Grasslands (natural, semi-natural and improved) occupy approximately one-third of the terrestrial biosphere are key for global ecosystem service provision, storing up to 30% soil organic carbon (SOC). To date, most research on (C) sequestration has focused croplands where levels native matter (SOM) typically low significant potential exists replenish SOM stocks. However, with renewed push achieve "net zero" C emissions by 2050, grasslands may offer an additional store, utilising tools such as biochar. Here, we critically evaluate biochar a technology increasing grassland stocks, identifying number practical, economic, social legislative challenges that need be addressed before widescale adoption achieved. We assess current knowledge within field in context provision provide opinions applicability amendment different types (improved, semi-improved unimproved) effect using range application techniques topsoil subsoil. concluded question remains, is it possible managed store more C, without causing loss services? address this future must take multidisciplinary holistic approach when evaluating role at sequestering mitigate climate change.The online version contains supplementary material available 10.1007/s42773-023-00232-y.
