Abstract Many agricultural regions in China are likely to become appreciably wetter or drier as the global climate warming increases. However, impact of these change patterns on intensity soil greenhouse gas (GHG) emissions (GHGI, GHG per unit crop yield) has not yet been rigorously assessed. By integrating an improved ecosystem model and a meta‐analysis multiple field studies, we found that is expected cause 20.0% yield loss, while stimulating by 12.2% between 2061 2090 China's regions. A wetter‐warmer (WW) would adversely equal basis lead 1.8‐fold‐ increase relative those drier‐warmer (DW) climate. Without water limitation/excess, extreme heat (an more than 1.5°C average temperature) during growing season amplify 15.7% simultaneously elevating 42.5% compared below 1.5°C. when coupled with drought, it aggravate loss 61.8% without reducing corresponding emissions. Furthermore, emission WW 22.6% DW Under this intense climate, use nitrogen fertilizer 37.9% necessarily gaining advantage These findings suggest threat world efforts reduce may be great even greater world.

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.

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.

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.
