In this paper, we evaluate the effect of continuous tillage and tillage conversion of NT to FIT and vice versa on SOC and SON stocks, in a long-term experiment at Boigneville in Northern France. Continuous NT (CNT) and FIT (CFIT) treatments were established in 1991 and maintained until 2011 while half of the plots were converted in 2005: from CNT to new FIT (NFIT) and CFIT to new NT (NNT). Bulk densities and organic C and N contents were determined in 2001 and 2011 down to the old ploughing depth (opd) which was also measured. SOC and SON stocks were calculated at equivalent soil mass by correcting either bulk densities or the opd. Both methods produced very close results and similar conclusions. A typical gradient of SOC and SON concentrations vs depth was observed in CNT as opposed to a rather uniform distribution in CFIT. CNT resulted in SOC concentration in the top soil (0-5 cm) higher by 38% in 2001 and 53% in 2011 compared to CFIT. Conversely, it led to a SOC reduction in the deeper layer (ca. 10-28 cm) by 14% in 2001 and 18% in 2011. The global effect was no significant change in SOC and SON stocks between treatments over the old ploughed layer (4060 t soil ha(-1)) in both years: 43.2 and 45.0 t C ha(-1) in 2001 and 44.7 and 45.8 t C ha(-1) in 2011, in CNT and CFIT, respectively. In 2011, six years after tillage conversion, the stratification of SOC and SON had disappeared in NFIT whereas a new one had appeared in NNT with a smaller gradient than in CNT. SOC or SON stocks over the old ploughed layer did not differ significantly between treatments after 6 years of conversion: SOC stocks were 45.8, 43.2, 44.7 and 43.1 t C ha(-1) in the CFIT, NFIT, CNT and NNT treatments, respectively. Furthermore, SOC stocks below the old ploughed layer (ca. 28-40 cm) were slightly greater in FIT than in NT treatment (10.9 vs 8.7 t C ha(-1)). In this experiment, continuous or conversion tillage did not result in any C sequestration benefit. (c) 2013 Elsevier B.V.

This study examines whether plant material produced under elevated CO2 decomposes differently from plant material produced under ambient CO2. Moreover, a long\uffe2\uff80\uff90term experiment offered a unique opportunity to evaluate assumptions about C cycling under elevated CO2 made in coupled climate\uffe2\uff80\uff93soil organic matter (SOM) models. Trifolium repens and Lolium perenne plant materials, produced under elevated (60\uffe2\uff80\uff83Pa) and ambient CO2 at two levels of N fertilizer (140 vs. 560\uffe2\uff80\uff83kg\uffe2\uff80\uff83ha\uffe2\uff88\uff921\uffe2\uff80\uff83yr\uffe2\uff88\uff921), were incubated in soil for 90 days. Soils and plant materials used for the incubation had been exposed to ambient and elevated CO2 under free air carbon dioxide enrichment conditions and had received the N fertilizer for 9 years. The rate of decomposition of L. perenne and T. repens plant materials was unaffected by elevated atmospheric CO2 and rate of N fertilization. Increases in L. perenne plant material C\uffe2\uff80\uff83:\uffe2\uff80\uff83N ratio under elevated CO2 did not affect decomposition rates of the plant material. If under prolonged elevated CO2 changes in soil microbial dynamics had occurred, they were not reflected in the rate of decomposition of the plant material. Only soil respiration under L. perenne, with or without incorporation of plant material, from the low\uffe2\uff80\uff90N fertilization treatment was enhanced after exposure to elevated CO2. This increase in soil respiration was not reflected in an increase in the microbial biomass of the L. perenne soil. The contribution of old and newly sequestered C to soil respiration, as revealed by the 13C\uffe2\uff80\uff90CO2 signature, reflected the turnover times of SOM\uffe2\uff80\uff93C pools as described by multipool SOM models. The results do not confirm the assumption of a negative feedback induced in the C cycle following an increase in CO2, as used in coupled climate\uffe2\uff80\uff93SOM models. Moreover, this study showed no evidence for a positive feedback in the C cycle following additional N fertilization.</p>", "keywords": ["2.

For the past decade, observations of carbonyl sulfide (OCS or COS) have been investigated as a\uffc2\uffa0proxy for carbon uptake by plants. OCS is destroyed by enzymes that interact with CO2 during photosynthesis, namely carbonic anhydrase (CA) and RuBisCO, where CA is the more important one. The majority of sources of OCS to the atmosphere are geographically separated from this large plant sink, whereas the sources and sinks of CO2 are co-located in ecosystems. The drawdown of OCS can therefore be related to the uptake of CO2 without the added complication of co-located emissions comparable in magnitude. Here we review the state of our understanding of the global OCS cycle and its applications to ecosystem carbon cycle science. OCS uptake is correlated well to plant carbon uptake, especially at the regional scale. OCS can be used in conjunction with other independent measures of ecosystem function, like solar-induced fluorescence and carbon and water isotope studies. More work needs to be done to generate global coverage for OCS observations and to link this powerful atmospheric tracer to systems where fundamental questions concerning the carbon and water cycle remain.                     </p>", "keywords": ["570", "550", "GLOBAL BIOGEOCHEMICAL CYCLE", "isotope du carbone", "01 natural sciences", "[PHYS.PHYS.PHYS-AO-PH] Physics [physics]/Physics [physics]/Atmospheric and Oceanic Physics [physics.ao-ph]", "ANTHROPOGENIC EMISSIONS INVENTORY", "Life", "[SDU.STU.GC]Sciences of the Universe [physics]/Earth Sciences/Geochemistry", "QH501-531", "[SDU.STU.GC] Sciences of the Universe [physics]/Earth Sciences/Geochemistry", "Meteorology & Atmospheric Sciences", "REDUCED SULFUR GASES", "OH-INITIATED OXIDATION", "photosynth\u00e8se", "anhydrase carbonique", "QUANTUM CASCADE LASER", "SOUTHERN GREAT-PLAINS", "ORGANIC VOLATILE SULFUR", "QH540-549.5", "0105 earth and related environmental sciences", "[PHYS.PHYS.PHYS-AO-PH]Physics [physics]/Physics [physics]/Atmospheric and Oceanic Physics [physics.ao-ph]", "QE1-996.5", "Ecology", "FT-IR PRODUCT", "GROSS PRIMARY PRODUCTION", "Geology", "Biological Sciences", "15.
