Abstract Biological nitrogen fixation (BNF) by methanotrophic bacteria has been shown to play an important role in maintaining fertility. However, this process is still limited aerobic methane oxidation with sufficient oxygen. It remained unknown whether and how BNF proceeds hypoxic environments. Herein, we incubated paddy soils a ferrihydrite-containing mineral salt medium enrich the presence of (20%, v/v) under oxygen constraints (0.27%, v/v). The resulting microcosms showed that ferrihydrite-dependent significantly contributed (81%) total BNF, increasing 15N rate 13-fold from 0.02 0.28 μmol 15N2 (g dry weight soil) -1 d−1. was reduced 97% when ferrihydrite omitted, demonstrating involvement BNF. DNA stable-isotope probing indicated Methylocystis, Methylophilaceae, Methylomicrobium were dominant methanotrophs/methylotrophs assimilated labeled isotopes (13C or 15N) into biomass. Metagenomic binning combined electrochemical analysis suggested Methylocystis Methylophilaceae had potential perform methane-induced likely utilized riboflavin c-type cytochromes as electron carriers for reduction. concluded mediated solely conjunction iron-reducing bacteria. Overall, study revealed previously overlooked yet pronounced coupling iron-dependent improves our understanding zones.

The demand for agricultural goods is currently higher than it has ever been before due to the expansion of world population. This resulted in conversion grassland into areas, development high-energy-intensive agriculture production systems, and use additional chemical organic inputs systems. output greenhouse gases (GHGs) also increased same way. Carbon dioxide (CO2), Nitrous Oxide (N2O), Methane (CH4) most significant (GHGS) that are producing a variety disastrous consequences climate change. Despite fact CH4 N2O released smaller amounts CO2, they have larger Global Warming Potential CO2. analysis begins with an examination variables contribute gas emissions, which covers both inorganic factors (such as nitrogen, phosphorus, potassium fertilizers) (Animal manure, composted bio-solids, crop species). study underlines need more research intricate interactions physical, chemical, biological elements near future. Field crops other cereals, such legumes, oilseeds, vegetables, fruits, account amount (GHG) emissions. Precision may be viable option increasing efficiency. Optimal management practices should implemented farm field settings through methodical, site-specific approaches.

A large amount of nitrogen (N) fertilizer is required for paddy cultivation, but use efficiency (NUE) in farming low (20–40%). Much the unutilized N potentially degrades quality soil, water, and air disintegrates functions different ecosystems. It a great challenge to increase NUE sustain rice production meet food demand growing population. This review attempted find out promising management practices that might while reducing trade-off between environmental pollution. We collected collated information on associated barriers. set existing crop, strategies can be suggested increasing NUE, which, however, not capable halve waste by 2030 as stated “Colombo Declaration” United Nations Environment Program. Therefore, more efficient tools are yet developed through research extension. Awareness-raising campaign among farmers must against their misunderstanding higher provides yields. The findings help policymakers formulate suitable policies regarding eco-friendly wetland cultivation ensure better utilization costly fertilizer.

Abstract Ensuring global food security under present and futuristic scenario of climate change accompanied by expanding population is major concern worldwide. Researchers across the world are focusing on sustainable agronomic practices to combat induced issues like desertification, reduction in crop yield, pest outbreaks, soil health. Biochar has demonstrated positive effects plant growth, development, fruit quality, carbon capture sequestration. Studies indicate that biochar amendments can enhance health, growth development as well help combating abiotic stressors. several properties make it an attractive amendment, including high porosity, surface area, water-holding capacity, ability increase microbiota, which turn promote nutrient uptake reduce erosion. Environmentally, biochar’s degrade organic pollutant sequester makes a very addition agriculture. Nonetheless, also been reported have potential hazardous impacts human health associated with possible leakage toxic elements particulate matter pollution. However, lack exhaustive studies detail all aspects application agroecosystem impedes decision making its overall usability There exists need for comprehensive review cover important supplementation. This provides thorough overview multifaceted biochar, encompassing soil, environment, while exploring limitations along application.

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%.

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.

This study presents detailed crop and gas flux data from two years of rice production at the experimental farm ICAR-Indian Agricultural Research Institute, New Delhi, India. In comparing 4 nitrogen (N) fertiliser regimes across cultivars (CRD 310, IR-64, MTU 1010, P-44), we have added to growing evidence environmental costs in region. The shows that cultivar can impact yields both grain, total biomass produced given circumstances, with CRD 310 showing consistently high use efficiency (NUE) for compared other tested varieties, but not necessarily highest grain yield, which was P-44 this experiment. While NUE did vary depending on treatments (ranging 41% 73%), translate directly into reduction emissions ammonia (NH3) nitrous oxide (N2O). Emissions were relatively similar different regardless NUE. Conversely, agronomic practices reduced N losses associated higher yield. terms application, outstanding very methane (CH4) as a result incorporating farmyard manure (FYM) paddies, dominated overall effect global warming potential. nitrification urease inhibiting substances decreased N2O overall, NH3 unaffected (or slightly higher). Overall, greatest greenhouse (GHG) came reducing irrigation water fields, resulting N2O, significantly less CH4 emissions, net GHG emission continuous flooding. genetic differences generated more variation yield than management (excluding controls), whereas agronomy larger genetics concerning gaseous losses. suggests mixed approach needs be applied when attempting reduce pollution potential swapping synergies need considered. Finding right balance cultivar, technique type could while getting it wrong considerably poorer pollution.

In rice production greenhouse gas emission (GHG) reduction is an important task for many countries, Tanzania included. Of global agricultural GHG emitted from fields, about 30 and 11% are represented by CH 4 N 2 O, respectively. For successful climate smart cultivation, management practices, including nitrogen fertilization two key crucial components that need evaluation. The objective of this study was to evaluate the crop practices on yield gases in paddy production, Experiments were designed split-plot randomized complete block replicated three times.
