Niche-based assessment of contributions of legumes to the nitrogen economy of Western Kenya smallholder farms (2007, background): “The amount of N contained in legume root biomass accounts for about 30% of the total plant N (Khan et al. 2002; McNiel et al. 1997).”
Nitrogen Rhizodeposition of Legumes (2011, background): “legume. Khan et al. (2002b) compared the use of leaffeeding and petiole-feeding methods in the field with four different species.”
Facilitative Root Interactions in Intercrops (2005, methodology): “…with 15N2 for N2 fixing plants, 15NH3, 13CO2 or 14CO2 in gas-tight enclosures, (ii) 15N stem labelling (Mayer et al., 2003) and shoot labelling of leaflets or petioles (Khan et al., 2002b), (iii) split-root labelling technique with, e.g., 15NO3 and 32PO4 (Ikram et al., 1994; Jensen, 1996d).”
Mixed-species plantations of Acacia mangium and Eucalyptus grandis in Brazil: 2: Nitrogen accumulation in the stands and biological N2 fixation (2008, background): “Such a feature was shown for other legume species in glasshouse experiments (Khan et al., 2002) and tropical forest plantations (Harmand et al.”

Farmers’ agronomic and social evaluation of productivity, yield and N2-fixation in different cowpea varieties and their subsequent residual N effects on a succeeding maize crop (2008, background): “Assuming 30% of the total plant N is contained in the roots (Rochester et al. 1998; Khan et al. 2002), then the roots potentially recycle between 21 and 37 kg N ha–1.”
Prospects and problems of simple linear models for estimating symbiotic N2 fixation by crop and pasture legumes (2010, background): “In recent years there has been considerable research effort directed at quantifying below-ground N of agricultural crops, especially legumes (e.g. Khan et al. 2002; Mayer et al. 2003; McNeill and Fillery 2008; McNeill et al. 1997; Wichern et al. 2008).”
