Large losses of ammonium-nitrogen from a rice ecosystem under elevated CO2

SCIENCE ADVANCES, 6(42).

By: C. Xu *, K. Zhang *, W. Zhu*, J. Xiao *, C. Zhu *, N. Zhang *, F. Yu *, S. Li* ...

TL;DR: It is demonstrated that elevated CO2 causes substantial losses of ammonium-nitrogen that result from anaerobic oxidation of ammonia coupled to reduction of iron, and a new autotrophic member of the bacterial order Burkholderiales is identified that may use soil CO2 as a carbon source to couple an aerobic ammonium oxidation and iron reduction.

2012 journal article

Arbuscular Mycorrhizal Fungi Increase Organic Carbon Decomposition Under Elevated CO2

SCIENCE, 337(6098), 1084–1087.

By: L. Cheng n, F. Booker n, C. Tu n, K. Burkey  n, L. Zhou n, H. Shew  n, T. Rufty  n, S. Hu n 

MeSH headings : Carbon / metabolism; Carbon Dioxide / metabolism; Mycorrhizae / metabolism; Nitrogen / metabolism; Plant Development; Plants / microbiology; Soil Microbiology
TL;DR: Evidence is presented from four independent microcosm and field experiments demonstrating that CO2 enhancement of AMF results in considerable soil carbon losses, challenging the assumption that AMF protect against degradation of organic carbon in soil and raising questions about the current prediction of terrestrial ecosystem carbon balance under future climate-change scenarios.

SOIL MICROBIAL RESPONSES TO ELEVATED CO2 AND O-3 IN A NITROGEN-AGGRADING AGROECOSYSTEM

CARBON CAPTURE AND STORAGE: CO2 MANAGEMENT TECHNOLOGIES, Vol. 6, pp. 277–307.

By: L. Cheng n, F. Booker n, K. Burkey n, C. Tu n, H. Shew  n, T. Rufty  n, E. Fiscus n, J. Deforest *, S. Hu n 

MeSH headings : Aerobiosis / drug effects; Agriculture; Bacteria / drug effects; Biomass; Carbon / metabolism; Carbon Dioxide / pharmacology; Ecosystem; Fatty Acids / analysis; Fungi / drug effects; Minerals / metabolism; Nitrogen / metabolism; Nitrogen Fixation / drug effects; Ozone / pharmacology; Phospholipids / analysis; Seasons; Soil; Soil Microbiology; Soybeans / drug effects; Soybeans / physiology
TL;DR: The results suggest that more attention should be directed towards assessing the impact of N availability on microbial activities and decomposition in projections of soil organic C balance in N-rich systems under future CO2 scenarios. (via Semantic Scholar)

Atmospheric CO2 enrichment facilitates cation release from soil

ECOLOGY LETTERS, 13(3), 284–291.

By: L. Cheng n, J. Zhu*, G. Chen*, X. Zheng *, N. Oh *, T. Rufty  n, D. Richter*, S. Hu n 

author keywords: Anaerobic reduction; cation exchange; dissolved organic carbon; free-air CO2 enrichment; methane; microbial activities; nutrient cations; rice; soil acidification
MeSH headings : Anaerobiosis; Atmosphere / chemistry; Carbon Dioxide / chemistry; Carbon Dioxide / metabolism; Carbon Dioxide / pharmacology; Cations / chemistry; Cell Respiration; Oryza / drug effects; Oryza / growth & development; Oryza / metabolism; Plant Roots / drug effects; Plant Roots / growth & development; Plant Roots / metabolism; Soil; Soil Microbiology
TL;DR: Evidence for a novel mechanism of CO(2)-enhancement of cation release from soil in rice agricultural systems is presented and results indicate that over the short term, elevatedCO(2) may stimulate cationRelease from soil and enhance plant growth. (via Semantic Scholar)
