“…Increase in TCa content may be credited to the mineralization of waste in by worms during vermicomposting. Roca-Pérez et al (2009) have reported that loss of organic matter by degradation, evaporation and volatilization also contributes to increased quantities of the minerals.…”

Purpose Parthenium hysterophorus is one among the most troublesome weeds at the global level. It is mainly controlled by chemical methods. The scientific community is in search of new but non-destructive approaches for its management. Vermicomposting is one among the promising technologies for the management of organic fraction of solid wastes. This study was undertaken to assess the vermicomposting of parthenium weed mixed with biogas plant slurry under laboratory conditions. Method Six different combinations of biogas plant slurry and parthenium were fed to worms in vermibins under controlled laboratory conditions for 60 days. Various physico-chemical parameters before and after vermicomposting were evaluated. Worm biomass production was also monitored periodically during the experimentation period. Results The EC, TCa and NPK content increased significantly after vermicomposting, accompanied by substantial reduction in organic carbon content. C: N ratio was reduced to less than 20. Heavy metals (Fe, Zn, Ni, Cu, Cr and Pb) concentration was higher in vermicompost than in initial waste mixtures. Parthenium weed addition to worm feed was not supportive to the worm growth and fecundity.It was inferred from the results that vermicomposting may be an efficient biological approach to convert partheniumspiked biogas plant slurry into nutrient-rich manure.

“…Accordingly, composted residue return increases the growth rate, stimulates plant performances and enhances the yield and quality of crops (Abdelhamid et al, 2004;Tejada and Gonzalez, 2006;Roca-Pérez et al, 2009 . Furthermore, the rational utilization of pineapple residue resources is becoming an inevitable requirement for the sustainable development of agriculture and the economy.…”

“…There were certain amount of carbohydrate, N, P, K, and other nutrients in residues, the compost applied to soil was transferred to organic matter and enhanced the soil fertility level (Zayed and Abdel-Motaalet, 2005;Benito et al, 2006;Ribeiro et al, 2007;Roca-Pérez et al, 2009). Due to the increase in the organic matter content and improvement of the physical-chemical properties, residue returned as compost supplies a better soil environment and an abundant carbohydrate and nitrogen source that benefits the growth of beneficial microorganisms (Zayed and Abdel-Motaalet, 2005;Ros et al, 2006;Bougnom et al, 2010).…”

Abstract:A field experiment was conducted to investigate the influence of composted pineapple residue return (CPRR) on soil bio-chemical properties and the growth performance of next-cropped pineapple plants. The results suggested that CPRR markedly decreased the soil bulk density and increased the contents of available P and K. CPRR significantly increased the abundance of bacteria and actinomycetes, and the activities of catalase, acid phosphatase and invertase in the soil were notably heightened. Growth characteristics, including the plant height, length of leaves and roots, leaf width, number of leaves and fresh weight of the aboveground and belowground parts were significantly increased by CPRR. The contents of chlorophyll, soluble sugars, and soluble protein, as well root vigor were also markedly increased. CPRR also increased the fruit transverse and longitudinal diameters, weight and yield of next-cropped pineapple.

“…The trace compounds in gaseous emissions were analyzed by a gas chromatography-mass spectrometer (GC-MS) system (Agilent 7890A-5975C, Agilent Technologies, Inc., USA). The germination test was carried out and the germination index was calculated according to the method reported by Roca-Pérez et al (2009). The temperatures and pH were monitored routinely.…”

To reveal potential impacts to environment and human health quantitatively, co-composting and utilization of sludge and woodchips were investigated using a life-cycle-based model, EASETECH.Three scenarios were assessed through experiments using different material ratios. Emission amounts during co-composting were determined by monitoring data and mass balance. With 100 t sludge treatment, co-composting showed impacts to acidification (29.9 PE) and terrestrial eutrophication (57.7 PE) mainly for ammonia emission. Compost utilization presented savings on freshwater eutrophication (-1.5 PE) because of phosphorus substitution. With the application of fewer woodchips, impacts to acidification and terrestrial eutrophication decreased because more ammonium was reserved rather than released. All impacts to human toxicity were not significant (8.2±0.6 PE) because the compost was used for urban landscaping rather than farming. Trace gaseous compounds showed marginal impacts to global warming and toxicity categories. The results provide a new perspective and offer evidence for appropriate sludge treatment selection.
