Linking N2O emissions from biochar-amended soil to the structure and function of the N-cycling microbial community
Nitrous oxide (N2O) contributes 8% to global greenhouse gas emissions. Agricultural sources represent about 60% of anthropogenic N2O emissions. Most agricultural N2O emissions are due to increasedExpand
Biochar as an Electron Shuttle between Bacteria and Fe(III) Minerals
Biochar influences soil fertility, N2O emissions, and atmospheric CO2 budgets, and because of its quinone and aromatic structures, it is redox-active. Here we demonstrate that biochar concentrationsExpand
Organic coating on biochar explains its nutrient retention and stimulation of soil fertility
Amending soil with biochar (pyrolized biomass) is suggested as a globally applicable approach to address climate change and soil degradation by carbon sequestration, reducing soil-borneExpand
Soil biochar amendment shapes the composition of N2O-reducing microbial communities.
Soil biochar amendment has been described as a promising tool to improve soil quality, sequester carbon, and mitigate nitrous oxide (N2O) emissions. N2O is a potent greenhouse gas. The main sourcesExpand
Does soil aging affect the N2O mitigation potential of biochar? A combined microcosm and field study
The application of biochar as a soil amendment to improve soil fertility has been suggested as a tool to reduce soil‐borne CO2 and non‐CO2 greenhouse gas emissions, especially nitrous oxide (N2O).Expand
Biochar affects community composition of nitrous oxide reducers in a field experiment
Abstract N2O is a major greenhouse gas and the majority of anthropogenic N2O emissions originate from agriculturally managed soils. Therefore, developing N2O mitigation strategies is a key challengeExpand
The distribution of active iron‐cycling bacteria in marine and freshwater sediments is decoupled from geochemical gradients
Microaerophilic, phototrophic and nitrate-reducing Fe(II)-oxidizers co-exist in coastal marine and littoral freshwater sediments. However, the in situ abundance, distribution and diversity ofExpand
Gas entrapment and microbial N2O reduction reduce N2O emissions from a biochar-amended sandy clay loam soil
Nitrous oxide (N2O) is a potent greenhouse gas that is produced during microbial nitrogen transformation processes such as nitrification and denitrification. Soils represent the largest sources ofExpand
Elucidating the Impacts of Biochar Applications on Nitrogen Cycling Microbial Communities
Abstract Biochar has been shown to improve soil function through increased cation and anion exchange capacity, soil water retention, increased soil buffer capacity, and enhanced microbial growth.Expand
Soil biochar amendment affects the diversity of nosZ transcripts: Implications for N2O formation
Microbial nitrogen transformation processes such as denitrification represent major sources of the potent greenhouse gas nitrous oxide (N2O). Soil biochar amendment has been shown to significantlyExpand
