      abstract     = {Optimal crop production depends on a supply of phosphorus.
                      Sugarcane bagasse ash (BA), a by-product of sugarcane
                      processing, contains up to 1.6 $wt\%$ phosphorus. BA use in
                      agriculture can reduce the dependency on rock phosphate.The
                      potential of BA as phosphorus fertilizer was tested for
                      soybeans on Oxisol soil under Brazilian field conditions.
                      Fertilizing effects of 40, 80 and 160 kg/ha P2O5 from BA
                      were compared to conventional fertilization with 40 kg P2O5
                      from triple-superphosphate (TSP). Additionally, BA/TSP
                      blends consisting of $70\%$ P2O5 from BA and 30 $\%$ from
                      TSP (resulting in 32, 65 and 130 P2O5 kg/ha) were evaluated
                      with respect to fertilizing efficiency. The bioavailability
                      of P2O5 from BA to soybeans was lower than from TSP, so that
                      doubling of P2O5 dose was necessary to compensate for the
                      lower offtake. Grain yields following BA-based
                      fertilizations did not statistically differ compared to TSP
                      fertilization, albeit tended to increase by $11\%$ when
                      fertilized with BA/TSP blend supplied at 65 kg P2O5/ha.
                      Thus, while 80 kg P2O5/ha in form of BA could replace 40 kg
                      P2O5/ha in form of TSP, fertilization with 65 kg P2O5/ha in
                      form of BA/TSP could save $50\%$ of TSP and increase the
                      grain yield.},
