This study shows that wild rice harbors a higher abundance of nitrogen-fixing genes in the rhizosphere, while domesticated rice has more genes associated with nitrous oxide production. Changes in denitrifier abundance, denitrification gene mRNA levels, nitrous oxide emissions, and denitrification in anoxic soil microcosms amended with glucose and plant residues

Wetlands are frequently regarded as weak carbon dioxide (CO 2) sinks, the largest natural sources of methane (CH 4), and weak sources of nitrous oxide (N 2 O). Anthropogenic activities and climate change-induced nitrogen (N) enrichment may affect wetland carbon (C) and N cycling via soil microbes, consequently modifying the original greenhouse Request PDF | On May 22, 2013, Hongying Sun and others published The effects of plant diversity on nitrous oxide emissions in hydroponic microcosms | Find, read and cite all the research you need Organic materials returned to the field have a significant effect on N2O emissions from agricultural fields, but the knowledge about the relationship

Arbuscular mycorrhizal fungi reduce soil nitrous oxide emission

Aims Perennial forages in rotation with annual crops can improve agricultural resilience by increasing soil organic carbon. However, how nitrogen (N) sources interact with rotation diversity to influence soil nitrous oxide (N2O) emissions is not well understood. Methods During three snow-free seasons, N2O emissions, crop yields, and ancillary variables were Forests are recognized as the largest natural source of nitrous oxide (N2O) emissions on land, with deforestation drastically reducing the cover and biodiversity of native forests worldwide. Yet, how losses in forest biodiversity affect soil N2O

Nitrous oxide (N 2 O) is a potent greenhouse gas (GHG) and an ozone-depleting substance. The presence of plants in an ecosystem can either increase or decrease N 2 O emissions, or play a negligible role in driving N 2 O emissions. Here, we conducted a meta-analysis comparing ecosystem N 2 O emissions from planted and unplanted systems to Soils are major sources and sinks of nitrous oxide (N2O). The main pathway of N2O emission is performed through soil denitrification; however, the upt

However, the impacts of human activities on N2O emissions through biodiversity loss or primary productivity changes in natural ecosystems have rarely been assessed. Here, we analyzed the effects of vegetation attributes such as plant diversity and production, as drivers of N2O emission rates, in addition to environmental factors.

Long-term multi-meta-omics resolves the ecophysiological

Our analyses reveal that tree diversity has a significant negative effect on soil N2O emissions, primarily driven by a decrease in N2O production associated with denitrification. More specifically, we showed that reductions in N2O emissions with tree diversity can be attributed to a decrease in the availability of soil inorganic nitrogen. Request PDF | On Aug 1, 2020, Drew A.

With the IPCC aiming to slash global greenhouse gas (GHG) emissions by 80% before 2100, urgent advancements in technologies are imperative to curtail nitrous oxide (N 2 O) emissions from agricultural systems. The extensive cultivation of rice-wheat and the amplified utilization of commercial fertilizers have led to elevated N 2 O Nitrous oxide (N 2 O) is one of the three important greenhouse gases (CO 2, CH 4 and N 2 O) contributing to global climate change. The excessive amounts of soil nitrogen (N) from fertilization or deposition are the main source of increased N 2 O emission. Arbuscular mycorrhizal fungi (AMF, plant symbiotic soil fungi) are widespread in terrestrial ecosystems, Forests are recognized as the largest natural source of nitrous oxide (NO) emissions on land, with deforestation drastically reducing the cover and biodiversity of native forests worldwide. Yet, how losses in forest biodiversity affect soil NO fluxes remains poorly understood. Here, we combined a global tree diversity–forest soil NO data set, including 201 paired comparable observations

Aims Grasslands are important agricultural production systems, where ecosystem functioning is affected by land management practices. Grass ABSTRACT Forests are recognized as the largest natural source of nitrous oxide (N 2 O) emissions on land, with deforestation drastically reducing the cover and biodiversity of native forests worldwide.

Plant metabolites significantly affect soil nitrogen (N) cycling, but their influence on nitrous oxide (N 2 O) emissions has not been quantitatively analyzed on a global scale. We conduct a comprehensive meta-analysis of 173 observations from 42 articles to evaluate global patterns of and principal factors controlling N 2 O emissions in the presence of root exudates Our analyses reveal that tree diversity has a significant negative effect on soil N2O emissions, primarily driven by a decrease in N2O production associated with denitrification. More specifically, we showed that reductions in N2O emissions with tree diversity can be attributed to a decrease in the availability of soil inorganic nitrogen. The conversion of biomass improved by diversity to bioenergy can further reduce greenhouse gas emissions. We established 108 microcosms to simulate CWs to explore the effects of adding CNTs to wastewater and assembling plant diversity on ammonia (NH3), nitrous oxide (N2 O), and methane (CH 4) emissions from CWs.

Abstract Previous studies have shown that plant diversity can improve the wastewater purification efficiency of constructed wetlands (CWs), but its effect on the nitrous oxide (N2 O) emission in CWs has been unknown. Biochar has been proposed as a soil amendment in vegetable fields, where the widespread use of plastic film leads to significant retention of microplastics (MPs) in the soil. However, the interactive effect of biochar and MPs on plant growth and soil functions remains poorly understood. Here, we conducted a pot experiment to examine the effects of biochar
