Autumn nitrogen effects on perrenial ryegrass (Lolium perenne L.) and cocksfoot (Dactylis glomerata L.) pastures in dryland Canterbury.
(Lincoln University, 2012)
This research examined the effects of autumn nitrogen application at five rates (0, 50, 100, 200 and 400 kg N/ha) on dry matter production and the nutritive value of cocksfoot and perennial ryegrass, and the subterranean ...
Dry matter production of Lucerne (Medicago sativa L.) under rotational grazing at Ashley Dene
(Lincoln University, 2012)
Lucerne (Medicago sativa L.) is a key legume for dryland farming systems in New Zealand. This experiment compared dry matter production of seven lucerne cultivars across six paddocks in a rotationally grazed system. ...
Crossing the species barrier: investigating vertical transmission of a fungal endophyte from tall fescue within a novel ryegrass association
(Lincoln University, 2017-02-28)
Many Poaceae grasses form a symbiosis with Epichloë fungal endophytes. Initially a serious problem in agriculture due to their production of alkaloids toxic to livestock, endophyte strains were identified that were less ...
An investigation of the incorporation of a standoff facility with the grazing of fodder beet in a Canterbury dairy wintering system
(Lincoln University, 2014)
Dairy farmers are under scrutiny for the negative effect their farming operations have on the environment, particularly in regard to nitrate leaching. The National Policy Statement for Freshwater has directed regional ...
Dry matter production and water use of dryland cocksfoot/lupin and lucerne pastures in the third year after establishment
(Lincoln University, 2017-11-14)
Cocksfoot (Dactylis glomerata) is a preferred grass option for dryland pastures on high country farms in the South Island of New Zealand. However, increasing the productivity of cocksfoot based pastures with legumes is ...
The influence of ryegrass sowing rates and nitrogen fertiliser on white clover establishment : A dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science with Honours at Lincoln University
(Lincoln University, 2004)
Perennial ryegrass (Lolium perenne L.) pastures were sown on 19 February at four sowing rates (0, 5, 10, 20 kg/ha) with four rates of nitrogen fertiliser (0, 20, 40, 80 kgN/ha). White clover (Trifolium repens L.) was sown ...
Effect of using a catch crop to reduce nitrate leaching losses from winter grazed fodder beet soil
(Lincoln University, 2017-11-13)
Grazing of winter forage crops such as fodder beet (Beta vulgaris L.) and kale (Brassica oleracea L.) is a common management option for increasing winter feed supply on New Zealand farms. This practice is most often ...
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, ...
Urine patch area coverage of an intensively stocked dairy pasture
(International Union of Soil Science, 2010-08)
The urine patch of the grazing cow has been identified as the key source of N loss from pasture-based dairy
systems. Although critical to N modelling, quantitative data on the annual area coverage of urine patches in
pastures ...
Confirmation of co-denitrification in grazed grassland
(Nature Publishing Group, 2015-11-30)
Pasture-based livestock systems are often associated with losses of reactive forms of nitrogen (N) to the environment. Research has focused on losses to air and water due to the health, economic and environmental impacts ...
