Abstract: The denitrification rates of freshwater and oligohaline tidal marsh soils with different textures (loam and sandy soils) in a subtropical estuary, and their responses to nitrogen (N) loading, were investigated. In both marshes, the denitrification rates varied significantly with the season only in loam soil. The denitrification rates were highest in oligohaline marsh loam soil and lowest in freshwater marsh sandy soil. NH4NO3 addition significantly increased the denitrification rates of all the marsh soils. Ou… Show more

“…It should be mentioned that some biogeochemical processes are often a function of soil properties (such as texture and water content), therefore, many end users of rating methods claim that natural attenuation processes are accounted for, even though not ex- It should be mentioned that some biogeochemical processes are often a function of soil properties (such as texture and water content), therefore, many end users of rating methods claim that natural attenuation processes are accounted for, even though not explicitly. Specifically, soil texture could influence the redox values suitable for DNT, which were found to be more favorable in clayey textured soils than in sandy textured soils [88,89]. Nevertheless, other important factors influencing DNT, like organic carbon substrates and Nr mass loading rates, are generally completely neglected.…”

“…Total N wet deposition rates in Sanjiang plain wetlands were about 7.57 kg ha −1 yr −1 in 2003–2004, and the inorganic N was the dominant component, contributing to 84.56% of total wet deposition (Sun et al, 2007). In general, the N deposition significantly increased the N loadings in aquatic ecosystems, which may alter microbial N cycling processes (Hu et al, 2021b). However, the responses of N cycling processes to N deposition may differ in various aquatic ecosystems, which should be further revealed to better understand the ecological impact of N deposition.…”

“…Moreover, hydrological connectivity is highly scale-affected, which is the reason why the interactions in larger scales require further experiments. Finally, how static and dynamic factors, such as soil texture (Hu et al, 2021) and tidal movements, influence hydrological connectivity is also crucially important to reveal the mechanism of hydrology-soil-plant interactions, where research gaps still remain.…”
