Peat soil properties and seasonal surface elevation changes of drained Waikato peatlands
(The University of Waikato, 2022)Peat surface oscillation (PSO) is the elastic seasonal change in peatland surface elevation that occurs as a response to changes in the water balance, and is an important self-regulating behaviour for sustaining hydrological ... -
Flows of water and nutrients to Lake Tarawera and connected lakes
(The University of Waikato, 2022)Lake Tarawera is a large, deep lake located within the Taupō Volcanic zone, 12 km south-east of Rotorua. Seven smaller lakes within the “Greater Lake Tarawera catchment” (Lakes Ōkareka, Ōkaro, Ōkataina, Rerewhakaaitu, ... -
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 ...
