Salt-affected soils have poor structure and physicochemical properties, which affect soil nitrogen cycling process closely related to the environment, such as denitrification and ammonia volatilization. Biochar and polyacrylamide (PAM) have been widely used as soil amendments to improve soil physicochemical properties. However, how they affect deni...

Denitrification and NH3 volatilization are the main removal processes of nitrogen in coastal saline soils. In this incubation study, the effects of wheat straw biochar application at rates of 0, 2, 5, 10 and 15% by weight to saline soil with two salt gradients of 0 and 1‰ on denitrification and NH3 volatilization were investigated. The results show...

... The NO 3 − -N balance before and after the leaching experiment is shown in Fig. 7b, and the increment of NO 3 − -N was far lower than the decrement of NH 4 + -N. Therefore, it was speculated that during leaching, NH 4 + -N lost was transformed to volatile NH 3 (Liu et al., 2017;Mandal et al., 2019;Pan et al., 2021). Previous studies have reported that the addition of biochar could promoted the pH of soil (Hossain et al., 2020), which benefited to the transformation of NH 4 + -N to NH 3 (Mandal et al., 2019). ...
... Urea hydrolysis promotes NH 3 volatilization in flooded layer (Wang et al. 2012). The NH 3 volatilization was significantly correlated with the concentcing water (Pan et al. 2021) (Table 2, Fig. 6). The N loss of NH 3 volatilization is mainly concentrated in the tillering and jointing periods after applying fertilizer. ...
