Biogas digestate as substrate and vector for the introduction of N2O-respiring bacteria to agricultural soil
Jonassen, Kjell Rune (Phd Thesis;2021:53, Doctoral thesis, 2021)Anthropogenic nitrous oxide (N2O) emissions are largely driven by the input of N-based fertilizers in agriculture. N2O emissions from agricultural soils in Europe are estimated to 0.51 Tg annually (Fig. I), which sums to ... -
Compost and N2O-reducing Microbes as Possible Stabilizers of Biosolids
Eide, Lars Johan (Master thesis, 2021)Biosolids generated from dewatering the end-product of sludge treatment, digestate, are rich in nitrogen, phosphorous and recalcitrant carbon, and are often utilized as fertilizers/soil conditioners in agriculture. Biosolids ... -
Denitrification as an N2O sink
Conthe, Monica; Lycus, Pawel Michal; Arntzen, Magnus Øverlie; da Silva, Aline Ramos; Frostegård, Åsa; Bakken, Lars; Kleerebezem, Robbert; Loosdrecht, Mark C.M. van (Journal article; Peer reviewed, 2018)The strong greenhouse gas nitrous oxide (N2O) can be emitted from wastewater treatment systems as a byproduct of ammonium oxidation and as the last intermediate in the stepwise reduction of nitrate to N2 by denitrifying ... -
Effect of calcareous and siliceous amendments on N2O emissions of a grassland soil
Todorcic Vekic, Teodora; Nadeem, Shahid; Molstad, Lars; Martinsen, Vegard; Hiis, Elisabeth Gautefall; Bakken, Lars; Rütting, Tobias; Klemedtsson, Leif; Dörsch, Peter (Peer reviewed; Journal article, 2023)Liming of acidic agricultural soils has been proposed as a strategy to mitigate nitrous oxide (N2O) emissions, as increased soil pH reduces the N2O/N2 product ratio of denitrification. The capacity of different calcareous ... -
Excessive use of nitrogen in Chinese agriculture results in high N2O/(N2O+N2) product ratio of denitrification, primarily due to acidification of the soils
Qu, Zhi; Wang, Jingguo; Almøy, Trygve; Bakken, Lars (Journal article; Peer reviewed, 2014) -
High cell density cultivation by anaerobic respiration
Maråk, Marte Mølsæter; Kellermann, Ricarda; Bergaust, Linda Liberg; Bakken, Lars (Peer reviewed; Journal article, 2024) -
High-resolution denitrification kinetics in pasture soils link N2O emissions to PH, and denitrification to c mineralization

Higher N2O emission by intensified crop production in South Asia
Raut, Nani; Sitaula, Bishal K.; Bakken, Lars; Bajracharya, Roshan Man; Dörsch, Peter (Journal article; Peer reviewed, 2015)Intensification of food production in Nepal has been found to acidify the soils and hence increase their apparent propensity to emit N2O as measured by the N2O/(N2+N2O) product ratio of denitrification during standardized ... -
Impaired Reduction of N2O to N2 in Acid Soils Is Due to a Posttranscriptional Interference with the Expression of nosZ
Liu, Binbin; Frostegård, Åsa; Bakken, Lars (Journal article; Peer reviewed, 2014)Accumulating empirical evidence over the last 60 years has shown that the reduction of N2O toN2 is impaired by low soil pH, suggesting that liming of acid soils may reduce N2O emissions. This option has not gained much ... -
