Carbon budget of an intensively grazed temperate grassland with large quantities of imported supplemental feed

Management of agricultural grasslands can alter soil carbon (C) stocks, and quantifying the effects of different management regimes is important to inform global greenhouse gas (GHG) mitigation strategies. Here, we report the net ecosystem carbon balance (NECB) over three years for an intensively managed rotationally grazed New Zealand dairy farm importing 11.6 t DM ha−1 y−1 (526 g C m−2 y−1) as supplemental feed. We investigated whether...
