“…Although previous work has shown that VOCs are capable of inhibiting and stimulating specific microbial taxa (Stotzky and Schenck 1976;Wheatley 2002;Mackie and Wheatley 1999;Tsuji et al 1990), the presence of litter VOCs to soils did not lead to appreciable changes in the relative abundances of individual bacterial taxa or overall bacterial community composition. We expected to observe soils exposed to litter VOCs to have increased in the relative abundances of specific groups, such as the methylotrophs, which can consume methanol (Tsuji et al 1990), yet such changes were not detected in this study.…”

“…Likewise, VOC production from living plants has been extensively studied and it is well documented that plants represent an important source of chemically reactive VOCs in the atmosphere (Monson and Holland 2003;Kesselmeier and Staudt 1999). There has been far less attention focused on VOC emissions from soil and litter even though they may also represent important terrestrial sources of VOCs (Stotzky and Schenck 1976;Cleveland and Yavitt 1998;Monson 2002;Asensio et al 2007;Leff and Fierer 2008). In particular, VOC emissions from decomposing litter can be significant (Warneke et al 1999;Schade and Crutzen 1999;Leff and Fierer 2008), yet the fate of such VOCs remains ambiguous.…”

“…In particular, bacteria and fungi produce a wide range of VOCs when grown in pure culture (Mackie and Wheatley 1999;Wheatley 2002) and when actively metabolizing organic matter in litter and soil (Stotzky and Schenck 1976;Stahl and Parkin 1996;Mayrhofer et al 2006;Amaral and Knowles 1998;Mackie and Wheatley 1999). Some of the most common types of VOCs emitted from soils and litters include methanol, monoterpenes, alcohols, and ethers (Stotzky and Schenck 1976;Leff and Fierer 2008), but the types and quantities of VOCs released during microbial decomposition are highly variable and influenced by both substrate type (e.g. litter chemistry) (Wheatley et al 1997;Isidorov and Jdanova 2002) and microbial community composition (Stahl and Parkin 1996).…”

Microbial consumption and production of volatile organic compounds at the soil-litter interface

2009

Substantial amounts of volatile organic compounds (VOCs) can be released during decomposition and these compounds can affect atmospheric chemistry, belowground processes, and the structure of microbial communities in litter and soil. However, we have a limited understanding of the types, quantities and ecological impacts of VOCs emitted from litter. Here we used a closed flow-through system and proton transfer reaction mass spectrometry (PTR-MS) to characterize VOC emissions from soil and two litter types (Pinus taeda and Acer rubrum) over a 72-day incubation period. Microbial respiration rates were measured throughout the incubation, and the soils were harvested at the end of the incubation to determine how

“…Along with plant roots, microorganisms have been reported to be a major source of VOCs produced in soils (Stotzky and Schenk 1976;Stahl and Parkin 1996;Mackie and Wheatley 1999;Isidorov and Jdanova 2002;Leff and Fierer 2008;Kai et al 2009;Insam and Seewald 2010). In contrast to this and despite microbial VOC production, plain soil (without plant roots) is reported to be a VOC sink, strongly dependent on soil temperature and moisture (Asensio et al 2007a).…”

Substrate-induced volatile organic compound emissions from compost-amended soils

et al. 2010

The agronomic effects of composts, mineral fertiliser and combinations thereof on chemical, biological and physiological soil properties have been studied in an 18-year field experiment. The present study aimed at tracing treatment effects by evaluating the volatile organic compound (VOC) emission of the differently treated soils: non-amended control, nitrogen fertilisation and composts (produced from organic waste and sewage sludge, respectively) in combination with nitrogen fertiliser. Microbial community structure was determined by denaturing gradient gel electrophoresis (DGGE). Aerobic and anaerobic soil VOC emission was determined after glucose amendment using proton transfer reaction-mass spectrometry (PTR-MS). After inducing VOC production by substrate (glucose) addition and at the same time reducing oxygen availability to impair degradation of the produced VOCs, we were able to differentiate among the treatments. Organic waste compost did not alter the VOC emissions compared to the untreated control, whilst sewage sludge composts and mineral fertilisation showed distinct effects. This differentiation was supported by DGGE analysis of fungal 18S rDNA fragments and confirms earlier findings on bacterial communities. Three major conclusions can be drawn: (1) VOC patterns are able to discriminate among soil treatments.(2) Sewage sludge compost and mineral fertilisation have not only the strongest impact on microbial community composition but also on VOC emission patterns, but specific tracer VOCs could not be identified. (3) Future efforts should aim at a PTR-MS-linked identification of the detected masses.

“…In the few existing studies, the variety of VOCs measured from soils is broad, and many of these compounds are not found in aboveground plant parts. In field studies and natural soil microcosms, numerous soil-originating VOCs have been found, including alcohols, aldehydes, ketones, aromatics, carboxylic acids, esters, ethers, nitriles, sulphides, and aliphatic hydrocarbons, in addition to the most common terpenoids (Stotzky et al 1976, Janson et al 1999, Hayward et al 2001, Isidorov and Jdanova 2002, Hellén et al 2006, Asensio et al 2007a, McNeal and Herbert 2009, Greenberg et al 2012). Measurements of VOCs have traditionally been conducted mainly during growing seasons, when the VOC emissions from plants are highest.…”

Terrestrial ecosystems, mainly plants, emit large amounts of volatile organic compounds (VOCs) into the atmosphere. In addition to plants, VOCs also have less-known sources, such as soil. VOCs are a very diverse group of reactive compounds, including terpenoids, alcohols, aldehydes and ketones. Due to their high reactivity, VOCs take part in chemical reactions in the atmosphere and thus also affect Earth's radiation balance.In this study, chamber and snow gradient techniques for measuring boreal soil and forest floor VOC fluxes were developed. Spatial and temporal variability in fluxes was studied with year-round measurements in the field and the sources of boreal soil VOCs in the laboratory with fungal isolates. Determination of the compounds was performed mass spectrometrically.This study reveals that VOCs from soil are emitted by living roots, above-and belowground litter and microbes. The strongest source appears to be litter, in which both plant residuals and decomposers play a role in the emissions. Temperature and moisture are the most critical physical factors driving VOC fluxes. Since the environment in boreal forests undergoes strong seasonal changes, the VOC flux strength of the forest floor varies markedly during the year, being highest in spring and autumn. The high spatial heterogeneity of the forest floor was also clearly visible in VOC fluxes. The fluxes of trace gases (CO 2 , CH 4 and N 2 O) from soil, which are also related to the soil biological activity and physical conditions, did not correlate with the VOC fluxes.Our results show that emissions of VOCs from the boreal forest floor accounts for as much as several tens of percent, depending on the season, of the total forest ecosystem VOC emissions. This can be utilized in air chemistry models, which are almost entirely lacking the below-canopy compartment.
