“…More specifically, earthworms and microorganisms interact in a complex way during the VC process in order to achieve the bio-oxidation and organic matter stabilization [10,11]. Eisenia fetida is one of the best earthworm species for building a VC system in temperate regions mainly due to its resistance for an extensive range of environmental factors such as pH, moisture content, and temperature [12]. By reducing bulk density, earthworm-produced VC can improve the physical qualities of soil such as aggregate stability, total porosity, air and water permeability, and penetration resistance [13].…”

Extensive industrialization, urbanization, and excessive use of chemicals in agricultural practices have caused soil quality depletion and reduced its nutritional value. In this context, the present study aimed to evaluate the effect of vermicompost (VC) on different soil properties such as pH, electrical conductivity, soil organic carbon, soil organic matter, total phosphorus, and bulk density to understand the soil enrichment for different land use patterns i.e., agriculture soil (AS), forest soil (FS) and barren soil (BS). The collected soil samples were mixed with VC in different proportions (1:1, 1:2, 1:3, 1:4, and 1:5) and analyzed in terms of aforementioned parameters. Among the investigated soils, the highest microbial biomass was observed for FS samples and noted in the range of 6 – 8 mg/gm of soil. All the original soils, supplemented samples, and VC were also subjected to plant growth analysis. The soil quality index (SQI) was determined using principal component analysis for selected soil samples and resulted mixtures obtained from soil and various proportions of VC. Among all samples, highest SQI was observed as 0.785 for VC. Overall, the result of the study showed that vermicompost can be a potential substitute of chemical fertilizers, thus improving the soil quality and crop yield.

“…While earthworms feed upon the dung in which parasitic nematodes are undergoing a portion of their life cycle (Bacher et al, 2018; Knight et al, 1992), the net effect is highly uncertain (d'Alexis et al, 2009; Grønvold, 1979, 1987; Molavi et al, 2020; Waghorn et al, 2002; Zazouli et al, 2021). Consumption of dung by earthworms has been suggested to result in direct mortality of nematodes during passage through the gut (d'Alexis et al, 2009; Demetrio et al, 2019; Grønvold, 1987; Ray, 2018; Svendsen et al, 2003; Waghorn et al, 2002), while the impacts of dung translocation are also likely to be negative by moving surviving nematodes deeper within the soil compartment.…”

“…Interactions between earthworms and parasites have also been investigated in relation to manure application and the vermicomposting process, with mixed reports. Earthworm, Eisenia fetida , presence was reported to reduce the abundance of unspeciated parasite eggs following the vermicomposting process (Molavi et al, 2020), while other studies found no significant effect (Zazouli et al, 2021).…”

Gastrointestinal helminth parasites undergo part of their life cycle outside their host, such that developmental stages interact with the soil and dung fauna. These interactions are capable of affecting parasite transmission on pastures yet are generally ignored in current models, empirical studies and practical management. Dominant methods of parasite control, which rely on anthelmintic medications for livestock, are becoming increasingly ineffective due to the emergence of drug‐resistant parasite populations. Furthermore, consumer and regulatory pressure on decreased chemical use in agriculture and the consequential disruption of biological processes in the dung through nontarget effects exacerbates issues with anthelmintic reliance. This presents a need for the application and enhancement of nature‐based solutions and biocontrol methods. However, successfully harnessing these options relies on advanced understanding of the ecological system and interacting effects among biotic factors and with immature parasite stages. Here, we develop a framework linking three key groups of dung and soil fauna—fungi, earthworms, and dung beetles—with each other and developmental stages of helminths parasitic in farmed cattle, sheep, and goats in temperate grazing systems. We populate this framework from existing published studies and highlight the interplay between faunal groups and documented ecological outcomes. Of 1756 papers addressing abiotic drivers of populations of these organisms and helminth parasites, only 112 considered interactions between taxa and 36 presented data on interactions between more than two taxonomic groups. Results suggest that fungi reduce parasite abundance and earthworms may enhance fungal communities, while competition between dung taxa may reduce their individual effect on parasite transmission. Dung beetles were found to impact fungal populations and parasite transmission variably, possibly tied to the prevailing climate within a specific ecological context. By exploring combinations of biotic factors, we consider how interactions between species may be fundamental to the ecological consequences of biocontrol strategies and nontarget impacts of anthelmintics on dung and soil fauna and how pasture management alterations to promote invertebrates might help limit parasite transmission. With further development and parameterization the framework could be applied quantitatively to guide, prioritize, and interpret hypothesis‐driven experiments and integrate biotic factors into established models of parasite transmission dynamics.

Dog feces are a known source of nutrient, pathogen, and plastic pollution that can harm human and ecosystem health. Home composting may be a more environmentally sustainable method of managing dog feces and reducing this pollution. While composting is an established method for recycling animal manures into low‐risk soil conditioners for food production, few studies have investigated whether household‐scale compost methods can safely and effectively process dog feces for use in backyard edible gardens. A broad range of literature on in situ composting of dog feces is evaluated and compared according to scale, parameters tested, and compost methods used. Studies are analyzed based on key identified knowledge gaps: appropriate compost technologies to produce quality soil conditioner on small scales, potential for fecal pathogen disinfection in mesophilic compost conditions, and biodegradation of compostable plastic dog waste bags in home compost systems. This review also discusses how existing methods and quality standards for commercial compost can be adapted to dog fecal home composting. Priorities for future research are investigation of household‐scale aerobic compost methods and potential compost amendments needed to effectively decompose dog feces and compostable plastic dog waste bags to produce a good‐quality, sanitized, beneficial soil conditioner for use in home gardens.
