Highlights Increasing HTC temperature (190, 210 and 230 °C) resulted in physico-chemical and structural differences in the HCs. HC addition to a Podzol potentially resulted in a positive priming effect in the free OM fraction after 1 year. The more stable SOM fractions of the HC-amended Podzol contained more OC than the (HC free) control after 1 year.
