Data on biological N<sub>2</sub> fixation by leguminous crops (pulses and soybeans) are obtained from the N in the harvested product (see nutrient withdrawal) following the approach of ([[Salvagiotti et al., 2008]]). Thus any change in the rate of biological N<sub>2</sub> fixation by legumes is the result of yield changes for pulses and soybeans. In addition to leguminous crops, IMAGE uses an annual rate of biological N<sub>2</sub> fixation of 5 kg N per ha for non-leguminous crops and grass, and 25 kg N per ha for wetland rice. N fixation rates in natural ecosystems were based on the low estimates for areal coverage by legumes ([[Cleveland et al., 1999]]) as described by Bouwman et al. ([[Bouwman et al., | Data on biological N<sub>2</sub> fixation by leguminous crops (pulses and soybeans) are obtained from the N in the harvested product (see nutrient withdrawal) following the approach of ([[Salvagiotti et al., 2008]]).
