Characterising the temperature dependence of anaerobic CH₄ and CO₂ production from intact and drained New Zealand peatlands
(The University of Waikato, 2021)Understanding the temperature response of anaerobic microbial processes in wetlands is important in determining consequences for carbon dynamics and the production of methane (CH₄) under climate warming scenarios. Natural ... -
'Hass' avocado tree water use and the effects of water stress on fruit development
(The University of Waikato, 2020)‘Hass’ avocado tree water use and the effects of water deficits on fruit development were assessed in New Zealand from 2017 to 2019. Avocado tree water use was quantified by sap flow measurement and the soil water balance ... -
The impact of maize silage production and supplementary feed use on the carbon balance of New Zealand dairy farms
(The University of Waikato, 2021)Globally, agriculture contributes 10-12% to anthropogenic greenhouse gas (GHG) emissions. Consequently, mitigation of agricultural GHGs has taken on increased importance, particularly in countries like New Zealand where ... -
Paddock scale nitrous oxide emissions from intensively grazed pasture: Quantification and mitigation
(The University of Waikato, 2021)Agricultural soils are the main contributor to global emissions of the potent greenhouse gas nitrous oxide (N₂O) to the atmosphere. Nitrous oxide can absorb and transform radiative energy emitted from the sun to earth into ... -
Fluxes of carbon dioxide and water vapour at a Waikato peat bog
(The University of Waikato, 2003)New Zealand wetlands are threatened entities and the remaining 15% of pre-European freshwater wetlands are important refuges for plant and animal species, while also providing historical information on past environmental ...
