Can oxygen stable isotopes be used to track precipitation moisture
(Elsevier, 2015-08-14)Variations in the isotopic composition of precipitation are determined by fractionation processes which occur during temperature- and humidity-dependent phase changes associated with evaporation and condensation. Oxygen ... -
Carbon leaching from undisturbed soil cores treated with dairy cow urine
(CSIRO, 2012)Solubilisation of soil carbon (C) under cow urine patches may lead to losses of soil C by priming or leaching. We investigated the solubilisation and bioavailability of soil C in undisturbed pasture soil treated with urine. ... -
Changes in natural ¹⁵n abundance in pastoral soils receiving differing amounts of superphosphate fertilizer and irrigation for 50 years
(Soil Science Society of American, 2013)Intensification of pastoral agriculture has led to increased N losses to the wider environment. This has led to an emphasis on improving our understanding of soil N dynamics, and development of management practices which ... -
A comparison of different approaches for measuring denitrification rates in a nitrate removing bioreactor
(Elsevier, 2011)Denitrifying woodchip bioreactors (denitrification beds) are increasingly used to remove excess nitrate (NO₃⁻) from point-sources such as wastewater effluent or subsurface drains from agricultural fields. NO₃⁻ removal in ... -

Identifying control points of excessive nitrate load in a pastoral catchment to support lake management
(The University of Waikato, 2023)Excessive leaching of nitrogen (N) from pasture grazing catchments continues to challenge sustainable freshwater and lake management. However, managing contaminant export from diffuse agricultural sources is difficult due ... -
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, ... -
Variation in nitrate sources and delivery in space and time within the 389 ha Lake Okaro catchment
(The University of Waikato, 2020)The eutrophication of surface water is a global issue, with excessive nitrate concentrations reducing water quality and affecting water supplies, ecosystem health and its recreational use. In New Zealand, the degradation ... -
Seasonal and spatial patterns in nitrogen cycling and food web interactions in Lake Taupō New Zealand
(The University of Waikato, 2018)Lakes with high water quality and low productivity, commonly referred to as ‘oligotrophic’, are often viewed as relatively pristine and highly aesthetic ecosystems, but may still require management of nutrient inputs and ... -
Soil carbon loss under pasture and pine: Responses to urine addition
(University of Waikato, 2012)There have been reports of losses of soil carbon (C) in New Zealand pastures under dairy grazing. Acceleration of mineralisation or leaching of soil C following urine deposition may decrease soil C. However, little ...
