The carbon balance of temperate grasslands part I: The impact of increased species diversity

S. Rutledge, A.M. Wall, P.L. Mudge, B. Troughton, D.I. Campbell, J. Pronger, C. Joshi, L.A. Schipper, The carbon balance of temperate grasslands part I: The impact of increased species diversity, Agriculture, Ecosystems & Environment, Volume 239, 2017, Pages 310-323, ISSN 0167-8809, http://dx.doi.org/10.1016/j.agee.2017.01.039.

Highlights

  • 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.
