Low pH and phosphorus are among major soil chemical constraints to Biological Nitrogen Fixation (BNF) and soybean production in sub-Saharan Africa. A screenhouse pot experiment was conducted at Sokoine University of Agriculture- Morogoro Tanzania, to examine the ameliorating effect of liming to pH, phosphorus uptake, BNF and yield of soybean grown on an ultisol. The experiment was a 33 factorial laid out as a split plot with two replications. Source of nitrogen (inoculation, non-inoculation and applied inorganic nitrogen) was main plot factor, while the subplots received combinations of lime and phosphorus. The levels of lime used for the incubation experiment were 0, 5 and 10 ton ha-1 while those of P were 0, 50 and 100 kg*ha-1. A commercial inoculant-Legumefix, was used for inoculation. Results indicated that liming significantly (P<0.05) raised the soil pH and that the interaction of lime and phosphorus showed significant (P<0.05) effect on nodulation and N2 fixation. Overall, application of 5 tons of lime per ha-1 and 100 kg P*ha-1 gave the best case scenario in terms of pH amelioration, P availability and BNF enhancement by the soybean-Bradyrhizobium symbiosis.
