Inverse modelling of New Zealand's carbon dioxide balance estimates a larger than expected carbon sink Open
Accurate national-scale greenhouse gas source and sink estimates are essential to track climate mitigation efforts. Inverse models can complement inventory-based approaches for emissions reporting by providing independent estimates underpi…

Litter arthropods display greater differences among locations than grass species in a temperate grassland Open
Grasslands comprise a significant portion of terrestrial ecosystems, contributing an estimated 20% of global carbon stores. Biomass is recycled in these systems by photodegradation, biotic decomposition, and through disturbances such as fi…

Evaluation of the potential for nine established and emerging interventions to reduce soil carbon losses and increase stocks in grazing systems: A case study for Aotearoa New Zealand Open
This article reviews nine soil carbon interventions to reduce soil carbon losses or increase stocks in grazing management systems, using their potential application in Aotearoa New Zealand (A‐NZ) as a case study. The interventions are clas…

Effects of dairy farming management practices on carbon balances in New Zealand’s grazed grasslands: Synthesis from 68 site-years Open
Globally, the soils underlying managed grasslands are an important reservoir of carbon (C), with the management of the land strongly influencing whether the soils gain, lose or maintain C. Further, improved grassland management, such as ro…

Bridge to the future: Important lessons from 20 years of ecosystem observations made by the OzFlux network Open
In 2020, the Australian and New Zealand flux research and monitoring network, OzFlux, celebrated its 20 th anniversary by reflecting on the lessons learned through two decades of ecosystem studies on global change biology. OzFlux is a netw…

Attributes of resilient pasture for achieving environmental outcomes at farm scale Open
Pasture resilience commonly refers to a pasture’s ability to withstand or rebound from pressures to maintain production and quality of sown species. We suggest that a broader definition of pasture resilience is needed that also includes en…
View article: Importance of resilient pastures for New Zealand’s agricultural soil carbon stocks
Importance of resilient pastures for New Zealand’s agricultural soil carbon stocks Open
New Zealand’s agricultural pastures contain significant soil carbon (C) stocks that are susceptible to change when impacted by management and natural processes (e.g., climate). Inputs of C to these pastoral soils is through photosynthetic …

Plantain as a GHG mitigation option: N2O, C and GHG balances from an intensively grazed New Zealand dairy pasture Open
<p>Agricultural greenhouse gas (GHG) emissions account for almost half of New Zealand’s total emissions, and therefore considerable attention has been given to identifying and testing mitigation options. At plot scale, plan…
View article: Modelling carbon fluxes from New Zealand&#8217;s pastoral agriculture
Modelling carbon fluxes from New Zealand’s pastoral agriculture Open
<p>Grasslands cover half of New Zealand’s land area, with much of it consisting of pastoral agriculture systems of varying intensity. Carbon fluxes from grazed pasture are thus a crucial part of the national carbon budget. …

A novel injection technique: using a field-based quantum cascade laser for the analysis of gas samples derived from static chambers Open
The development of fast-response analysers for the measurement of nitrous oxide (N2O) has resulted in exciting opportunities for new experimental techniques beyond commonly used static chambers and gas chromatography (GC) analysis. For exa…

Long-term feedbacks result in the recovery of the CO2 sink in a remnant peatland following water table lowering Open
<p>Peatland biological, physical and chemical properties change over time in response to the long-term water table position. Such changes complicate predicting the response of peatland carbon stocks to sustained drying. Here we use E…

Modelling carbon and water exchange of a grazed pasture in New Zealand constrained by eddy covariance measurements Open
We used two years of eddy covariance (EC) measurements collected over an intensively grazed dairy pasture to better understand the key drivers of changes in soil organic carbon stocks. Analysing grazing systems with EC measurements poses s…
