This study investigated the effects of inoculating thermophilic and mature composts on maturity, gaseous emissions, bacterial communities during co-composting kitchen waste pig manure. Results showed that temperature peaked day 4 inoculation compost amendment, which was earlier than control treatment 8. In particular, GI inoculated higher (88.65%) other treatments (GI≤61%) 35. The addition promoted enrichment Bacillus Planifilum, accelerated organic matter degradation, enhanced maturity. Inoculation with reduced CH4 emissions by 50.66%, owing to methane-oxidizing bacteria (norank_f_Methylococcaceae). Furthermore, decreased NH3 36.16% through physical absorption microbial activity (reducing NH4+ production). amendment increased N2O denitrification nitrate reduction function.

Climate change and cadmium (Cd) contamination pose severe threats to rice production food security. Biochar (BC) has emerged as a promising soil amendment for mitigating these challenges. To investigate the BC effects on paddy upon GHG emissions, Cd bioavailability, its accumulation, meta-analysis of published data from 2000 2023 was performed. Data Manager 5.3 GetData plot Digitizer software were used obtain process selected parameters. Our results showed significant increase 18% in pH with sewage sludge application, while 9% organic carbon (SOC) using bamboo chips BC. There reduction bulk density (8%), but no observed porosity, except wheat straw which reduced porosity by 6%. Sewage significantly dioxide (CO2) 7–8% municipal biowaste methane (CH4) emissions 2%. In case heavy metals, sunflower seedshells-derived materials husk bioavailable soils 24% 12%, respectively. uptake roots lowered considerably addition kitchen waste (22%), peanut hulls (21%), corn cob (15%) based Similarly, cotton sticks, waste, hulls, restricted translocation shoots 22%, 27%, 20%, 19%, respectively, sawdust husk-based effective reducing accumulation grains 25% 13%. Regarding yield, sticks-based increased yield 37% Cd-contaminated soil. The demonstrated that is an multi-pronged strategy sustainable resilient cultivation lowering greenhouse gas improving yields under increasing threat climate change.

Climate change is a contemporary global challenge that requires comprehensive solutions to mitigate its adverse effects. All human activities contribute climate change, mainly through atmospheric emissions of greenhouse gases (GHGs), such as nitrous oxide (N2O), carbon dioxide (CO2), and methane (CH4). While most these are primarily due fossil fuel use, agriculture livestock production also significant share approximately 12% emissions. Most processes implemented within an animal husbandry unit associated with gas emissions, including manure management. This review explores the interconnection between management practices, highlighting potential for sustainable approaches mitigating GHG The key strategies management, anaerobic digestion, nutrient composting, separation treatment, improved storage handling, discussed, they in different systems (ruminants, poultry, pigs). Despite technological progress, there still place further improving approaches, especially non-ruminant species leading higher mitigation reduction Moreover, policy support incentives practices crucial widespread adoption.

Abstract Plant metabolites significantly affect soil nitrogen (N) cycling, but their influence on nitrous oxide (N 2 O) emissions has not been quantitatively analyzed a global scale. We conduct comprehensive meta‐analysis of 173 observations from 42 articles to evaluate patterns and principal factors controlling N O in the presence root exudates extracts. Overall, plant promoted by about 10%. However, effects soils varied with experimental conditions properties both soils. Primary metabolites, such as sugars, amino acids, organic strongly stimulated emissions, an average 79%, while secondary phenolics, terpenoids, flavonoids, often characterized biological nitrification inhibitors (BNIs) denitrification (BDIs), reduced 41%. The emission mitigation BNIs/BDIs were closely associated texture pH, increasing clay content pH acidic neutral soils, decreasing alkaline furthermore present incubation experiments that show three metabolite types act BNIs reduce 32%–45%, primary classes possess stimulatory effect 56%–63%, confirming results meta‐analysis. Our highlight potential role application range specific biomitigation provide new parameters for models should help improve accuracy model predictions.

Abstract Nitrous oxide (N 2 O) emissions from livestock manure contribute significantly to the growth of atmospheric N O, a powerful greenhouse gas and dominant ozone‐depleting substance. Here, we estimate global O during 1890–2020 using tier approach 2019 Refinement 2006 IPCC Guidelines. Global increased by ~350% 451 [368–556] Gg year −1 in 1890 2042 [1677–2514] 2020. These contributed ~30% anthropogenic decade 2010–2019. Cattle most (60%) increase, followed poultry (19%), pigs (15%), sheep goats (6%). Regionally, South Asia, Africa, Latin America dominated since 1990s. Nationally, largest were found India (329 ), China (267 United States (163 Brazil (129 ) Pakistan (102 2010s. We substantial impact productivity, specifically animal body weight milk yield, on emission trends. Furthermore, large spread existed among different methodologies estimates manure, with our results 20%–25% lower than those based This study highlights need for robust time‐variant model parameterization continuous improvement factors enhance precision inventories. Additionally, urgent mitigation is required, as all available inventories indicate rapid increase recent decades.
