MOLYBDENUM LIMITS NITROGEN FIXATION.

The article reports that biogeochemists discovered that the limiting nutrient called molybdenum dictates the bacterial nitrogen fixation rate in tropical soils. It states that the discovery of molybdenum is important for the development of global biogeochemical cycles study because it restricts plant growth and carbon dioxide uptake by plants. It also notes that nitrogen fixation biologically converts nitrogen from air into ammonium that is used by plants as a fertilizer.
