“…As a sustainable approach for addressing fecal waste, composting is currently encouraged prior to applying manure to land, and composting can reduce the volume and mass of manure as well as provide safer and more stable organic fertilizer or soil amendments [1,5,6]. Compost is used as a supply of nitrogen [7].…”

Currently, composting is one of the most effective methods for treating fecal waste on large-scale livestock and poultry farms, but the quality effects of different composting methods are different. In this study, we implemented four composting methods, including farmer compost (FC), anaerobic compost (AnC), mixed compost (MC), and aerobic compost (AC), to study the effects of different composting methods on nitrogen (N) losses while composting dairy manure. Our results showed that the germination indexes (GIs) of three of the composting treatments (AnC, MC, and AC) exceeded 80%, which met the maturity requirements for composted products. Ammonia (NH3) emissions were the main contributor to nitrogen losses, while accumulated nitrous oxide (N2O) emissions accounted for the lowest proportion of nitrogen losses. The cumulative N losses via the leachate of the AC treatment were the lowest and accounted for 0.38% of the initial total nitrogen (TN). The accumulated N losses of the AC, FC, AnC, and MC treatments accounted for 13.13% 15.98%, 15.08%, and 19.75%, respectively, of the initial TN. Overall, the AC method significantly reduced N losses via leachates, further reducing TN losses. This observation suggests that AC might be an appropriate method for highly efficient nitrogen management during dairy manure composting.

“…14a). Such an increase in root and shoot lengths was observed in studies recorded in green gram and black gram plants treated with wheat bran and rice husk compost, respectively, for growth promotion [29,30]. Similarly, different organomineral fertilizers and compost of neem and cassava peel enhanced the growth and yield of two varieties of cabbage (Brassica oleracea L.), namely Copenhagen market and F1 milor [31].…”

The application of agro-waste in the form of compost is an ecofriendly approach to minimize the use of chemicals for crop improvement. Hence, compost was prepared by the Indore method from banana spathe obtained from five popular varieties of banana cultivated in Tamil Nadu, India, and its growth promoting ability was tested on the rice cultivar CO-51. The banana spathe was applied as both an aqueous extract and compost to evaluate the growth parameters in bioassays and pot culture experiments. The compost improved the growth in terms of root length, shoot length, biomass, tillers, length, and width of flag leaf and yield in CO-51 rice cultivar significantly (p < 0.001%) when compared to the untreated control and fertilizer-treated plants. The maximum yield was observed in the treatment with Rasthali spathe. Biochemical analysis of the compost-treated rice plants showed an increase in chlorophyll, carotenoid, carbohydrate, protein, and amino acid content when compared to the untreated control plants. The results from the study suggest that the banana spathe compost could be used as an effective organic fertilizer for the growth of rice plants thus providing a strategy to reduce landfills, as well as the use of fertilizers, thereby further helping to protect the agroecosystem.

“…During decomposition process carbon will be mineralized as CO2 or assimilated by the soil microflora, microbial decayproducing both C humification and secondary C mineralization. The N content improved due to a concentration effect caused by degradation of labile OC compounds which reduced the weight of the decomposting biomass (Thiyageshwari et al 2017). The levels of decomposition of biomass can be influenced by several factors such as environmental physicochemical, biomass quality and content, and the composition of decomposers.…”

Abstract. Khoirunnisa NS, Anwar S, Santosa DA. 2020. Isolation and selection of cellulolytic bacteria from rice straw for consortium of microbial fuel cell. Biodiversitas 21: 1686-1696. Cellulose such as in rice straw can be utilized as an organic substrate in Microbial Fuel Cell (MFC) to generate electricity by microorganisms as a biocatalyst. This research aimed to get cellulose-degrading bacteria with high capability to degrade rice straw and able to be used as consortium with exoelectrogen bacteria in Microbial Fuel Cell. The stages of research included: (i) isolation of the bacteria using carboxymethylcellulose (CMC) agar medium, (ii) selection of the isolates for that purpose, (iii) enzyme assay and MFC performance test, and (iv) identification of selected isolate. There were 125 isolates that were obtained. Selection based on the ability to degrade cellulose as indicated by clear zone on CMC medium resulted in 23 isolates. Ten isolates belong to anaerobic facultative bacteria were selected. Three of them were synergistic with exoelectrogen bacteria. The three isolates were tested for exoglucanase (Avicel) and total enzyme activity (Filter Paper) with the highest results were 6.21 U/mL (isolate J404) and 5.88 U/mL (isolate J401), respectively. The optimum MFC performance was achieved by one isolate, J401, which produced highest voltage of 40.8 mV and a power density of 0.33 mW/m2. The best isolate, J401, was identified as Xanthomonas translucens based on 16S rRNA method.
