To meet the current need for sustainable development, vermicomposting (VC), a natural, eco-friendly, and cost-effective technology, can be wise selection bioconversion of organic wastes into value-added by-products. However, no one has tried to establish VC technology as an economically by exploring its linkage circular bioeconomy. Even, researcher made any effort explore usability earthworms (EWs) protein supplement while assessing economic perspectives technology. Very few studies are available on greenhouse gas (GHG) emission potential Still, contribution towards non-carbon waste management policy is not yet explored. In review, genuine been inspect bioeconomy, along with evaluating capability bioremediate generated from domestic, industrial, agricultural premises. The EWs source also explored strengthen Moreover, comprehensively demonstrated highlighting carbon sequestration GHG potentials during treatment wastes. It observed that cost food production was reduced 60-70% replacing chemical fertilizers vermicompost. implication vermicompost significantly lessened harvesting period crops, thereby helping farmers attain higher profits cultivating more crops in single calendar year same plot. Furthermore, could hold soil moisture long time, lessening water demand up 30-40%, which, turn, frequency irrigation. Also, replacement resulted 23% increment grapes' yield, engendering extra profit 110000 rupees/ha. Nepal, produced at 15.68 rupees/kg, whereas it sold local market rate 25 rupees/kg manure, ensuring net 9.32 embraced 63% crude protein, 5-21% carbohydrates, 6-11% fat, 1476 kJ/100 g metabolizable energy, wide range minerals vitamins. contained 4.11, 2.04, 4.43, 2.83, 1.47, 6.26 g/kg (on basis) leucine, isoleucine, tryptophan, arginine, histidine, phenylalanine, respectively, enhancing acceptability EW meal (EWM) supplement. inclusion 3 5% EWM diet broiler pullets 12.6 22.5% increase their feed conversion ratio (FCR), respectively after month. Similarly, when 100% fish substituted 50% meal, FCR growth Parachanna obscura were increased substantially. maize crop residues mixed pig cow dung, biochar, presence Eisenia fetida EWs, yielded only 0.003-0.081, 0-0.17, 130.40-189.10 CO2-eq.kg-1 emissions CO2, CH4, N2O, respectively. tomato stems dung ensured 2.28 5.76 CO2 CH4 Additionally, application 5 t/ha improved proportion aggravated sequestration. land micro-aggregation cut down tillage, reducing triggering significant findings review suggest potentially contributes concept substantially negotiates emissions, complies policy, reinforcing sound environmentally benevolent bioremediation alternative.

Drivers and barriers in farmers’ adoption of vermicomposting as keys for sustainable agricultural waste management

International Journal of Agricultural Sustainability, Journal Year: 2023, Volume and Issue: 21(1)

Published: July 5, 2023

The conversion of agricultural waste into organic fertilizer through vermicomposting is a sustainable management solution and an income source for producers. Most the in Iran burned, triggering array negative consequences. Vermicompost production at farm level rarely practiced Iran, farmers play central role. study aimed to identify factors influencing adoption on-farm its (number cycles), barriers it, provide adapted policy recommendations. used mixed-method approach, with survey on 142 semi-structured interviews stakeholders. showed that attitude (β = 0.515, sig. 0.01), subjective norms 1.745, training 2.160, safe spraying 2.915, integrated pest 1.793, 0.01) influenced participation vermicomposting. Some revealed by qualitative research were initial investment cost, farmers’ short-term vision, lack necessary infrastructure, subsidies. complements scant information behavior proves understanding essential remove engage Practical recommendations based findings support management.
