Journal ArticleDOI
Microbial and Faunal Interactions and Effects on Litter Nitrogen and Decomposition in Agroecosystems
Michael H. Beare,Robert W. Parmelee,Paul F. Hendrix,Weixin Cheng,David C. Coleman,D. A. Crossley +5 more
TL;DR: The results suggest that litter placement can strongly influence the com- position of decomposer communities and that the resulting trophic relationships are important to determining the rates and timing of plant litter decomposition and N dynamics.
Journal ArticleDOI
Photosynthesis controls of rhizosphere respiration and organic matter decomposition
TL;DR: In this article, the effects of shading wheat plants on rhizosphere respiration and root priming of soil organic matter decomposition were investigated by using a natural abundance 13C tracer method and 14C pulse labeling simultaneously.
Journal ArticleDOI
Synthesis and modeling perspectives of rhizosphere priming
Weixin Cheng,Weixin Cheng,William J. Parton,Miquel A. Gonzalez-Meler,Richard P. Phillips,Shinichi Asao,Gordon G. McNickle,Edward R. Brzostek,Julie D. Jastrow +8 more
TL;DR: This work demonstrates that a shift in microbial metabolic response to different substrate inputs from plants is a plausible mechanism leading to positive or negative RPEs and suggests that the RPE may have resulted from an evolutionarily stable mutualistic association between plants and rhizosphere microbes.
Journal ArticleDOI
Rhizosphere Effects on Decomposition
TL;DR: The magnitude of therhizosphere effect ranged from 0% to as high as 383% above the decomposition rate in the no-plant control, indicating that the rhizosphere priming can substantially intensify decomposition.
Journal ArticleDOI
Rhizosphere priming effects on soil carbon and nitrogen mineralization
Biao Zhu,Biao Zhu,Jessica L. M. Gutknecht,Jessica L. M. Gutknecht,Donald J. Herman,Daniel C. Keck,Daniel C. Keck,Mary K. Firestone,Weixin Cheng +8 more
TL;DR: Investigating the RPE of two plant species grown in two soil types and sampled at two phenological stages over an 88-day period shows that root–soil–microbial interactions can stimulate soil C and N mineralization through rhizosphere effects, providing clear evidence for the microbial activation hypothesis of RPE.
