Causes of leaf reddening in subterranean clover cultivars
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2020-04-30)
Subterranean clover (Trifolium subterraneum L.) is an important legume in dryland hill pastures in New Zealand. In this environment plants adapt to low temperatures (<10°C) through a series of physiological mechanisms, ...
There is no relationship between plasma amino acid concentration and urinary nitrogen concentration in heifers fed plantain or ryegrass
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2020-04-20)
The objective of this study was to investigate the relationship between plasma amino acid (AA) concentration and urinary nitrogen (N) concentration of dairy heifers offered cut plantain or perennial ryegrass-white clover ...
Animal and forage responses on lucerne (Medicago sativa L.) pastures under contrasting grazing managements in a temperate climate
(Wiley on behalf of the British Grassland Society and the European Grassland Federation, 2020-06)
This study determined the impact of a change in grazing system on beef production from lucerne pastures in Argentina. One system (T500) used the traditional recommendation to commence grazing in spring when lucerne was ...
Livestock in evolving foodscapes and thoughtscapes
(Frontiers Media S.A., 2020-07-14)
Humanity’s main societal and epistemic transitions also mirror changes in its approach to the food system. This particularly holds true for human–animal interactions and the consumption of animal source foods (red meat ...
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 ...
Seventy years of data from the world’s longest grazed and irrigated pasture trials
(Springer Nature, 2021-02-10)
Pastures are the most widespread land use, globally. The Winchmore trials were established in 1948–1949 in Canterbury, New Zealand and examined either different rates of phosphorus (P) fertiliser on the same irrigation ...
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 ...
Factors influencing fertiliser and lime decisions on South Island high- and hill-country farms
(New Zealand Grassland Association, 2020-09-09)
Highlights • Fertiliser and lime decisions by high-and hill-country farmers directly impact on their farm performance, but the factors influencing these decisions are not well understood. • Factors influencing South Island ...
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 ...
Impacts of phosphogypsum, soluble fertilizer and lime amendment of acid soils on the bioavailability of phosphorus and sulphur under lucerne (Medicago sativa)
(MDPI, 2020-07)
Legumes play critical dual roles in grazed grassland ecosystems; providing nitrogen inputs and high-quality feed for grazing livestock. However, many species fail to persist in acidic, low fertility soils. A glasshouse ...
