The continuous increase of the greenhouse gas nitrous oxide (N2O) in atmosphere due to increasing anthropogenic nitrogen input agriculture has become a global concern. In recent years, identification microbial assemblages responsible for soil N2O production substantially advanced with development molecular technologies and discoveries novel functional guilds new types metabolism. However, few practical tools are available effectively reduce situ flux. Combating negative impacts fluxes poses considerable challenges will be ineffective without successfully incorporating microbially regulated processes into ecosystem modeling mitigation strategies. Here, we synthesize latest knowledge (i) key pathways regulating consumption terrestrial ecosystems critical environmental factors influencing their occurrence, (ii) relative contributions major biological emissions by analyzing natural isotopic signatures using stable isotope enrichment inhibition techniques. We argue that it is urgently necessary incorporate traits biogeochemical order estimation reliability emissions. further propose methodology oriented framework from gene scales more robust prediction future

Knowledge-based nitrogen (N) management, which is designed for a better synchronization of crop N demand with supply, critical global food security and environmental sustainability. Yet, comprehensive assessment on how these management practices affect production, greenhouse gas emission (GHG), pollution in China lacking. We compiled the results 376 studies (1166 observations) to evaluate overall effects seven knowledge-based productivity, nitrous oxide (N2 O) emission, major reactive (Nr) losses (ammonia, NH3 ; leaching runoff), staple grain (rice, wheat, corn) production China. These included application controlled-release fertilizer, nitrification inhibitor (NI) urease (UI), higher splitting frequency fertilizer application, lower basal (BF) proportion, deep placement optimal rate based soil test. Our showed that, compared traditional significantly increased yields by 1.3-10.0%, attributed aboveground uptake (5.1-12.1%) use efficiency (8.0-48.2%). Moreover, reduced GHG Nr losses, 5.4-39.8% N2 O 30.7-61.5% (except NI application), 13.6-37.3% leaching, 15.5-45.0% runoff. The 27.5% (9.0-56.0%), deserves extra-attention. cost benefit analysis indicated that yield profit exceeded corresponding input cost, resulted significant increase net economic 2.9-12.6%. suggest practice can be considered an effective way ensure improve sustainability, while increasing return.

Fertilisers are one of the most important elements modern agriculture. The application fertilisers in agricultural practices has markedly increased production food, feed, fuel, fibre and other plant products. However, a significant portion nutrients applied field is not taken up by plants lost through leaching, volatilisation, nitrification, or means. Such loss increases cost fertiliser severely pollutes environment. To alleviate these problems, enhanced efficiency (EEFs) produced used form controlled release nitrification/urease inhibitors. biopolymers for coating EEFs, tailoring pattern to closely match growth requirement development realistic models predict common have been foci research. In this context, paper intends review relevant aspects new developments use, agronomic, economic environmental drives their formulation process nutrient behaviour. Application complex coacervation technique encapsulation also explored as promising technology produce EEFs.

Abstract Globally, flooding is one of the most damaging abiotic stresses, besides drought, that affects 17 million km 2 land surface annually. Recent research indicates climate change resulting in more extreme weather events, such as or soil waterlogging, negatively affect crop production. Therefore, it imperative to understand how stress crops and develop improved production practices make cropping systems resilient able cope with events. This review paper summarizes current state knowledge on impacts waterlogging losses, nitrogen (N) provides potential management strategies reduce these losses. The factors affecting extent injury plants well plant adaptations under are also discussed briefly. For purpose this review, “flooding” refers situation when all part submerged water, whereas “soil waterlogging” where pores saturated water. Soil promotes N losses through runoff, leaching, denitrification. Potential can be used mitigate include use flood‐tolerant varieties, adjusting practices, improving drainage, practicing adaptive nutrient strategies. However, might site‐ crop‐specific they should validated for their economic viability before developing future plans promote sustainable yields from waterlogged soils.
