Overview

Enhancing soil carbon stocks has the potential to assist New Zealand in meeting its international greenhouse gas emissions obligations. Full inversion tillage has been identified as a promising practical management manipulation that can increase soil carbon storage and field testing of the approach has already commenced with funding from the MPI GPLER fund. The full inversion tillage approach could have consequences for emissions of nitrous oxide from urine deposited by grazing livestock and from nitrogen fertiliser applications.

The Ministry for Primary Industries is seeking proposals from New Zealand based research providers to undertake comprehensive long term nitrous oxide measurements from the existing full inversion tillage trials being funded under the GPLER contract. The method used for measuring nitrous oxide emissions needs to be consistent with the methodology currently being used in the GPLER programme. Chamber methods are being used in the short-term nitrous oxide measurements and the same methodology needs to be followed for the longer term measurements to ensure data continuity.

Funding of NZD $240,000 is available for this project. Based on this funding, a focused research programme is sought.

The expected outcomes of the research programme are:
• An assessment of whether full inversion tillage undertaken to enhance carbon accumulation influences nitrous oxide emissions compared with a pasture control
• Comprehensive data on nitrous oxide emissions and nitrous oxide emission factors, and the likely source of these emissions collected over the period of the study

The supplier will deliver the following:
• Quarterly science reports outlining progress against the project activities and any issues arising. Note that elements of these reports will be used by MPI and the NZAGRC as inputs to the Alliance’s Livestock Research Group.
• By the end of the contract submit a minimum of one paper to an international peer-reviewed journal outlining the results from the studies undertaken along with an initial assessment of the consequences that full inversion tillage has for nitrous oxide emissions.
• Within 15 working days of the end of the contract submit a final report that summarises the achievements of the project and assesses its successes and failures and makes recommendations as to next steps.
