(redirected fromNitrogen cycling) Thesaurus Medical Encyclopedia nitrogen cycle n. The circulation of nitrogen in nature, consisting of a cycle of chemical reactions in which nitrogen from the atmosphere is fixed in compounds in soil or water, assimilated by plants and animals, released to the soil...
Nitrogen cycling process and dynamic change over 2 years were studied in 21-year-old planted dahurian larch (Lurix gmelinii (Rupr) Rupr.) in the eastern part of northern China. N concentrations in the plants varied by tissue, age, position in tree and season. In the aboveground components ...
17), but many other factors in situ can regulate the process. Thus, in the literature surveyed there is no clear temperature regulation of denitrification, anammox, or DNRA. This evidence suggests that temperature is not a limiting factor for nitrogen cycling, and the disproportionately large ...
Denitrification is the most studied nitrogen cycling process in groundwater to-date, due to its importance for nitrogen pollution removal [5], although operation of the truncated pathway produces less desirable forms of inorganic nitrogen - NO2-due to its toxicity [24], and greenhouse gases NO ...

By the beginning of the second half of the 19th century, it was known that N was a common element in plant and animal tissues, that it was indispensable for plant growth, that there was constant cycling between organic and inorganic compounds, and that it was an effective fertilizer. ...
Aims We studied the effects of green manuring on the nitrogen (N) cycling process in different paddy soils. Methods Field experiments conducted in Hunan, Jiangxi, Henan and Fujian provinces in south China to investigate the responses of rice yield, soil properties, and functional genes involved ...

experimental and field research designs must consider both. We suggest future research to characterize additives, especially in controlled studies of organismal responses, so that their influence can be better assessed. If certain additives are found to inhibit coastal N cycling, their use in plastics...
