Abstract: 
Recycling of phosphorus (P) from slaughterhouse waste, production of bone char (BC) and its use as fertilizer is a promising approach to close nutrient cycles but the fertilizer value of BC is not sufficiently clear. Therefore, two BCs (BC and sulfur-enriched BC (BCplus)) were tested in comparison with highly water-soluble triple superphosphate (TSP) in a perennial pot experiment with maize as test plant with high P-requirement. The fertilizers affected both the dry matter yields, and the P concentration of maize in the general order BCplus, TSP > BC. The P uptake of maize in the TSP treatment accounted for 38% of the applied P in the first experimental year and decreased subsequently. By contrast, the P uptake in the BCplus treatment remained quite stable over time. In conclusion, the sulfur-enriched BCplus is able to maintain sufficient P availability to crops in the medium term and can be recommended as fertilizer.
