Plants & GHGs

The NZAGRC’s former nitrous oxide and soil carbon work streams were combined into one programme this year. This ensures a strong overall framework, closer communication and full GHG analyses across the programme. The programme focusses on three key areas:

1. Identifying and prioritising plant traits for low GHG emissions;

2. Mitigation practices to maintain soil carbon and reduce nitrous oxide emissions at paddock scale; and

3. Defining the achievable soil carbon stabilisation capacity of New Zealand grassland soils.

Current progress and research stories

Positive results for novel nitrous oxide inhibitors

An initial study to determine the impact of a novel inhibitor was conducted in 2017/18. After 36 days urine from treated animals had 50% lower nitrous oxide emissions than untreated animals. This work will be expanded in 2018/19.
