Bioconversion of agro, cattle waste and blended soil into manure by vermicomposting technology

In the present study, cow dung, saw dust, and blended soil were taken for (manure) biofertilizer production through vermicomposting (Eisenia fetida) experimental method. This work reports with the results of E. fetida in the mixture of blended soil, cow dung, and saw dust in different ratios for 60-day compost experimental trial. In all the experimental sets, the pH levels were not changed. The nitrogen content was changed in highest levels as 0.025% in B1, B2, B3, B4, and A4 experiments. The maximum phosphorous content was noted as 33.77% in B3 and 29.11% in A4, and the maximum potassium level was noted 33.77% in B3. The total organic carbon (TOC) levels were renowned at premier level, and slight changes of electrical conductivity were noted in all experimental sets. Nitrogen, phosphorous, and potassium contents were recorded high level as 1:3:3 and 1:4:4 ratios of composed agro and cattle waste mixture on the 45th and 60th days. The present study was clearly showed and suggested that the vermicomposting technology is an exchange, renewable, and cheap cost technology for the production of good quality eco-friendly fertilizers for plants if mixed with blended soil, cow dung, and saw dust in the ratio of 1:4:4.
