Microbiological regulation of the biogeochemical nitrogen cycle, for us to devise management practices in agricultural ecosystems, which will optimize plant root uptake of nitrogen and minimize nitrogen losses from the systems. Some aspects of the individual microbiological processes in the nitrogen cycle are discussed and their importance for an efficient manag

The role of the atmosphere in nitrogen cycling,de. Atmospheric emissions of N.O and NH. are almost entirely due to biological activity on the continents and in the oceans. The combustion of fossil fuels and biomass is the principal source of NO.. The only relevant chemical transformations in the troposphere are the oxidation of NO. to NO.. and t

Nitrogen in shifting cultivation systems of Latin America,ls that predominate in 82% of the region, namely Oxisols and Ultisols, have a fairly high total N content. Contrary to conventional wisdom, the bulk of the N in tropical rainforests is present in the soil, and not in the biomass. Losses of N through clearing and burning are about 20–25% of the N exi
