From hydro-/biochar application to soils positive effects on soil characteristics and as a consequence on yield of crops were expected. The objective of this study was to compare the effects of maize biochar and maize hydrochar (HTC-char) amendments treated with or without digestate, as well as a wood biochar, mixed with or without digestate and mineral nitrogen fertilizer on yield, yield components, nutrient contents and quality of spring wheat. Therefore, a pot experiment was set up. Yield, yield components and quality were mainly influenced by nitrogen fertilizer. The application of HTC-char could have negative effects on yield and yield components of spring wheat. Hydrochar treated with digestate had no negative effects on yield of spring wheat.
