Reduction of nitrogen losses by manipulating carbon inputs and pasture composition : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2020)
The nitrogen (N) cycle is very important to New Zealand agriculture, with N being a key nutrient needed for plant growth. However, there are major environmental concerns relating to the loss of N from agricultural systems. ...
Understanding water losses from irrigated pastures on loess-derived hillslopes
(New Zealand Grassland Association, 2020-09-09)
Irrigation is likely to increase water losses from hillslopes, particularly on loess-derived soils with impeded drainage. This is important as irrigation of these soils in New Zealand is increasing. A field site was ...
Soil biodiversity and biogeochemical function in managed ecosystems
(CSIRO, 2020-01)
A complex combination of environmental, biological, chemical, and physical properties and processes determine soil biodiversity and its relationship to biogeochemical functions and ecosystem services. Vegetation, land-use, ...
Potential profit gains from improving pasture productivity on New Zealand South Island high-country farms
(New Zealand Grassland Association, 2020-09-09)
Soil acidity combined with low levels of key nutrients on New Zealand hill-country farms are limiting factors for legume establishment/growth. However, legumes are a critical component of these farms as they provide nitrogen ...
Functional traits, morphology, and herbage production of vernalised and non-vernalised chicory cv. Choice (Cichorium intybus l.) in response to defoliation frequency and height
(MDPI, 2020-05)
Chicory (Cichorium intybus L.) used in pastoral systems has the attributes required of a forage species to reduce animal urinary nitrogen loading to soil, increase milk production, and enhance milk fatty acid profile to ...
Yield of subterranean clover after post-emergence herbicide application for broadleaf weed control
(New Zealand Grassland Association (NZGA), 2020-09-09)
A field experiment was established in Lincoln, Canterbury in autumn 2018 to evaluate the effect of acetolactate synthase (ALS) inhibiting herbicides on subterranean (sub) clover. Two herbicides, imazethapyr and flumetsulam, ...
Grazing dairy cows with low milk urea nitrogen breeding values excrete less urinary urea nitrogen
(Elsevier, 2020-10-15)
There is an increasing pressure on temperate pastoral dairy production systems to reduce environmental impacts, coming from the inefficient use of N by cows in the form of excessive urinary N excretion and subsequent N ...
