•Gasification biochar increased plant-available water capacity and soil pH.•Straw gasification biochar improved plant and root development in coarse sandy soil.•Wood gasification biochar had either no or slightly negative effect on plant growth. Gasification biochar (GB) contains recalcitrant carbon...
