                      Recycling strategies for the resulting ashes rarely take the
                      remaining plant nutrients into account. The objective of
                      this study was to investigate the potential of ashes sourced
                      from combustion and gasification of bagasse alone and in
                      combination with chicken manure and sewage sludge,
                      respectively, as fertiliser for soybeans. The analyses were
                      based on chemical ash characterisation, 31P NMR, X-ray
                      diffraction, sequential phosphorus (P) extraction, P
                      extraction in citric acid and greenhouse pot experiments
                      with soybean plants. Fertilization effects were lower than
                      those of triple-superphosphate and K2SO4 and depended on
                      plant P availability. Calcium-based phosphates dominated in
                      all ashes and determined plant P availability. XRD analyses
                      revealed whitlockite (Ca9M(PO4)7) and CaK2P2O7 in all ashes,
                      while AlPO4 was detected only in an ash with low plant P
                      availability and two undefined P phases and Ca(Na,K)PO4 in
                      ashes with high plant P availability. In conclusion, plant P
                      availability was highest in alkali-rich ashes, as observed
                      in ashes from co-processing bagasse with chicken manure. To
                      increase plant P availability in ashes, we recommend
                      co-combustion of the biomass with sodium and potassium rich
