“…Recycling of aquatic weeds can solve disposal issues [8]), and enhances their agronomic value with the building up of earthworms (biomass, hatchlings, and cocoons) [9]. Traditionally, cow manure is regarded as an important resource for sustainable rural agriculture [10,11] and a primary substrate for vermicomposting [12,13]. There has been a rapid increase in cattle farming as a pivotal source of livelihood among Himalayan farmers.…”

There is an immense demand for vermicomposting employing psychrophilic vermiculture (Aporrectodea caliginosa) for management of wastes under the Himalayan ecosystem. Dalweed (weeds from the world-famous urban Dal Lake) and cow manure (CM) are cheaply and abundantly available bio resources in Kashmir valley. Dalweed (DW), disposed of in the heart of the city, ascribes unpleasant effects on tourism and the natural ecosystem. Initial substrate mixtures of DW and CM with different ratios (CM100, DW100, CM80:DW20, CM60:DW40, CM40:DW60 and CM20:DW80) and castings harvested were analyzed for the following parameters: pH, TOC, TN, NO3- P, K, Fe, Zn, C:N, C:P, and C:S ratio. The results of a 56day study revealed in consistency and disparity towards the bio-optimization of coprolites depending upon the type of waste residue and mixture ratio used. Treatments with medium to low dalweed residues (CM60:DW40 followed by CM80:DW20) were found to be optimum and significantly primed chemical properties of castings using A. caligenosa. C:N, C:P, and C:S ratios showed a non-linear response with maximum decrease in C:N ratio by 35%, C:P ratio by 38% in CM100, and C:S ratio by 67% in DW100. Humification ratio, humification index, and percent humic acids were changed across all the treatments with the highest respective values of 21.33 ± 1.05, 11.33 ± 0.76, and 47.83 ± 0.76 for CM60:DW40. Results also showed that the earthworm population and biomass significantly increased with the highest respective increments of 57.53% and 74.88% in CM60:DW40 over initial values. Moreover, the highest number of cocoons (95.67 ± 1.17) were recorded within CM60:DW40 and the lowest in the control (43.33 ± 1.53). Dehydrogenase and fluorescein diacetate activities were inconsistent with the highest in CM40:DW60 (64.64%) and CM20:DW80 (63.54%) respectively over the initial substrates, while highest urease activity (74.40%) was observed from CM100. The results highlight the role of A. caliginosa in sustainable transformation of CM and DW with insightful, beneficial, and priming impacts on castings for its agronomic value.

“…These studies focused on different approaches, which confirmed that the most important aspect of the management of agricultural wastes mainly depends on the nature of agricultural wastes (Khan and Faisal 2020). The agri-wastes could be managed byvermicomposting (Gupta et al 2019;Rini et al 2020), biomethanation (Dar et al 2021), implications for the circular economy (Woodard 2021), using tool of life cycle assessment (Ahamed et al 2021), and the effective transformation (Prasad et al 2020). It is worth to mention that all countries are in a need for a proper management of agri-wastes for the sustainable agriculture (Khan and Faisal, 2020) and the management process of any waste and its choosing should depend on its being minimizing environmental impact and maximum safety (Prasad et al 2020).…”

Agricultural Waste and its Nano-Management: Mini Review

A GRICULTURAL wastes are considered residues resulted during the agricultural production and after harvesting fruit and vegetable and their processing, agro-industrial by/co-products from the grapes, banana, olives and milk processing. These wastes may represent a treasure when they are turning into valuable applications (i.e., composts, biochar, adsorbents for removing pollutants from the environment and organic fertilizers) instead of burning it in open fields causing several environmental problems such as soil degradation and air pollution. The landfill disposal and open dumping of agro-wastes is a common practice in the developing countries generating huge amounts of ash, which may create serious health and environmental problems, primarily due to pollution of groundwater. Under the umbrella of the green bioeconomy and based on industrial innovation and high technology, new and better approaches for the recovery of agricultural wastes have been developed. This has contributed to guaranteeing sustainable production and its consumption, resource utilizing efficiency, the conversation of these wastes into valuable products and the reduction of negative environmental impacts.The common management of Agro-wastes may include a lot of suggested uses such as the production of biosynthesis of nanoparticles, biotechnological products, composting and biofuel production. Furthermore, a lot of bioactive compounds could be produced from the agrowastes, which have many application possibilities such as functional food, pharmaceutical and cosmetic approaches. The nano-management of agro-wastes may include using nanotechnology to convert the agro-wastes into a valuable product. This topic still has several open questions, particularly under sustainable and green bioeconomy prespective.

“…Afterward, some other counties including USA, Italy, Philippines, Thailand, China, Korea and Japan followed vermiculture and vermicomposting practices in the world (Sinha et al, 2002). At present, application of vermicomposting technique for converting organic waste materials into valuable organic fertilizer are reported worldwide (Bellitürk, 2018;Joseph et al, 2020;Gutie´rrez-Miceli, et al, 2008).…”

“…Lantana camara, a perennial weed species which threatens native ecosystems could be converted into vermicompost by earthworm specie of Eisenia fetida and Eudrilus eugeniae in a mixture of cow dung (Devi and Khwairakpam 2020). Joseph et al (2020) suggested that cattle solid wastes generated from indigenous cow breeds were preferred by epigeic earthworm species Eudrilus eugeniae over exotic cow breeds. According to Balachandar et al (2019b), biomass of Ipomoea staphylina, an invasive weed species in India, mixed with cow dung and end products of the mushroom growing media could convert into vermicompost by Eudrilus eugeniae where 1:1:1 substrate mixture performed well in terms of N, P, K, Ca and sodium (Na) content.…”

With the rapid growth of global population, food production and waste management are considered to be two major challenges faced by people in 21 st century. Though application of chemical fertilizers enhances crop growth, vigor and yield thereby meeting the food security, it depletes the quality of environment and ecosystems. Recycling of organic wastes is considered to be a feasible solution which could mitigate the issues of waste management while uplifting the status of soil health and nutrients. The objective of this article is to reviews the currently available literature on vermicomposting as a tool for recycling of different organic waste materials and subsequent use as organic amendment to improve soil properties and as organic fertilizer to enhance growth and yield of various crops. Furthermore, models were proposed to improve education on vermicomposting as a solution for organic waste management among farmers, students, government offices and general public and develop as a community based microenterprise. Vermicomposting is defined as a process where earthworms convert organic wastes into humus like materials. It has been investigated worldwide taking its practical significance into account. Vermicompost is found to be a good source of plant macro nutrients, micro nutrients and growth regulators, including humic acid, indole acetic acid and kinetin. Microbes live in the alimentary canal of the earthworms improve the quality of vermicast hence vermicompost. Furthermore, vermicompost could absorb heavy metals in soil and water while eliminating of human pathogens such as Salmonella spp, fecal coliforms, Shigella spp, Enterobacter aerogenes, Enterobacter cloacae and eggs of helminthes. Reviewed literature indicated the potential of vermicomposting to be used as an efficient technique for bioconversion of organic wastes into a valuable organic fertilizer. Furthermore, the present review suggests vermicompost production as a micro-enterprise which could be used to uplift the livelihood of the resource poor farmers through economic empowerment while assuring sustainable crop production.
