Table 3: Effect of low initial C/N ratio on aerobic composting of swine manure with rice straw
In this study, a lower initial C/N ratio (20) could reduce 172 kg rice straw per ton fresh swine manure than a higher initial C/N ratio (25), and more swine manure could also be treated.
Therefore, the addition of rice straw could be considered to reduce to C/N ratio of 20, and a low initial C/N ratio (20) should be considered in the composting of swine manure with rice straw.
