Agriculture significantly impacts the global environment, contributing to greenhouse gas (GHG) emissions, air and water pollution, biodiversity loss. As population grows demands higher agricultural output, these environmental are expected intensify. Among contributors, China, with its vast prominent sector, plays a leading role in GHG emissions. Understanding mitigating China is crucial for addressing broader challenges. To address key issues, we conducted study on dynamic impact of variables (agricultural land, fertilizer consumption, energy use agriculture, value-added, forest livestock, fisheries, crop production) emissions by utilizing data from 1990 2020, employed linear non-linear autoregressive distributed lag (ARDL NARDL) models. In study, co-integration analysis confirms long-run relationship between variables, long-term findings ARDL model reveal important insights, increased land use, production, livestock fishery production increases can be reduced increasing long term. Furthermore, asymmetric NARDL regression applied three positive shock results confirm that (AGL+), consumption (FC+), (EUA+) contribute However, adverse shocks (AGL−), (FC−), (EUA−) could compress These offer valuable implications Chinese authorities' focus expanding using more renewable energy, minimizing usage chemicals agriculture. measures help mitigate while promoting sustainable practices.

Nitrogen (N) fertilizer incorporation of efficiency enhancer is a well-established practice aiming at reducing N loss while enhancing crop yield. However, the effect different kinds on use (NUE) and gas are rarely compared poorly comprehended. Here, we conducted field experiment involving combination urease nitrification inhibitor (NI), biological eugenol (DE) bioploymer poly-glutamic acid (PG) their combinations (NI + PG, NI DE, PG DE) to evaluate effects yield, NUE, NH3 volatilization greenhouse emissions (GHGs). Results indicated that NI, significantly enhanced uptake NUE. DE all effective in N2O emission, averagely decreased by 11.13%, 6.83%, 8.29%, respectively, 11.15%, 4.32%, 8.35%, have no significant CO2-C CH4-C fluxes, except increases emission thus global warming potential. The these three enhancers has multiply maize NUE loss. These findings help screen can be more effectively utilized agricultural practices contribute application strategies within systems.

Improving nitrogen use efficiency (NUE) without compromising yield remains a crucial agroecological challenge in theory and practice. Some meta-analyses conducted recent years investigated the impact of (N) fertilizer on crop gaseous emissions, but most are region-specific focused N sources application methods. However, various factors affecting wheat crops global scale not extensively studied, thus highlighting need for comprehensive meta-analysis. Using 109 peer-reviewed research studies (published between 2000 2022) from 156 experimental sites (covering 36.8, 38.6 24.6% coarse, medium, fine texture soils, respectively), we meta-analysis to elucidate suitable management practices key influencing fertilization as function recovery also explained future perspectives efficient crop. Overall, had significant yield. A curvilinear relationship was found rates grain yield, whereas maximum improvement illustrated at 150-300 kg ha -1 . In addition, increased by 92.18% under direct soil incorporation, 87.55% combined chemical organic fertilizers application, 72.86% split application. Site-specific covariates (climatic conditions properties) pronounced efficiency. significantly higher response observed regions with MAP > 800 mm, where MAT remained < 15 °C. Additionally, highest initial AN, AP AK concentrations 20, 10 100-150 mg , respectively, considerably declined increasing these threshold values. Nevertheless, regression analysis revealed declining trend (REN) addition already fertile soils may affect plant uptake RE. Global REN 49.78% followed negative further increase supply properties. Finally, an advanced approach such “ root zone targeted ” is suggested reduce rate save time labor costs while achieving high NUE.

The application of nitrification inhibitors (NIs) is an effective way to reduce soil nitrogen (N) losses and increase crop N uptake. Yet, the efficacy NIs commonly varies with dosages, systems environmental conditions. Hence, clarifying suitable type dosage extremely important for structuring best management regime at a regional scale. Here, based on microcosm experiments, we evaluated influence three widely used [Dicyandiamide, DCD; 3,4-Dimethylpyrazole phosphate, DMPP; 2-chloro-6-(trichloromethyl) pyridine, Nitrapyrin] activity intensively cultivated greenhouse soil. results showed that both DCD DMPP imposed transient inhibition (less than five days) regardless dosages applied, and, contrary, Nitrapyrin presented persistent suppression, longer duration action by higher dosage. Accordingly, incorporation 2% applied rate (w/w) recommendable local intensive production. Further, assessed various (0%, 0.25%, 0.5%, 5%) abundance community groups ammonia oxidizers [i.e., ammonia-oxidizing archaea (AOA), bacteria (AOB) completely (Comammox Nitrospira)] qPCR high-throughput amplicon sequencing. strongly lowered AOB Comammox Nitrospira abundances their richness even lowest also significantly altered structure all tested oxidizers, average relative some major members (i.e., Nitrososphaerales Clade Nitrososphaera, A, Nitrosospira briensis Clade, multiformis A.2 A-associated) obviously responded incorporation. Overall, our findings indicated were more sensitive as compared AOA. obtained here highlight importance optimizing fertilization in vegetable inhibits probably suppressing level herein.

Nitrogen fertilization plays a critical role in promoting plant growth, improving physiological and biochemical traits, enhancing wheat productivity. This study aimed to evaluate the effects of seven nitrogen (N) doses—0, 45, 90, 135, 180, 225, 270 kg N ha−1—on performance under semi-arid subtropical conditions over three consecutive growing seasons (2015–2018). A randomized complete block design (RCBD) was used assess comprehensive set agronomic, physiological, biochemical, nutritional parameters. Key factors examined included grain yield, above-ground biomass, harvest index, total content grains straw, traits such as photosynthetic rate, stomatal conductance, transpiration accumulation soluble proteins, sugars, amino acids. The also incorporated multivariate statistical techniques, multi-trait genotype–ideotype distance index (MGIDI), principal component analysis (PCA), descriptive statistics identify most effective dose. Results indicated that 180 ha−1 (T4) treatment for efficiency, with 135 (T3) showing favorable outcomes. In contrast, higher doses (225 ha−1) led diminished performance, suggesting threshold beyond which becomes counterproductive. These findings support optimal dose maximizing yield quality while contributing more sustainable profitable production.
