Journal ArticleDOI
Nitrous oxide emissions from soils: how well do we understand the processes and their controls?
Klaus Butterbach-Bahl,Elizabeth M. Baggs,Michael Dannenmann,Ralf Kiese,Sophie Zechmeister-Boltenstern +4 more
TL;DR: Improved process understanding, building on the increased use of isotope tracing techniques and metagenomics, needs to go along with improvements in measurement techniques for N2O (and N2) emission in order to obtain robust field and laboratory datasets for different ecosystem types.
Journal ArticleDOI
Nitrogen balance in forest soils: nutritional limitation of plants under climate change stresses
TL;DR: The present understanding of ecosystem N cycling in N-limited forests and its interaction with extreme climate events, such as heat, drought and flooding are summarized and the consequences of drying-wetting cycles on N cycling are discussed.
Journal ArticleDOI
Grazing-induced reduction of natural nitrous oxide release from continental steppe
Benjamin Wolf,Xunhua Zheng,Nicolas Brüggemann,Weiwei Chen,Michael Dannenmann,Xingguo Han,Mark A. Sutton,Honghui Wu,Zhisheng Yao,Klaus Butterbach-Bahl +9 more
TL;DR: The results show that the stimulatory effect of higher stocking rates on nitrogen cycling and, hence, on N2O emission is more than offset by the effects of a parallel reduction in microbial biomass, inorganic nitrogen production and wintertime water retention.
Journal ArticleDOI
Tree girdling provides insight on the role of labile carbon in nitrogen partitioning between soil microorganisms and adult European beech
Michael Dannenmann,Judy Simon,Rainer Gasche,Jan Holst,Pascale Sarah Naumann,Ingrid Kögel-Knabner,Heike Knicker,Helmut Mayer,Michael Schloter,Rodica Pena,Andrea Polle,Heinz Rennenberg,Hans Papen +12 more
TL;DR: Overall, the girdling-induced decline of rhizodeposition altered the competitive balance of N partitioning in favour of beech and its most abundant mycorrhizal symbiont and at the expense of heterotrophic N turnover by free living microorganisms in soil.
Journal ArticleDOI
Effects of soil moisture and temperature on CO2 and CH4 soil–atmosphere exchange of various land use/cover types in a semi-arid grassland in Inner Mongolia, China
Xing Wu,Xing Wu,Zhisheng Yao,Nicolas Brüggemann,Zhenyao Shen,Benjamin Wolf,Michael Dannenmann,Xunhua Zheng,Klaus Butterbach-Bahl +8 more
TL;DR: In this article, the combined effects of soil moisture and temperature as well as drying/rewetting and freezing/thawing on soil-atmosphere exchange of CO2 and CH4 of the four dominant land use/cover types (typical steppe, TS; sand dune, SD; mountain meadow, MM; marshland, ML) were investigated.
