Webnitrogen cycle. Nitrogen is one of the elements most likely to be limiting to plant growth. Like carbon, nitrogen has its own biogeochemical cycle, circulating through the atmosphere, lithosphere, and hydrosphere ( Figure 5 ). Unlike carbon, which is stored primarily in sedimentary rock, most nitrogen occurs in the atmosphere as an inorganic ... WebDenitrification. Denitrification is the microbial process of reducing nitrate and nitrite to gaseous forms of nitrogen, principally nitrous oxide (N2 O) and nitrogen (N 2 ). A large range of microorganims can denitrify. Denitrification is a response to changes in the oxygen (O 2) concentration of their immediate environment.
