Matsusada et al. (2002) have shown that NH3 emissions from composting animal manure varied from 323 mg/kg to 2840 mg/kg for swine manure, from 41 mg/kg to 458 mg/kg for dairy manure, and from 15 mg/kg to 2740 mg/kg for poultry manure for aeration rates ranging from 0.2 to 1.4 L/(min kg) and C/N ratios from 13 to 43 for swine, 19 to 42 for dairy, and 19 to 56 for poultry, respectively.

Mar 1, 2020 · Nevertheless, livestock manure composting process could not totally eliminate the pathogenic risk due to the control of core temperature (<70 °C) during composting, and the compost could still be a source for pathogens disseminating into soil ecosystem via fertilization (Dharmasena and Jiang, 2018, Noble, 2011, Sharma and Reynnells, 2016).
