“…NH 3 volatilization was estimated as 1.4% of fertilized N [30]. Recently, some reports have pointed out the possibilities that anaerobic oxidation of ammonium (anammox) can be a significant process of nitrogen dynamics in a flooded paddy soil [31][32][33]. However, N 2 emission via anammox from rice paddy was not considered in this study due to their limitation in quantitative evaluation.…”

“…The N loss in this study was higher than reported previously (e.g., +1.28 g N m −2 in [11], +0.4 g N m −2 in [10]). As described above, uptake of soil nitrogen by rice in paddy fields converted from upland fields could be larger than those in unconverted paddies [31,32]. To avoid over-luxuriant growth and lodging due to the increased nitrogen uptake, nitrogen fertilization to paddy fields converted from upland fields is limited.…”

Abstract:In northern Japan, declines in soil nitrogen fertility have occurred in paddy-upland rotation systems with soybean cultivation. A six-year lysimeter experiment was conducted to evaluate the nitrogen budget in paddy-upland rotation (three-year for upland soybean, then three-year for flooded paddy rice) and to clarify the effect of preceding compost application (immature or mature compost over four consecutive years of forage rice cultivation) on the nitrogen budget and soil nitrogen fertility. Available soil nitrogen throughout the experimental period and soybean and rice yields in both compost application plots tended to be higher than those in the control plot. The nitrogen budgets during both soybean and rice cultivation were negative, and the amount of nitrogen loss in both compost application plots tended to be higher than that in the control plot. The nitrogen loss during rice cultivation (−2.3 to −4.3 g N m −2 year −1 ) was less than that during soybean cultivation (−9.6 to −14.6 g N m −2 year −1 ). Nitrogen loss estimated based on the nitrogen budget agreed well with that estimated based on changes in soil nitrogen storage during soybean cultivation but not during rice cultivation, suggesting underestimation of nitrogen loss from the rice paddy.

“…Heterotrophic denitrification was considered to be the only known pathway for the loss of fixed nitrogen to the atmosphere for decades until the discovery of anammox bacteria in a wastewater treatment plant (Mulder et al 1995). Subsequently, anammox bacteria were detected with broad biogeographic distribution in various natural ecosystems, including marine sediments (Thamdrup and Dalsgaard 2002;Trimmer and Nicholls 2009;Brabandere et al 2014;Shao et al 2014;Dang et al 2016), estuarine sediments (Dale et al 2009;Dang et al 2010;Li et al 2011;Wang et al 2012a, b;Dang et al 2013), and paddy soils (Zhu et al 2011;Nie et al 2015;Yang et al 2015). The relative contribution of anammox to dinitrogen production can vary widely, with >80% of total N 2 production observed in the eastern tropical South Pacific oxygen minimum zone (OMZ) off the coast of northern Chile (Brabandere et al 2014).…”

Purpose Despite its importance, anammox (anaerobic ammonium oxidation) in estuarine sediment systems remains poorly understood, particularly at the continental scale. This study aimed to understand the abundance, diversity, and activity of anammox bacteria and to determine the main factors influencing the anammox process in estuarine sediments in China. Materials and methods Estuarine sediments were collected from 18 estuaries spanning over 4000 km. Experiments using an 15 N-tracer, quantitative PCR, and clone library construction were used to determine the activity, abundance, and diversity of anammox bacteria. The impact of environmental factors on anammox processes was also determined.Results and discussion The abundance of the anammoxspecific hydrazine synthase (hzsB) gene ranged from 1.8 × 10 5 ± 3.4 × 10 4 to 3.6 × 10 8 ± 7.5 × 10 7 copies g −1 dw. Candidatus Scalindua, Brocadia, Kuenenia, Jettenia, and two novel unidentified clusters were detected, with Scalindua dominating the anammox population. Additionally, the abundances of Scalindua, Kuenenia, and Brocadia were found to be significantly correlated with latitude. The anammox rates ranged from 0.29 ± 0.15 to 13.68 ± 3.98 nmol N g −1 dw h −1 and contributed to 2.39-82.61% of total N 2 production. Pearson correlation analysis revealed that the anammox rate was positively correlated with total nitrogen, total carbon, and temperature, and was negatively correlated with dissolved oxygen (DO). The key factors influencing the hzsB gene abundance were ammonium concentration, salinity, and DO. Ammonium concentration, pH, temperature, and latitude were main variables shaping the anammox-associated bacterial community. Conclusions Our results suggested that anammox bacteria are ubiquitous in coastal estuaries in China and underline the importance of anammox resulting in N loss at a continental scale.

Anaerobic ammonium oxidation with nitrite reduction to dinitrogen (termed anammox) has been reported to be an important process for removing fixed nitrogen (N) in marine ecosystems and in some agricultural and wetland soils. However, its importance in upland forest soils has never been quantified. In this study, we evaluated the occurrence of anammox activity in two temperate forest soils collected from northeastern China. With 15 N-labeled NO 3 ؊ incubation, we found that the combined potential of the N 2 production rates of anammox and codenitrification ranged from 0.01 ؎ 0.01 to 1.2 ؎ 0.18 nmol N per gram of soil per hour, contributing 0.5% to 14.4% of the total N 2 production along the soil profile. Denitrification was the main pathway of N 2 production and accounted for 85.6% to 99.5% of the total N 2 production. Further labeling experiments with 15 NH 4 ؉ and 15 NO 2 ؊ indicated that codenitrification was present in the mixed forest soil. Codenitrification and anammox accounted for 2% to 12% and 1% to 7% of the total N 2 production, respectively. Two anammox species, "Candidatus Brocadia fulgida" and "Candidatus Jettenia asiatica," were detected in this study but in very low abundance (as indicated by the hzsB gene). Our results demonstrated that the anammox process occurs in forest soils, but the contribution to N 2 loss might be low in these ecosystems. More research is necessary to determine the activities of different N 2 releasing pathways in different forest soils. IMPORTANCEIn this study, we examined the anammox activity in temperate upland forest soils using the 15 N isotope technique. We found that the anammox process contributed little to the N 2 production rate in the studied forest soil. Two anammox organisms, "Candidatus Brocadia fulgida" and "Candidatus Jettenia asiatica," were detected. In addition, we found that codenitrification was another N 2 production pathway in forest soils. Our results could contribute to the understanding of soil gaseous N losses and microbial controls in forest soils.
