Biochar addition to soil has also been reported to alter soil microbial community structure, and to both stimulate and retard the decomposition of native soil organic matter (SOM). We conducted a short-term incubation experiment using two (13)C-labelled biochars produced from wheat or eucalypt shoots, which were incorporated in an aridic arenosol to examine the fate of the labile fraction of biochar-C through the microbial community. This was achieved using compound specific isotopic analysis (CSIA) of phospholipid fatty acids (PLFAs). A proportion of the biologically-available fraction of both biochars was rapidly (within three days) utilised by gram positive bacteria. There was a sharp peak in CO2 evolution shortly after biochar addition, resulting from rapid turnover of labile C components in biochars and through positive priming of native SOM. Our results demonstrate that this CO2 evolution was at least partially microbially mediated, and that biochar application to soil can cause significant and rapid changes in the soil microbial community; likely due to addition of labile C and increases in soil pH.", "keywords": ["Carbon sequestration", "[SDE] Environmental Sciences", "Carbon Sequestration", "Chromatography", " Gas", "Magnetic Resonance Spectroscopy", "550", "short term", "[SDV]Life Sciences [q-bio]", "growth", "black carbon", "Char", "01 natural sciences", "630", "Mass Spectrometry", "c 13 plfa", "Black carbon", "soil organic matter", "Soil Pollutants", "mineralization", "Organic carbon", "Phospholipids", "Soil Microbiology", "char", "0105 earth and related environmental sciences", "2.

This field experiment is located in the east of Vienna in a Pannonian climate and it was started in 1988. The methodological approach included elemental analyses, FT-IR, 13C NMR and fluorimetric measurements. Both MT and RT revealed significant depth gradients of yields of extractable HAs. In CT no depth gradient was observable, neither for HA yields nor for observed molecular characteristics. This indicated a destruction of the gradient by mixing of the soil in CT. Especially MT showed an increase of aromatic moieties with depth, suggesting an increased humification of HAs in the lower soil layers. Gradients with similar trends were indicated for the carbonylic, the amidic and probably the hydroxylic groups in HAs extracted from MT and RT samples. The data revealed with FT-IR and solid-state 13C NMR spectroscopy were convincing, plausible and meaningful, the highly sensitive fluorescence spectroscopy was limited because of strong quenching by inner filter effects, compromising data reliability. However, the fluorescence results based on a defined HAs concentration (and comparing soils from the same site) were in line with results from the other methods (13C NMR and FT-IR). As a consequence, the influence of tillage treatments can be followed by absence or presence of depth gradients of the according molecular characteristics in extracted HAs.", "keywords": ["Magnetic Resonance Spectroscopy", "Agriculture", "04 agricultural and veterinary sciences", "15.

However, tillage can have marked effects on soil properties, specifically nutrient redistribution or stratification in the soil profile. The objective of this research was to examine soil phosphorus (P) forms and concentrations in a long\uffe2\uff80\uff90term study comparing conservation tillage (direct drilling, \uffe2\uff80\uff9cNo Till\uffe2\uff80\uff9d) and conventional tillage (moldboard plowing to 20 cm depth, \uffe2\uff80\uff9cTill\uffe2\uff80\uff9d) established on a fine sandy loam (Orthic Humo\uffe2\uff80\uff90Ferric Podzol) in Prince Edward Island, Canada. No significant differences in total carbon (C), total nitrogen (N), total P, or total organic P concentrations were detected between the tillage systems at any depth in the 0\uffe2\uff80\uff90 to 60\uffe2\uff80\uff90cm depth range analyzed. However, analysis with phosphorus\uffe2\uff80\uff9031 nuclear magnetic resonance spectroscopy showed differences in P forms in the plow layer. In particular, the concentration of orthophosphate was significantly higher under No Till than Till at 5 to 10 cm, but the reverse was true at 10 to 20 cm. Mehlich 3\uffe2\uff80\uff93extractable P was also significantly higher in No Till at 5 to 10 cm and significantly higher in Till at 20 to 30 cm. This P stratification appears to be caused by a lack of mixing of applied fertilizer in No Till because the same trends were observed for pH and Mehlich 3\uffe2\uff80\uff93extractable Ca (significantly higher in the Till treatment at 20 to 30 cm), reflecting mixing of applied lime. The P saturation ratio was significantly higher under No Till at 0 to 5 cm and exceeded the recommended limits, suggesting that P stratification under No Till had increased the potential for P loss in runoff from these sites.</p>", "keywords": ["Conservation of Natural Resources", "Soil", "Magnetic Resonance Spectroscopy", "13.
