The biological nitrogen-fixation process provides about 60% of the total production of fixed nitrogen from all natural and industrial sources (1). Since 1930 (2), molybdenum was believed to have an absolutely essential role in nitrogen fixation, even though early on vanadium was demonstrat

The symbiosis between rhizobia and legumes produce about the same amount of ammonia worldwide as the chemical industry of nitrogen fertilizers and this fixation occurs in nodules.
