“…How is vermicompost made? Vermicompost is formed through the process of converting organic materials into humus-like substances called vermicast, which is rich in organic matter and mineral nutrients, and the conversion process is carried out by earthworms and microorganisms [20][21][22]. It has been proven through many studies that vermicompost tea has many positive effects on the growth and productivity of crops, in addition to its ability to control plant diseases [13].…”

Recently, the use of biostimulants as natural and eco-friendly fertilizers has received increasing attention because of their efficiency in terms of improving crops’ qualitative and quantitative parameters, i.e., growth, yield, and chemical composition. We studied the effect of four biostimulants—humic acid (20 g/L), vermicompost tea (15 mL/L), moringa leaf extract (1:30 v/v), and yeast extract (5 g/L), with tap water as a control treatment—on the qualitative and quantitative characteristics of snap beans. The experiment was designed using a complete randomized block with triplicates. The results showed a significant improvement in treated plant performance (growth and yield), chlorophyll, and chemical composition compared to untreated plants. Using moringa leaf extract increased the plant height, number of leaves and branches/plant, and fresh and dry weight. Additionally, the diameter of the treated plant stems and the quality of the crop and pods were also significantly higher than those of plants treated with vermicompost or humic acid extract. It is also noted that the profile of amino acids was improved using all tested biostimulants. This leads to the conclusion that the addition of moringa leaf extract and vermicompost tea not only positively affects the qualitative and quantitative properties of snap bean but is also reflected in its nutritional value as a plant-based food.

“…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). But vermicompost also has obvious improvement effect on soil physiochemical properties (Akinnuoye‐Adelabu et al, 2019; Hebeková et al, 2020; Li, Nie, et al, 2019; Li, Wan, et al, 2019; Shi et al, 2020; Wang et al, 2018). Previous results indicated vermicompost could better promote nutrient mineralization in soil and has greater potential to improve soil nutrition status (Hebeková et al, 2020; Shi et al, 2020) and sustain agricultural development (Han et al, 2021; Zhang et al, 2021).…”

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.

“…Composting is a biological process of controlled aerobic decomposition that transforms organic waste into nutrient-rich and stable organic products [7], which can be used as agricultural fertilizers [8][9][10][11]. This technique is especially interesting in countries, such as Brazil, where agriculture is one of the pillars of the economy, in addition to being highly dependent on the use of synthetic fertilizers.…”

“…Earthworms excrete products that constitute nutritious organic fertilizers, which are rich in humus, stabilized organic matter, macro and micronutrients, bene cial soil microorganisms, and growth hormones [7,15,16]. These substances have proved to be promoters and protectors of various plant crops in pot experiments [8][9][10][11]15]. Furthermore, according to [17], the application of composts (from composted domestic waste) can increase the amount of humidi ed carbon in agricultural soils for four years.…”

The efficiency of millicomposting (M, with millipedes), vermicomposting (V – with earthworms), and traditional composting (C – no invertebrates) of vegetal waste was investigated statistically. Composting took place in closed systems to avoid external interferences during the experiments and allow monitoring of the main physico-chemical parameters. The experiments were replicated six times (n = 6). Quality was assessed via analysis of variance (one-way and Welch procedures) and post-hoc comparisons. Temperature profiles were similar in the three composting types. After 92 days, the compost volume produced in V (51%) decreased more than in M (43%) and C (44%) (p = 0.001). Organic carbon, nitrogen contents, and C/N ratios were also similar (all p > 0.1). Vermicomposting produced humus of higher nutritional quality, whereas M leachates yielded higher nutritional levels and maturity degrees. The Ca content was higher in V and M, while K and Mg were higher in V. pH, Ca, Mg, P2O5, and S contents were higher in V than in C (all p < 0,05). The leachate volumes, electrical conductivity, and Na+ and PO43− contents were similar in the three composting types (p > 0.05). pH, K+ and NH4+ contents were higher while the NO3− was lower in V than in M (all p < 0.005). The only difference observed in C was lower pH when compared to those of V. Although all three composting types were efficient in producing mature, high-quality organic fertilizers, the addition of detritivorous animals improved the composting efficiency and the quality of the final products. This study also attested the potential of millicomposting in producing good-quality liquid fertilizers.
