“…These observations are in agreement with those of Wu et al (2000), who reported alkaline pH for composts made with sludge and garden residues. Many other authors reported no effect on pH (Bevacqua and Mellano, 1994;Crecchio et al, 2001;Zebarth et al, 1999). However, there are several studies that revealed either an increase of acidic soil (Hue, 1992;Whalen et al, 2000;Baziramakenga et al, 2001;Butler and Muir, 2006;Valarini et al, 2009) or a decrease (Chang et al, 1991), While increasing pH is clearly valuable in terms of improving microelement availability, lowering pH should be limited to avoid enhancing the solubility of toxic elements.…”

A B S T R A C TThe objective of this study was to determine the effects of the application of different doses of compost made with sludge and organic residues from plants on some soil characteristics, growth and yield of sugar beet (Beta vulgaris L.) grown in Moroccan soil having low organic matter. A field experiment was conducted and complete randomized block with four replicates was designed. Treatments consisted of control without any organic amendment and three concentrations of compost (2.5, 5.0 and 7.5 t haG 1 ). Results showed that, in general, application of at least 5 t haG 1 of compost increased soil organic matter along with C rates and other mineral nutrients such as N, P and K. Application of 5 t haG 1 of compost significantly increased sugar beet biomass and recoverable sugar yield. This beneficial effect was reversed with the highest dose of 7.5 t haG 1 .

“…80N samples and SSC+80N samples clustered separately, indicating a stronger influence of these treatments on fungal community. An explanation may be that OWC+80N is (despite the nitrogen fertiliser content) a substrate similar to natural organic carbon sources (Crecchio et al 2001;Pérez-Piqueres et al 2005), whilst mineral fertiliser alone or SSC+80N are different from common organic matter sources and thus to a larger degree affect the microbial community structure (Tilman 1998;Pascual et al 1997;Six et al 1999;Kandeler et al 2000). This may be linked to a slower nutrient release compared to mineral fertiliser and sewage sludge compost 80N).…”

“…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.…”

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.

“…As indicated in Table C.5, the C:N ratios calculated on WBF-derived compost varied between 14.4 and 15.2 which was consistent with the results reported by Dimambro et al (2006). The C:N ratio assumed for cardboard-derived compost in home-composting scenarios appeared above the C:N range found in previous literatures (10-40) (Varank et al, 2009, Dimambro et al, 2006, Brito, 2001, Crecchio et al, 2001, Eriksen et al, 1999. …”

I also declare that the intellectual content of this thesis is the product of my own work, except to the extent that assistance from others with data collection and modification of process-oriented model DNDC is acknowledged. Miao GuoSep 2010 LCA of Light-weight Eco-compositesAbstract 3 AbstractThe environmental profiles of novel wheat based foam materials were investigated in this thesis using Life Cycle Assessment (LCA) methods. The LCAs were developed using primary data collected from industrial sources combined with new laboratory experiments supplemented with secondary data from publicly available sources.Laboratory research was conducted to obtain important missing data on WBFs for the LCA modelling, including physico-chemical parameters, biodegradability and energy recovery under anaerobic digestion conditions.Contribution analysis suggested that the emissions evolved from the wheat agroecosystem and PVOH production, together with the energy and infrastructure involved in WBF production were the major contributors to the environmental burdens of the WBF life cycle in most impact categories. The atmospheric emissions resulting from WBF degradation at the end-of-life also emerged as another important contributor to environmental impact. Amongst the diverse ‗end-of-life' scenarios examined, AD and home composting were suggested to be the optimum choices for WBF waste treatment. This research discusses two N 2 O modelling approaches and presents a method to expand the system boundary by integrating the process-oriented model DNDC for field emissions into the LCA. Sensitivity analysis suggests that the environmental profiles of agricultural products are influenced substantially by the system boundary definition. LCA of Light-weight Eco-compositesAbstract 4 Furthermore, it suggests that the ‗general rule' in LCA practice by applying an empirical model or a default emission factor (EF) could deliver unreliable LCA findings.This study also evaluated the sensitivity of the LCA results to methodology and data variations and quantified the uncertainties in the LCA outcomes arising from uncertainty in the inventory and data variability. This has led to an increase in confidence in the LCA findings. At the same time it indicates the areas where improvements in data or methods are needed in order for robust conclusions to be drawn and unbiased information to be delivered e.g. the methodological rigidity of characterization models, the IPCC Tier 1 EF uncertainty range.
