Increasing the quantity of carbon stored in agricultural soils has the potential to offset emissions of greenhouse gases to the atmosphere, while soil carbon losses would further add to those emissions.
However, realising this mitigation potential is technically challenging when soil carbon stocks are already high (as they are in New Zealand), potential changes in soil carbon are small and spatial variability is high.
The current NZAGRC programme has three distinct components:
(1) testing specific management practices that may increase the long term soil carbon store in field situations;
(2) developing and using models to predict how a range of management practices may influence long and short tem soil carbon storage; and
(3) identifying those factors that influence the stability of current or newly added soil carbon.
We have also supported international work to map on farm soil carbon and will participate in the international research programme CIRCASA.

KuDos to Aaron Wall of Waikato University
University of Waikato technician, and a pivotal player in the NZAGRC-funded soil carbon programme, Aaron Wall was a winner in last month’s 2015 KuDos Hamilton Science Excellence Awards.
The School of Science Technical Officer picked up the top award in the Hill Laboratories Laboratory Technologist Award section.
Aaron spends much of his time expertly managing the Troughton farm site for the NZAGRC programme. Additionally, he also manages the access to the site for related research by AgResearch, Plant and Food Research and Landcare Research. His excellent relationship with the farm owners, and unsung heros of the whole operation, Ben and Sarah, enables everything to run smoothly.
On top of overseeing what goes on and when at the Troughton site, Aaron is a key part of the NZAGRC research team. He has made considerable novel advances in analysis of eddy covariance data, collation of non-CO2 data and pushed the team to collect additional data that are now proving to be crucial. Aaron is able to bring together deeply technical analysis tools with on-farm understanding and his colleagues feel extremely lucky to have him in their team.
Well done Aaron!
