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

Professor Louis Schipper talks about soil carbon

Louis Schipper talks to Bryan Crump on RNZ Nights about soil carbon. He talks about soil organic matter, soil density, nutrients (nitrogen, phosphorus, sulphur), land use and the ways we can store more carbon in soil to reduce the amount of carbon dioxide in the atmostphere without reducing food production.

Louis also talks about the 4 pour mille initiative and its challenge to increase carbon content of soils by 0.4% per year to offset fossil fuel emissions.
