“…More than 100 years since, vermicomposting technology is now being recognized as a sustainable, inexpensive and environmentally friendly approach to recycling organic waste. The final product of this technology offers more available nutrients and diversity microbial populations than those of normal composting (Frederickson et al 1997, Edwards et al 1988, and is considered an environmentally friendly organic fertilizer for agricultural application (Tajbakhsh et al 2010). Previous studies have demonstrated that this technology can convert agricultural waste such as vegetables or fruits into useful compost (Mainoo et al 2009, Fernández-Gómez et al 2010a, Fernández-Gómez et al 2010b, Suthar et al 2009.…”

Vermicomposting technology is an environmentally friendly, sustainable, and low-cost tool used to convert agronomical and food waste into manure, facilitated by the decomposition and digestion by earthworms. In this study, we evaluated the chemical properties and microbial diversity of vermicompost (VC) derived from school lunch waste, which has long been a serious problem in many countries including Japan. The results revealed that 18-week-old VC promoted the root elongation of plants, and also showed a higher germination index (GI) and higher cation exchange capacity (CEC), indicating that vermicompost made from school food waste is an acceptable manure. As a result of the microbiome analysis by the sequencing of 16S ribosomal DNA (rDNA) using next generation sequencing (NGS), higher ratios of Bacillus, Pseudomonas, and Paenibacillus species, which may include beneficial bacteria for plant growth, were detected in VC than in the control compost (CC). These results demonstrate the significance of vermicompost in utilizing waste from school lunch, suggesting the possibility of implementing a waste recycling system that leads to reducing and recycling food waste in schools.

“…Since the bamboo and kudzu are characterized by rich carbon and nitrogen, respectively (Wang et al, 2013;Nakhshiniev et al, 2014), their combination is ideal as a feed stock for vermicomposting. Vermicomposting is a nutrient recycling process for biodegradable solid wastes through the decomposition Effects of vermicompost water extract prepared from bamboo and kudzu against Meloidogyne incognita and digestion of earthworms and its associated microorganisms (Elvira et al, 1998;Tajbakhsh et al, 2011). Generally, a minimum of two months are needed to produce vermicompost suitable to be used as organic fertilizer (Radovich and Arancon, 2011).…”

A series of experiments in laboratory, greenhouse, and field were conducted to compare the nematode suppressive effect of vermicompost tea (VCT) prepared from vermicompost with mosobamboo (Phyllostachys edulis (Carrière) J. Houz.) and kudzu (Pueraria lobata (Willd) Ohwi) as feed stock (weed VCT) to that prepared from vegetable food waste (vegetable VCT) against Meloidogyne incognita and Rotylenchulus reniformis. Two laboratory trials were conducted by incubating eggs of M. incognita and R. reniformis in weed VCT or vegetable VCT over 1 wk. These trials revealed that although both VCTs suppressed M. incognita egg hatching compared to water control, only weed VCT suppressed R. reniformis egg hatching. In addition, both VCTs suppressed the mobility of second stage juveniles (J2s) of M. incognita equally compared to water control though suppression from weed VCT performed inconsistently between the trials. When root penetration of M. incognita on cucumber drenched with VCT on one side of a split-root system in a greenhouse sterile sand-soil mix was examined, weed VCT suppressed root penetration of M. incognita on the other side of the root in two trials, but vegetable VCT was only effective in one trial. However, both VCTs did not suppress R. reniformis root penetration. When the effect of the VCTs was examined in two cowpea (Vigna unguiculata) field trials, drenching of VCTs did not affect cowpea growth and yield, but weed VCT reduced root-gall index compared to the water control in both trials. Although both VCTs did not reduce the number of M. incognita and R. reniformis in soil, weed VCT did increase omnivorous nematodes in the second trial, indicating a gradual improvement of soil food web structure through VCT drenching over time. Overall, performance of weed VCT was more consistent than vegetable VCT for plant-parasitic nematodes suppression.
