The carbon balance of temperate grasslands part II: The impact of pasture renewal via direct drilling

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 II: The impact of pasture renewal via direct drilling, Agriculture, Ecosystems & Environment, Volume 239, 2017, Pages 132-142, ISSN 0167-8809, http://dx.doi.org/10.1016/j.agee.2017.01.013

Highlights

  • Two blocks had pastures renewed (PR) by direct drill. A third block was a control.
  • The PR blocks had smaller positive NEPs than the control block during the PR year.
  • Duration of fallow is important in determining total CO2 losses due to PR
  • Pasture renewal led to a negative carbon balance (soil C loss) for the PR year
  • Addition of C (e.g. manure, effluent, feed) helps to mitigate soil C loss due to PR.
