Global inputs of biological nitrogen fixation in agricultural systems (2008, background): “Although natural 15N abundance has been widely utilised in agricultural settings, there are a number of potential limitations that restrict its application in natural ecosystems (Boddey et al. 2000).”
Woody legume fallow productivity, biological N2-fixation and residual benefits to two successive maize crops in Zimbabwe (2004, methodology): “That woody plant parts are less enriched in 15N than leaves has been widely reported (Shearer and Kohl, 1986; Boddey et al., 2000) and a plausible explanation is due to the internal cycling of plant N. Nitrogen from soil is first translocated to leaves and then retranslocated to twigs and branches,…”
Mixed-species plantations of Acacia mangium and Eucalyptus grandis in Brazil (2008, methodology): “…reference species, (iii) accounting for factors affecting d15N values within trees (sources of N, chemical form and depth of N taken up in the soil, mycorrhizal symbioses, etc.), and (iv) applying 15N labelled fertilizer on a sufficient area owing to cost limitations (Boddey et al., 2000).”
Greater root phosphatase activity in nitrogen‐fixing rhizobial but not actinorhizal plants with declining phosphorus availability (2017, methodology): “…on N fixation for overall N acquisition for each N-fixing species was estimated using the 15N natural abundance method (Shearer & Kohl 1986; Boddey et al. 2000; Unkovich et al. 2008), and the percentage of N content derived from the atmosphere (%Ndfa) was calculated with the following…”
Contribution of biological nitrogen fixation to Elephant grass (Pennisetum purpureum Schum.) (2011, methodology): “…availability of high-precision continuous-flow isotope-ratio mass spectrometers, the 15 N natural abundance technique has become the most widely used technique for evaluating biological nitrogen fixation (BNF) in the field (Shearer and Kohl 1986; Boddey et al. 2000; Unkovich et al. 2008).”
Nitrogen Transfer Within and Between Plants Through Common Mycorrhizal Networks (CMNs) (2003, methodology): “This technique and the N mass balance technique both yield similar data (Kohl and Shearer, 1980; Shearer and Kohl, 1986; Handley and Raven, 1992; Knowles and Blackburn, 1993; Handley and Scrimgeour, 1997; Högberg 1997; Boddey et al., 2000; Tjepkema et al., 2000; Robinson, 2001).”
Agricultural uses of plant biostimulants (2014, unknown): “2 0 0 1 ) , Herbaspirillum spp. (Pimentel et al. 1991), and Gluconoacebacter diazotrophicus (Boddey et al. 2001).”
Nitrogen-fixing bacteria associated with leguminous and non-leguminous plants (2009, methodology): “Instead, a common method is based on differences in the natural abundance of 15N contained in mineral sources of nitrogen compared to atmospheric nitrogen (Boddey et al. 2000; 2001).”
The Nitrogen Paradox in Tropical Forest Ecosystems (2009, background): “However, this assumption likely oversimplifies the considerable complexity observed in 15N across different soil N pools and fractionating paths of the plant-soil N cycle (Boddey et al. 2000; Evans 2001; Högberg 1997; Houlton et al. 2006, 2007).”
