Core Ideas Application of Char (coal combustion residue) at 67 Mg ha -1 (19.7 Mg char-C ha -1 ) increased soil C concentration Char application at 67 Mg ha -1 (19.7 Mg char-C ha -1 ) increased soil C stock in low C soils but not in a high C soil Low rates (<67 Mg ha -1 ) of Char application did not affect soil C concentration and stocks Char application increased sulfate, Ca, Mg, and Na concentrations but did not affect soil physical properties and crop yields Abstract Restoring soil carbon (C) lost due to intensive farming is a long-term endeavor under current conservation management practices. Application of coal combustion residue (293 g C kg -1 ) from a sugar beet (Beta vulgaris L.) processing factory, hereafter referred to as Char, could rapidly restore soil C and productivity in degraded croplands, but data on this potential strategy are unavailable. We assessed the impacts of Char application to two relatively low C soils (10.1 and 12.2 g C kg -1 ) and one relatively high C soil (17.3 g C kg -1 ) on soil C, soil physical and fertility properties, and crop yields in no-till systems in the Great Plains after 2 yr. Char was disked to 15 cm soil depth at Char-C
