“…Due to limited data, our results showed only in P. amphibium stand the effect of standing water depth on the spatial variation of N 2 O emissions. These results were consistent with some other studies demonstrating the key role of water table depth (especially ground water depth) in soil N cycling processes in the interface of aquatic and terrestrial ecosystems (Hefting et al 2003(Hefting et al , 2004.…”

“…The annual plant N uptake was the highest and the annual net N mineralization rate accounted for 37% of that uptake. The lower net N mineralization (72.24 kg N·ha [19,74,75]. Third, the N-rich and wet MM and HM BAF stands exhibited restricted net N transformation rates and N availability unlike high inorganic N concentration in bulk soils and low C:N ratio in leaf litters and soils.…”

“…Environmental controls of N mineralization and availability, particularly temperature and soil moisture, have been investigated through a theoretical model [11], literature review [9,12], laboratory experiments [13][14][15], and field manipulations [16][17][18][19]. For example, soil moisture varies significantly in space and time, and affects various biogeochemical processes in different ways [20][21][22].…”

Soil nitrogen (N) processes and inorganic N availability are closely coupled with ecosystem productivity and various ecological processes. Spatio-temporal variations and environmental effects on net N transformation rates and inorganic N concentrations in bulk soil and ion exchange resin were examined in an upland pine forest (UPF) and a bottomland alder forest (BAF), which were expected to have distinguishing N properties. The annual net N mineralization rate and nitrification rate (kg N·ha) were within the ranges of 66. in the BAF, respectively. In the BAF, which were assumed as N-rich conditions, the net N mineralization rate was suppressed under NH4 + accumulated soils and was independent OPEN ACCESS Forests 2015, 6 2942 from soil temperature. On the other hand, in the UPF, which represent moderately fertile N conditions, net N transformation rates and N availability were dependent to the generally known regulation by soil temperature and soil water content. Stand density might indirectly affect the N transformations, N availability, and ecosystem productivity through different soil moisture conditions. The differing patterns of different inorganic N indices provide useful insight into the N availability in each forest and potential applicability of ion exchange resin assay.

“…In addition, the elevated water table and flooding due to intense precipitation can easily create anaerobic conditions and increase the supply of OM, which is used by denitrifiers as electron donors. A previous study performed in various ecosystems including wetland ecosystems, forest and riverine riparian zones reported increased denitrification rates as the water table rose (Hill 1996;Freeman et al 1997;Hefting et al 2004;Peter et al 2012). However, the decrease in water table due to extreme drought could increase nitrous oxide emissions produced by denitrification in nutrient poor sites (such as stream sediments).…”

Sediment denitrification is an important nitrate (NO 3 -) removal process from agricultural streams. The direct and indirect factors that control denitrification rates in tributary sediments can vary depending on the types of agricultural activities and vegetation. Our research investigated (1) tributary sediment denitrification rates in a grassland stream affected by pasture ecosystems and a forest stream affected by N fertilization; and (2) the environmental factors that determine denitrification rates in tributary sediments. The denitrification enzyme activity (DEA) in grassland stream sediments is positively correlated with precipitation likely due to the increased nutrient exchange rates between stream water and sediments, and was higher than in forest stream sediments, leading to a decrease in NO 3 -concentration ([NO 3 -]) in stream sediments. The DEA in riparian sediments was regulated by carbon concentrations and did not contribute to NO 3 -removal from the riparian sediment in grassland and forest streams. Thus, environmental factors affected by different types of agricultural activities and vegetation might regulate denitrification rates and in agricultural stream ecosystems.
