Fortification of micronutrients for efficient agronomic production: a review (2016, background): “Mo is required for N fixation by both symbiotic and free-living N-fixing bacteria, being a component of the nitrogenase enzyme system (Barron et al. 2009), and therefore, essential for legume cropping systems, and in efforts to enhance biological N-fixation to supplement mineral N-fertilization.”

The Nitrogen Paradox in Tropical Forest Ecosystems (2009, background): “Such facultative fixation is well recognized experimentally, in symbiotic fixers (Ingestad 1980, Olsen et al. 1975, Pate & Dart 1961) as well as in nonsymbiotic (heterotrophic) Nfixing bacteria in soils (Barron et al. 2009, Crews et al. 2000).”

Nitrogen and phosphorus interact to control tropical symbiotic N2 fixation: a test in Inga punctata (2013, background): “We did not examine the potential role of the trace element molybdenum in fixation (Barron et al. 2009; Wurzburger et al. 2012), as we focus on the two nutrients that have historically been considered the most critical to fixation.”
Biological nitrogen fixation by alternative nitrogenases in terrestrial ecosystems: a review (2020, background): “As described above, Mo limitation of BNF has been demonstrated across a wide range of ecosystems from low to high latitudes (Barron et al. 2009; Jean et al. 2013; Rousk et al. 2017; Silvester 1989; Wurzburger et al. 2012).”

Paradigm shift in plant growth control. (2015, background): “As small as this global net C fixation might be (if it occurs in forests at all), it must find an end, given forest density per unit land area is limited and C sequestration to soil organic matter would co-sequester nutrients away from growth and thus constrain NPP. Part of that ‘missing carbon’ may”
