“…This is higher than with other studies showing that fungi and fungal-feeding organisms are often reduced when soil N fertility and recycling increases (Coleman et al 1983;Bardgett et al 1999;De Vries et al 2006, 2007Lauber et al 2008;Krumins et al 2009). The mechanism is unknown but both are direct effects of fertilizer itself, and changes in the plant community and litter associated with fertilizers could be involved (Donnison et al 2000;Manning et al 2006).…”

“…Landuse-conversion-induced changes in soil microbial community were also related to soil pH and NH 4 þ -N content. A previous study also concluded that soil pH and nutrient status, not specifically land-use type, could best predict shifts in microbial community composition [21]. We found that soil pH significantly decreased after 2 years of conversion from the rice paddies to vegetable fields.…”

“…Yang et al [20] found that total phospholipid fatty acids (PLFAs) decreased significantly after land-use change from paddy to orchard, and soil moisture, organic matter, and nitrogen (N) were found to be the most important environmental factors affecting the variations in microbial community structure. Soil pH is another important factor that regulates soil microbial communities [21,22]. In the process of land-use conversion from paddy to upland, pH was one of the most important factors affecting soil microbial community structure [20].…”

a b s t r a c tA short-term experiment was carried out in southern China to investigate the effects of land-use conversion from rice paddies to vegetable fields and fertilization on soil microbial community structure by analyzing soil phospholipid fatty acid (PLFA) profiles. A split-plot design with four replicates was adopted, in which land use (paddy and vegetable field) was the first-level treatment and fertilization (conventional fertilization and no fertilization) was nested as the second level. Our results showed that both land-use conversion and fertilization had significant effects on microbial community structure. After 2 years of land-use conversion, the total amount of PLFAs were 3.54 and 2.97 nmol g À1 for fertilized (VeF) and unfertilized (VeNF) vegetable fields, respectively, and 3.19 and 2.32 nmol g À1 for fertilized (R eF) and unfertilized (ReNF) rice paddies, respectively. Soil fungal PLFAs were 1.04 and 0.87 nmol g À1 for VeF and VeNF, respectively, which were significantly increased by 13.9 and 11.4 times compared with those of ReF and ReNF, respectively. The ratio of fungal to bacterial PLFAs significantly increased in vegetable fields compared with rice paddies. No significant differences were found in the total, bacterial, and actinomycetic PLFAs between vegetable fields and rice paddies. The application of fertilizer significantly increased the amount of total PLFAs and bacterial PLFAs. With land-use conversion and fertilization, soil physicochemical properties also changed, and microbial community structure showed a significant relationship with soil water content, NH 4 þ -N, and pH, which explained the land-use conversion and fertilization effects on soil microbial community composition.

“…The soil is a loamy sand with a pH of 3.6 and an organic carbon concentration of 9 g C kg -1 . Additional details on soil edaphic factors can be found in Lauber et al (2008). After collection, soil was sieved to 2 mm, homogenized, and shipped to the University of Colorado where it was stored at 4°C.…”

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

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
