The Global Nitrogen Cycle
The geobiology of nitrogen is dominated by large inert reservoirs and small biological fluxes. The largest reservoirs are nitrogen gas (in the atmosphere and dissolved in the ocean) and sedimentary nitrogen (sequestered in continental crust). Because most organisms cannot utilize gaseous nitrogen, we distinguish between fixed nitrogen compounds (which contain no N–N bonds) that are biologically...
متن کاملNitrogen: regional contributions to the global cycle
N itrogen is critical for life on Earth: it is an integral component of all amino acids, the basic constituents of protein. Although elemental nitrogen is abundant-the Earth's atmosphere is 79 percent nitrogen-the availability of nitrogen often limits the productivity of plant communities, whether natural vegetation or agricultural crops. This is because only certain forms of nitrogen are avail...
متن کاملNitrogen budgets and losses in livestock systems
Livestock farming systems encompass (i) grazing, (ii) mixed, and (iii) land-less systems. These systems convert crop protein into animal protein with an efficiency ranging from 5% to 45%, depending on animal type, system and management. The nitrogen (N) in the remaining fraction (55– 95%) is in urine and dung, and is conducive to N losses. This paper reviews N input–output budgets and N losses ...

متن کاملHuman Alteration of the Global Nitrogen Cycle: Sources and Consequences
Nitrogen is a key element controlling the species composition, diversity, dynamics, and functioning of many terrestrial, freshwater, and marine ecosystems. Many of the original plant species living in these ecosystems are adapted to, and function optimally in, soils and solutions with low levels of available nitrogen. The growth and dynamics of herbivore populations, and ultimately those of the...
