow River Delta, China, with two N levels (N1, 270 kg ha−1; N2, 210 ha−1) three C treatments (S0, 0 S1, 5000 S2, 10,000 ha−1). SOC by straw incorporation increased 16.34–22.86% 8.18–11.91%, no significant difference S1 S2 treatments, because specific mineralization rate (SCMR) treatment 13.80–41.61% higher than treatment. The reduced nitrogen application (N2) enhanced efficiency 3.40–12.97% compared conventional rates, particularly when combined half incorporation. Furthermore, N1S1 treatment, N2S1 induced qualitative transformations chemistry, increasing aromatic compounds (28.79%) while reducing carboxylic fractions (10.06%), resulting structural stability sequestered carbon. Bacterial analysis revealed shifts composition under different treatments. Half (S1) abundance oligotrophic strategists (Verrucomicrobiae Acidimicrobiia) decreasing copiotrophic bacteria (Bacteroidia), indicating a transition from r-strategy k-strategy microbial communities fundamentally altered cycling. were beneficial stabilize composition, reduce optimize survival strategy, thus achieve sequestration.
