“…Then NH 3 emission began to decrease till the 7th day when there was little emission detected because of the exhaustion of the easily degradable organic nitrogenous substances. The results were similar to some previous reports on the massive emission of NH 3 in the initial stage of composting (Li et al, 2013;Nakhshiniev et al, 2014). In this study, NH 3 emission mainly took place on days 2-5 due to the degradation of numerous nitrogenous substances.…”

“…The nitrogen can be recycled for the plant growth, so it is very important to keep the nitrogen in the composting endproduct. However, about 40-80% of nitrogen was lost through NH 3 volatilization in the SS composting, which has been reported in the previous reports (Li and Li, 2015;Nakhshiniev et al, 2014). Moreover, "Kyoto Protocol" reported that N 2 O is a key greenhouse gas, that play a great role in the global warming, and its single-molecule warming potential is 296 times that of CO 2 (IPCC, 2013).…”

The present study included lab-scale sewage sludge (SS) composting amended by molasses and spent mushroom substrate (SMS) in 5 L composting reactor system. The influence of molasses and SMS amendment on nitrogen loss and humification of SS composting was evaluated. The results showed that SMS amendment, especially combination with molasses raised composting temperature, increased CO 2 volatilization, promoted organic matter degradation, improve germination index and humification process. The addition of SMS and molasses contain carbohydrates used as carbon source and energy substance by microorganisms could increase microbial activity and ammonia assimilation. In the SMS + molasses treatments, NH 3 volatilization was reduced by 33.1%–37.3% and N 2 O volatilization was only 17.8%–25.4% of that in the control treatment, furthermore, the nitrogen loss rate was reduced by 27.2%–32.2%. Consequently, the addition of SMS and molasses improved the compost maturity and reduced nitrogen loss in the SS composting process.

“…A commonly used method to reduce NH 3 losses is the immobilization of ammonium through addition of C‐rich materials, such as straw, corn borer, stalks, and bamboo increasing the ratio between C and N. However, the addition of C‐rich materials does not always reduce the loss of ammonia volatilization during composting because some high‐carbon materials are difficult to be used by microorganisms and it depends on the effectiveness of carbon in high‐carbon materials on microorganisms …”

Aliibacillus thermotolerans BM62 T is a novel thermophilic nitrifying bacterium, which belongings to the family Bacillaceae. A laboratory scale composting was done to evaluate the effect of adding strain BM62 T on nitrogen retention during the process of animal waste compost. During the whole composting process, the ammonia emission of the compost with BM62 T added was 29.71% lower than that of the control compost. In addition, the emission amount reduced in the warming and high temperature period accounted for 92.19% of the total emission amount reduced by the addition of strain BM62 T . In the early stage of composting (0-14 days), the ammonium content in the BM62 T -added compost was significantly lower than that of the control compost, while the content of nitrite and nitrate was significantly higher than that of the control compost. At the end of composting, the nitrate content in the BM62 Tadded compost (3.25 g/kg DM) was significantly higher than that of the control compost (0.14 g/kg DM). The number of thermophilic bacteria increased by 73.07% and that of thermophilic nitrifying bacteria increased by 75.56% in the compost with BM62 T added. While the number of thermophilic bacteria increased by 29.61% and that of thermophilic nitrifying bacteria increased by 31.72% in the control compost.These results showed that BM62 T could effectively reduce the ammonia emission especially during the high temperature period of compost, which make it has good application value in livestock and poultry manure compost treatment for promoting nitrogen retention.
