Abstract
The use of compost to enhance plant growth and mineral nutrients composition are extensively studied but not much literature information exists on its influence on plant metabolic profiles. A study was performed to assess a 5-year variable frequency of application of Compost Quality Alliance tested municipal solid waste (MSW) compost effect on metabolic profiles of the edible portions of four different vegetable plants. The plants were lettuce (Latuca sativa cv. Grand Rapids), beets (Beta vulgaris cv. Detroit Supreme), carrot (Daucus carota cv. Nantes) and green beans (Phaseolus vulgaris cv. Golden Wax) grown under a sub-humid continental climate. The treatments were annual, biennial and no (control) applications of the MSW compost. Typically, soil fertility highly increased with the annual application of the MSW compost followed by the biennial application but declined in the control plot. The annually applied MSW compost increased total amino acids in the lettuce, carrot, beets, and green beans by ca. 323%, 109%, 94% and 18% respectively, compared to the control. Overall, total phospholipids were enhanced by the biennially applied MSW compost. Total organic acids in the lettuce, beets, and green beans were altered by the annual and biennial MSW compost applications by ca. 35% and 23%; 6% and 6.4%; and 22% and 65%, respectively compared to the control. A 2-dimension principal component analysis biplot confirmed positive association between the different frequencies of MSW compost application and soil fertility enhancement of plant metabolites. In conclusion, the annual application of MSW compost enhanced amino acids, phospholipids, acylcarnitines, amines and choline but reduced glucose in the lettuce, beets, carrot, and green beans. Further studies to elucidate the mechanisms underpinning such biofortification will be required.

Abstract
Land application of composts affects concentration and composition of dissolved organic matter (OM) which plays important roles in soil functioning and may have effects on spreading of environmental pollution. Linking between the composition of bulk compost OM and its water-soluble fraction may, therefore, allow better understanding and prediction of the environmental impact of compost added to soil. The objectives of this study were to (i) examine composition-based links between bulk compost OM and water-extractable OM (WEOM), and (ii) evaluate and quantify selectivity of bulk compost OM dissolution, based on infrared (IR) absorbing functional groups. For that, 8 different composts and their freeze-dried WEOMs were characterized by mid-IR transmission spectroscopy. Compositions of compost OM and of WEOM were characterized in terms of ratios (R) defined on the basis of both areas and heights of specific IR absorbance bands in relation to absorbance by aliphatic CH groups. A simple novel approach is suggested, whereby selective dissolution of compost OM components is quantified by relating the R values determined for WEOM to those associated with compost OM. Significant similarities of IR spectra found in a series of WEOMs (and, to a lesser extent, in a series of compost OMs) suggest significant contributions of OM carboxylic groups to various bands. IR absorbance of compost OM contributed by hydrophilic and, specifically, carboxyl and carboxylate groups, when related to absorbance by aliphatic CH groups, can be used for predicting the indices characterizing WEOM composition, such as IR absorbance-based R values and aromaticity estimated from specific UV absorbance.

Abstract
The Fusarium wilt of date palm caused by Fusarium oxysporum f.sp. albedinis (Foa) is the most damaging disease in Morocco. It has destroyed more than 12 million trees in the country. Until now, there is no efficient approach to manage this disease. However, biocontrol of soil-borne phytopathogens with compost is currently an established horticultural approach. This study aimed to evaluate the effect of compost extracts in the biocontrol of Foa and their mechanism of action and to investigate parameters involved in compost maturity. Maturity (phytotoxicity test), sanitary quality (pathogen indicators) and in vitro suppressive effect of four composts were investigated. Date palm by-products compost produced with forced aeration composting system is not phytotoxic presenting a germination index of 83.78%. In contrast, two commercial composts were phytotoxic. The maturity was negatively correlated with salinity, C/N ratio and total soluble phenols. Concentrations of pathogen indicators were below suggested limits in all composts. The biocontrol test showed that the date palm wastes compost was more effective; from the sixth day of incubation, the unsterilized extract of this compost at 10% showed the highest antagonistic effect against the pathogen with an inhibition rate of 100%. The inhibition rate using microfiltrated extract didn't exceed 30%. All autoclaved extracts lost their antagonistic effect against the indicator fungus. Thus, the suppressive effect is mainly due to the indigenous microorganisms. Findings indicate the relevance of maturity in the evaluation of compost quality and the efficiency of date palm wastes compost in the suppression of Foa.

Abstract
Five grape marc composts prepared by different procedures (composting and vermicompost at several scales) were tested as potential components of plant growth media. The five composts had high organic matter content (>90%), low electric conductivity (<1 dS m(-1)) and a pH between 7 and 8. Different chemical and biochemical analyses performed indicated the higher stability of those composts submitted to a longer composting process or to a vermicomposting process (lower water soluble organic matter, respiration and dehydrogenase activity). In order to determine the suitability of the composts as substrate components, plant growth tests were performed by blending the composts with peat or commercial substrate at two compost rates (25% and 50%). The mixtures were sown with barley (Hordeum vulgare L.) and grown under controlled conditions in an incubation chamber. No prejudicial effects derived from the use of composted grape marc were observed, whatever the procedure of composting used. The results showed that four out of the five composts would be suitable for use in plant growth substrates elaboration, as they did not reduce productivity with respect to the control substrates.

Abstract
In this paper, changes in physico-chemical parameters during trimmings residue composting (cation exchange capacity, germination index, self-heated, NH(4)/NO(3) ratio and C(FA)/C(HA) ratio) in relation to environmental composting parameters (time, aeration, moisture and particle size) of the composting process were studied. A central composite experimental design was used to obtain the polynomial model for each dependent variable. Results of the modelling showed that among the studied range, moisture was the highest influenced parameter in maturity evaluation, with respect to aeration and particle size. An exception was found for CEC evolution. In this parameter, the highest influence was found for particle size. Moreover, a product with acceptable chemical properties entails operating at medium moisture content (55%) and medium-to-high particle size (3-5 cm). Moderate to low aeration (0.2 m(3) air kg(-1) d(-1)) would be the best compromise to composting this residue, due to the scarce statistical influence of this independent variable.

Abstract
The effects of three different mixtures of organic waste on composting in a rotary drum were examined by measuring changes in physico-chemical and biological parameters. It was observed that the time courses of the three mixtures: run A (grass cuttings, vegetable waste and food waste), run B (cattle manure, vegetable waste and sawdust) and run C (cattle manure, food waste, vegetable waste, paper waste and sawdust) were quite diverse. Run B, with initial C/N ratio 22 and containing a large proportion of cattle manure produced high quality and mature compost within 20 days. It showed a final total nitrogen (2.1%), final total phosphorus 3.52 g kg(-1), final total organic carbon (TOC) (24.8%) and final moisture content (44%). At the end of 20 days, higher degradation led to final chemical oxygen demand (COD) (454 mg L(- 1)), biochemical oxygen demand (BOD) (107 mg L(- 1)), fecal coliform (1.2 x 10(2) bacteria g(- 1)), fecal streptococci (85 bacteria g(-1)) and low electrical conductivity (1.658 dS m(-1)), respectively. Furthermore, run C with initial C/N ratio of 30 and containing a larger amount of food and vegetable waste produced good quality compost and resulted in 4.34% total nitrogen and 2.42% total phosphorus after 20 days, but, it had higher final fecal coliform 2.5 x 10(4) bacteria g( -1), fecal streptococci 2.1 x 10(4) bacteria g(-1), high TOC and NH(4)-N and a BOD/COD ratio of 0.63, which rendered it hygienically unsafe and immature. Finally, run A with initial C/N ratio of 15 showed a higher amount of EC (4.84 dS m(-1)), NH(4)-N, BOD/COD ratio of 0.4 with 15% nitrogen loss, which indicated an unstable product even after 20 days of composting. Therefore, it was found that rotary drum composting of a combination of cattle manure, vegetable waste and sawdust resulted in a primary stabilized compost within 20 days of composting.
