000915930 520__ $$aSugarcane bagasse, the lignocellulosic remains of sugar cane processing is commonly burnt to generate electricity. 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 biofuels.
