The 4th International Nitrogen Conference: N-2007, Agriculture, Development, and Nitrogen: A problem of too little or too much The last 40 years have seen an extraordinary change in the global nitrogen cycle. As recently as the 1960s, nitrogen availability on Earth was controlled by natural processes, but the human creation of synthetic nitrogen fertilizer and the release of nitrogen from fossil-fuel combustion now match the natural rate of formation of reactive nitrogen on the planet's landscape.
