The growth of grasses and legumes on a sequence of acid soils as affected by liming and phosphate fertiliser
(Lincoln College, University of Canterbury, 1974)
The causes of differential growth of lucerne, lotus, ryegrass and brown top on a range of three acid soils were investigated by means of pot trials carried out in the glasshouse.
Of the four species, lucerne was affected ...
Development of mechanistic energy balance models for grassland
(Lincoln University, 1996)
Grasslands are responsible for a significant percentage of the world's food supplies and, due to their large geographical extent, have an important influence on global climate. Major determinants of grassland productivity ...
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, ...
Fertilizer and stocking rates on two King Country soils
(New Zealand Grassland Association., 1973)
Parent materials such as volcanic ash and sedimentary siltstone
and sandstone form soils which differ markedly in their physical
and chemical properties. In stocking x fertilizer rate trials on
two families of soils, ...
Phosphorus response and efficiency of 12 novel dryland legume species on an acid high country soil
(Fertilizer and Lime Research Centre, Massey University, 2012-02)
High country soils are typically acidic and have low fertility compared with intensive high fertility low land systems. Pasture legumes commonly used in New Zealand perform poorly in these environments. The optimum soil P ...
Role of mixed herb leys in New Zealand organic cropping systems : a dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science (Honours) in the Lincoln University [i.e. College]
(Lincoln College, University of Canterbury, 1989)
Above ground dry matter production, sward composition, and herbage mineral levels were measured from three ley mixtures sown on a Wakanui silt loam, Lincoln College, Canterbury. Additionally soil fertility (exchangeable ...
The fate of urine nitrogen: A grassland lysimeter study in Ireland
(Fertilizer and Lime Research Centre, 2014-02)
In grazed pasture systems, the nitrogen (N) contained in a cattle urine patch may be up to 1200 kg N ha⁻¹. The majority of this N is in excess of plant requirements and is vulnerable to environmental loss. In this study, ...
Liming effects on legume production and phosphorus availability in acid South Island hill and high country soils : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2019)
There is large potential for widespread development and increased production in South Island hill and high country by increasing legume production. Despite regular past applications of superphosphate fertiliser, current ...
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 ...
Quantifying perennial ryegrass (Lolium perenne L.) and white clover (Trifolium repens L.) seed germination responses to water potential and temperature with a hydrothermal time model
(Taylor & Francis and the Royal Society of New Zealand, 2019-06-03)
In New Zealand, a commonly sown pasture combination is perennial ryegrass with white clover. The hydrothermal time model (HTT) was used to quantify germination under different temperature (T) and water potential (WP) ...
