“…Secondly, earthworm activity in organic waste life increases the looseness of the pile, which further facilitates the composting process [ 97 ]. Yu et al concentrated earthworms in waste mushroom compost and found that vermicomposting improved ion exchange capacity (139.8%), pH (6.9%) and nitrate (71.1%) as well as reduced total carbon (31.2%) and carbon to nitrogen ratio (32.1%), indicating that earthworm inoculation can promote compost product quality and facilitate compost decay [ 98 ] Gong et al used earthworms to compost corn stalks and found that they could reduce greenhouse gas emissions by 66.23% and 55.12% with vermicomposting [ 99 ]. Therefore, it can be said that vermicomposting is a greener, safer and more economical way of treatment.…”

“…5 Vermicomposting is a bio-oxidative process of decomposing organic matter by the combined action of earthworm and micro-organisms. 6 Micro-organisms of earthworm's gut and substrate material both act to degrade substance. 7 Earthworms act as mechanical blender and its gut act as bio reactor in which substrate aeration, mixing, grinding, fragmentation, enzymatic digestion and microbial decomposition take place.…”

A six‐week study was conducted on vermicomposting of textile sludge spiked with cow dung at a dry mass ratio of 2:3 by epigeic earthworm Eisenia fetida, with variable population densities (40, 80, and 120 earthworm/kg dry substrate). The earthworm characteristics and metal content of the substrate were observed at the beginning and the end of the experiment, whereas particle size, pH, electrical conductivity (EC), volatile matter (VM), total organic carbon (TOC), and total Kjeldhal nitrogen (TKN) were determined at every week. No mortality of E. fetida was found during the composting process. A high rate of cocoon or egg production (~4 cocoon earthworm−1) was evident in the most populated substrate. However, overcrowding affected the production of hatchlings, resulting in 5.57–1.03 hatchling earthworm−1 from the lowest to the highest population densities. Growth of the adult earthworm was also retarded, which varied from 0.44 to 0.35 g earthworm−1 with the increase of population density due to high competition for food. The particle size of the substrate material was reduced from 4 mm to 0.6 mm in the most populated substrate which was ascertained to be the most efficient option to reduce substrate particle size. All final substrates gained a C/N ratio lower than 20 except the lowest populated substrate. The change in metallic contents incorporated in substrates showed reverse relationship with the population. Though the overall result demonstrated that the physicochemical properties of the substrate materials are favored by the higher population density, it showed negative effect on the biological activities of earthworms.

“…Many researches paid attention on response of crop to vermicompost application (Carnimeo et al, 2022; López et al, 2021; Yu et al, 2022). The promoting effect of vermicompost application on crops is partly due to keeping humus organic matter and mineral nutrients, as well as containing amino acids, indoleacetic acid, digestive enzymes, numerous and diverse microorganisms, disease‐resistant strains, and other beneficial substances (Wang et al, 2018).…”

The utilization of agricultural waste organic materials through composting technology has gained significant traction in agricultural production as an effective means of crop nutrient management. However, the differences in the impact of organic amendments prepared by traditional composting and vermicomposting on soil properties still deserve further research. Based on field experiments conducted in greenhouse, compared to chemical fertilizer treatments as control, we utilized traditional compost (OF) and vermicompost (VcF) derived from agricultural organic waste edible mushroom bran and cow manure (2:8). Variations in soil physiochemical properties, activities of soil enzymes related C and P cycling, abundances and diversities of bacterial 16S rRNA and fungal ITS gene at total DNA level were analyzed. Both compost treatments enhanced soil organic carbon, soil total phosphorus, and soil available P content significantly and also increased the activities of soil α‐glucosidase, β‐glucosidase, acid phosphomonoesterase, and alkaline phosphomonoesterase significantly. The above results suggested that soil C and P transformations were stimulated effectively by both organic amendments. OF and VcF increased the fungal ITS absolute abundances significantly while diversity indices of soil bacterial community increased significantly under both treatments. Correlation analysis indicated that bacterial community composition was strongly correlated with several soil property indexes while fungal community composition was only significantly correlated with soil total phosphorous content. In conclusion, similar to traditional compost, vermicompost significantly improved soil nutrient cycling (especially C and P aspects). In terms of soil microbes, bacteria and fungi showed different responding mechanism to vermicompost: bacteria adjust microbial structure, while fungi tend to proliferated. In consideration of the advantages of vermicompost in technology and economic cost, it could be applied in the subsequent agricultural production more frequently.
