Straw return and plastic film mulching are two critical management measures that not only maintain high stable crop yields, but also have a significant impact on the ecological environment. However, there is still lack of research comprehensive effects straw different treatments Thus, 2-year field experiment was conducted six treatments, which included main namely (SR) non-straw (NR), three sub-treatments, no (CK), (PM) fully biodegradable (BM), were applied in garlic cropping system. Based life cycle assessment method, endpoint damage categories, resource consumption, global warming potential, environmental acidification, eutrophication, human health, ecotoxicity, assessed. Furthermore, we evaluated costs economic benefits optimized treatment used mulch off-farm. The results indicated impacts damages system ranked as consumption. SR-BM had lowest composite index at 27.68 per unit area, followed by SR-PM 27.75. All categories for PM BM lower than CK t yield, with being most economically efficient, yielding 3691.03 CNY·t−1 exceeding SR-CK 7.26%. Fertilizer inputs primary contributor to accounting about 72.80% these five impacts. Crop protection significantly affected helped minimize pesticide use, thereby reducing potential health Compared incineration waste power generation, generation recycling granulation offered positive more effective offset strategies. In conclusion, synergistic cultivation measure offers both benefits. For mulch, can be reduced granulation.

Intercropping has been widely used in arid and semi-arid regions because of its high yield, stable productivity, efficient utilization resources. However, recent years, the yield traditional intercropping is mainly attributed to large amount purchased resources such as water fertilizer, plastic film, mechanical power. It leads decline cultivated land quality phenomenon premature root-canopy senescence intercrops become increasing serious. So, application faces major challenges crop production. In this paper, manifestations, occurrence mechanisms, agronomic regulatory pathways were analyzed detail. The physiological ecological characteristics delay crops are reviewed paper. main based on above- blow-ground interactions, include collocation varieties, spatial arrangement, fertilizer management, tillage mulch practices. Future research fields should focus aspects selecting breeding special molecular biology techniques, developing or applying models predict evaluate process intercrops. Comprehensive analysis evaluation different results could provide a basis for enhancing through adopting innovative technologies regulating physio-ecological This would support development adoption high-yield, efficient, sustainable systems areas with more people less land, abundant light heat

Abstract BACKGROUND The shortage of water resources and the increase greenhouse gas emissions from soil seriously restrict sustainable development agriculture. Under premise ensuring a stable yield winter wheat through reasonable irrigation scenario, identifying suitable straw returning method will have positive effect on agricultural carbon sequestration emission reduction in North China Plain. RESULTS Straw burying (SR) mulching (SM) were adopted based traditional tillage under growing season 2020–2021 2021–2022. Three scenarios used for each method: no (I0), 60 mm at jointing stage (I1), heading stages (I2). Soil moisture, respiration rate, cumulative CO 2 emissions, yield, use efficiency (WUE) (CEE) mainly studied. results showed that, compared to SM, SR improved utilization enhanced sequestration. reduced rate two seasons, increased by increasing spike numbers. In addition, with an amount irrigation, increased. SR‐I1 treatment, WUE CEE highest. increases crop yields same time as reducing emissions. CONCLUSION combination is which can improve reduce NCP. © 2023 Society Chemical Industry.

Organic fertilizer is utilized to improve the organic carbon levels in arable soils, which helpful for soil quality improvement and crop yield increase. However, after-effect of varies among regions with different temperature precipitation conditions, extent impact remains unknown. This study aimed investigate varying rainfall conditions on accumulation after application. A meta-analysis 168 peer-reviewed studies published between 2005 2022 involving a total 464 trials was conducted. The following discovered: (1) In major grain-producing areas China, there significant positive correlation (p < 0.01) latitude content. Meanwhile, had negative (2) increase inhibited storage. effect application low-temperature significantly increased by 60.93% compared mid-temperature areas, 69.85% high-temperature areas. average annual affected as follows: 400–800 mm > 400 more than 800 mm. (3) influence climatic depending specific tillage practice. To use efficiency eliminate greenhouse gas emissions, liquid fertilizers abundant trace nutrients amino acids, take advantage releasing swiftly have better fertilization effect, could be an alternative traditional fertilizers.

Abstract Organic fertilizers are essential for enhancing soil organic carbon (SOC) levels and promoting sustainable agriculture. The mechanisms of sequestration in upland red soils using various materials not well understood. Here, the impact fertilization strategies on SOC fractions, functional groups, iron oxides, aggregates was investigated to clarify protective underlying preservation. Six regimes were examined: no (CK), mineral fertilizer (CF), 60% (RF), RF + straw (RFS), pig manure (RFP), vermicompost (RFV). results demonstrated that contents significantly increased by 62.5% RFP 63.1% RFV compared CF treatment, with particulate (POC) being primary contributor. Scanning electron microscopy X‐ray photoelectron spectroscopy treatments induced formation denser flock‐like aromatic C content, respectively. Fourier transform infrared analysis indicated treatment exhibited highest abundance groups among all treatments. POC highly positively correlated chemical properties, aggregates, poorly crystalline rings. Structural equation models directly promoted accumulation, while provided physical protection aggregate formation. Furthermore, indirectly facilitated development mineral‐associated via biochemical properties Overall, application enhanced protection, immobilization, recalcitrance (alkyl C, C) carbon, facilitating stability. This study highlights importance management increasing storage maintaining global balance.
