Nutrient Dynamics (2004, background): “Biological N fixation by free living (Kennedy and Islam, 2001), associative (Boddey, 1987; Steenhoudt and Vanderleyden, 2000), and symbiotic organisms (Tajima et al., 2000; Unkovich and Pate, 2000; Wall, 2000) was extensively studied because of the large impact of this process on plant productivity.”

Net nitrogen balances for cool-season grain legume crops and contributions to wheat nitrogen uptake: a review (2001, background): “While there is no doubt that this can occur, it is by no means universal since legumes may often take up as much or more soil mineral N than comparable non-legume crops (Unkovich and Pate 2000).”
Evaluation of Co-inoculation of Bradyrhizobium japonicum and Phosphate Solubilizing Pseudomonas spp . Effect on Soybean (Glycine max L. (Merr.)) in Assossa Area (2012, background): “According to Unkovich and Pate (2000), the amounts of N2-fixed (kg ha -1 ) by soybean have been up to 450 Kg N ha -1 .”
Nitrogen fixation with the soybean crop in Brazil: Compatibility between seed treatment with fungicides and bradyrhizobial inoculants (2009, background): “Symbiotic associations with diazotrophic rhizobial strains occur with many legume species, but soybeans are amongst the most efficient at fixing N2 (Unkovich and Pate, 2000; van Kessel and Hartley, 2000; Giller, 2001) and, in Brazil, it has been estimated that rates of N2 fixation in soybean can exc”
The Importance of Nitrogen Fixation to Soybean Cropping in South America (2005, positive): “derived from fixation estimated at 53%, the contribution of BNF to N accumulation was 178 kg N ha -1 ( Unkovich and Pate, 2000 ).”
Global inputs of biological nitrogen fixation in agricultural systems (2008, background): “…were summarised (Peoples and Craswell 1992; Herridge and Danso 1995; Peoples et al. 1995; Wani et al. 1995; Jensen 1997; Unkovich et al. 1997; Schulz et al. 1999; Unkovich and Pate 2000; Giller 2001; Rochester et al. 2001; Turpin et al. 2002; Aslam et al. 2003; Shah et al. 2003).”

Nitrogen Rhizodeposition of Legumes (2011, background): “the entire root biomass is challenging, as many roots are fine and fragile and difficult to recover by wet sieving (Bergersen et al., 1989; Chapman and Myers, 1987; Toomsan et al., 1995; Russell and Fillery, 1996b; Dalal et al., 1997; Rochester et al., 1998; Unkovich and Pate, 2000).”
