The Nitrogen Paradox in Tropical Forest Ecosystems (2009, background): “…studies have shown that heterotrophic fixation can be down-regulated by additions of N fertilizer (Barron et al. 2009, Crews et al. 2000; but see Reed et al. 2007) and that rates may also be controlled by molybdenum in some tropical soils (Barron et al. 2009) and P in others (Reed et al. 2007).”
Relationships among phosphorus, molybdenum and free-living nitrogen fixation in tropical rain forests: results from observational and experimental analyses (2013, background): “Accordingly, the relatively high P demand of N-fixers creates the potential for P limitation to N fixation, and multiple studies have shown that P additions stimulate the process (Eisele et al. 1989; Smith 1992; Benner et al. 2007; Reed et al. 2007a, b).”
Stoichiometric imbalances between terrestrial decomposer communities and their resources: mechanisms and implications of microbial adaptations to their resources (2014, background): “…microbes is distributed heterogeneously, with hotspots of N fixation in habitats with high C and low N availability, i.e., in woody debris, leaf litter and the forest floor, and lowest rates in mineral soils (Hope and Li, 1997; Wei and Kimmins, 1998; Reed et al., 2007; Cusack et al., 2009).”
Bacteria and fungi can contribute to nutrients bioavailability and aggregate formation in degraded soils. (2016, unknown): “Moreover, P limitation in soil decreases the activity of nitrogenase enzyme in N-fixing bacteria, because both autotrophic and heterotrophic bacteria require high ATP for cellular N2 fixation (Reed et al., 2007,2011; Pérez et al., 2014).”
Global change effects on humid tropical forests: Evidence for biogeochemical and biodiversity shifts at an ecosystem scale (2016, background): “…when soil N levels are relatively high, as well as on leaf litter, in arboreal mosses and lichens, and on leaf epiphylls, contributing substantially to overall fluxes of N into tropical forests [Carpenter, 1992; Cusack et al., 2009a; Forman, 1975; Goosem and Lamb, 1986; Reed et al., 2007, 2008].”
