“…Differences in DGGE fingerprints were due to the occurrence of a few faint bands which were missing in other lanes, again denoting the weak influence of the different treatments. These findings confirm the results of Ros et al (2006b) on the bacterial community structure of the same soil and treatments using 16SSU rDNA DGGE fingerprint analysis and of Innerebner et al (2006) who found differences in ammonia-oxidising bacteria community structure.…”

“…It has been reported earlier that some soil treatments (e.g. municipal organic waste compost) take weaker influence on the composition of soil microbial community structure than edaphic conditions, temperature or soil depth (Crecchio et al 2001;Pérez-Piqueres et al 2005;Innerebner et al 2006;Ros et al 2006a, b). In contrast, the application of sewage sludge compost, consisting of faeces and wastewater-derived substances is an artificial intrusion in the soil ecosystem, supplying soil with unfamiliar compounds and nutrients.…”

“…The site is part of a crop rotation fertilisation experiment (grain maize, summer wheat and winter barley) that was started in 1991 by the Austrian Agency for Health and Food Safety. The soil is a loamy silt with a pH of 6.8 (±0.4), an organic matter content of 1.9% (Ros et al 2006a;Innerebner et al 2006) and a water holding capacity of 0.5 g H 2 O per gram dry soil. Soil characteristics and heavy metal contents are described in Ros et al (2006a).…”

“…Besides this, conversion of organic residues such as sewage sludge, green cut, organic wastes or animal manure into useable composts reduces the amount of waste deposed into landfill sites, thereby improving the cycling of matter. Besides these known benefits, soil compost and fertiliser amendments affect the soil microbial community composition and activity in different ways, as has been shown by Innerebner et al (2006) and Ros et al (2006a, b). Microbiological tools range from conventional cultivation approaches to molecular techniques, each of them with its own advantages, biases and limitations.…”

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

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.

“…These practices are: (i) transplanting younger seedlings (ii) using a single seedling per hill, (iii) using wider spacing between hills, (iv) managing water by alternating flooding and draining during vegetative growth, (v) applying compost and (vi) mechanically managing weeds. While several studies based on agronomic and scientific approaches have been conducted (1,9,14) to understand mechanisms responsible for observed increases in rice productivity, the reasons are still unclear. SRI practices are based on careful water management leading to changes in the oxidation states and form of essential nutrients in soil, the cycle of which is mediated by soil organisms (2), are likely.…”

Changes in Bacterial Community Composition in the System of Rice Intensification (SRI) in Chiang Mai, Thailand

et al. 2010

The factors of alternating flooding and draining during the vegetative growth phase and applying compost to investigate changes in bacterial community composition between the system of rice intensification (SRI) and conventionally managed rice were investigated. 16S rRNA gene T-RFLP analysis showed the major changes in the bacterial communities from the beginning of cultivation to vegetative phase, at which time the groups formed remained consistent until the end of cropping season. Significant and consistent separations of microbial communities between the two systems were revealed. These results suggested that the differences in rice cultivation practice can cause the changes in microbial communities.

BACKGROUND It is necessary to inoculate microbes in the composting of special materials. Biogas residue (BR) is rich in refractory lignocellulose. To improve humification processes of BR composting, composite microorganisms (CMs), with multiple functions, were added to the mixture of BR and animal manure. RESULTS The results indicated that four humification indices (DP, PHA, HR, HI) were all markedly higher in the inoculated compost (0.46, 27.5, 43.34, 11.92) than in the uninoculated compost (0.39, 22.53, 28.56, 6.49) (P < 0.05). The inoculation increased the degree of polycondensation and aromatization, and molecular size, as well as the humification degree of BR compost as determined by fluorescence spectroscopy and fluorescence regional integration analysis of humic acids, fulvic acids and hydrophilic fraction, three chemically isolated fractions. Additionally, the inoculation increased the quantity and diversity of indigenous microorganisms and accelerated their proliferation by adjusting environmental conditions to optimize their growth. CONCLUSION The CMs inoculant is suitable for BR composting and inoculating based on the composition of the composting substrate could enhance composting efficiency and improve compost quality. © 2014 Society of Chemical Industry
