- Annual C balances were measured for four years over three pastoral blocks on a New Zealand dairy farm.
- Two blocks were renewed to low and high diversity swards, and one block left as an unmodified control.
- Pasture renewal to either sward increased dry matter production relative to unmodified control.
- Renewal to high diversity sward resulted in reduced C loss compared to renewal to low diversity.
- Renewal to neither high nor low diversity sward had benefits for C sequestration over the unmodified control.
