There remains conflicting evidence on the relationship between P supply and biological N2-fixation rates, particularly N2-fixing plant adaptive strategies under P limitation. This is important, as edaphic conditions inherent to many economically and ecologically important semi-arid leguminous tree species, such as Acacia senegal, are P deficient. Our research objective was to verify N acquisition strategies under phosphorus limitations using isotopic techniques. Acacia senegal var. senegal was cultivated in sand culture with three levels of exponentially supplied phosphorus [low (200_mol of P seedling?1 over 12 weeks), mid (400_mol) and high (600_mol)] to achieve steady-state nutrition over the growth period. Uniform additions of N were als...
