Lime, phosphorus and sulphur response of French serradella (Ornithopus sativus) grown in an acid upland soil
(International Scientific Publications, 2014-06-01)
Soil acidity severely restricts legume persistence and growth in grazed upland agriculture in New Zealand. An alternative and potentially acid tolerant forage legume, French serradella (Ornithopus sativus), was examined ...
Nutrient cycles under grazing
(Lincoln College, University of Canterbury, 1963)
The aim of this dissertation on is to construct biological cycles for major and important minor elements, starting at the soil, tracing the nutrients through the plant and animal and finally back to the soil animal droppings. ...
The development and growth of annual clovers for use in dryland pasture
(Lincoln University, 2013)
A series of field and controlled environment experiments aimed to quantify development and growth characteristics of arrowleaf, balansa, gland and Persian clovers for introduction to New Zealand dryland pastures. Thermal ...
Nutrient recycling using biowastes from diverse sources
(Lincoln University, 2018)
Phosphorus is a limiting nutrient in crop growth and thus widely used as an agricultural fertiliser. It cannot be substituted by another element, nor newly synthesized. Hence, global food production is ultimately dependent ...
Spatial aspects of bumble bee (Bombus spp. Apidae) foraging in farm landscapes
(Lincoln University, 1997)
Bumble bees (Bombus spp.: Apidae) are valuable pollinators of many crop and wildflower species. However, in some situations their potential is limited. Evaluation of, and management to improve bumble bee efficacy should ...
Environmental drivers of bulb production in brassicas
(Lincoln University, 2013)
Bulb brassicas are used as supplementary feed in intensive pastures systems. However, there is a lack of quantitative data to define their growth and development. This has limited the creation and use of prediction models ...
Characterising the pathogenicity of Cylindrocarpon pauciseptatum associated with black foot disease on grapevines
(Lincoln University, 2014)
Black-foot disease caused by Cylindrocarpon/Ilyonectria species is a widespread disease of grapevines. In a 2005 survey of symptomatic plants in New Zealand, 95% of the pathogenic species recovered were “Cylindrocarpon” ...
A study of the nutritive value of untopdressed hill country pastures
(Canterbury Agricultural College, University of New Zealand, 1951)
Pastures provide the natural food supply of grazing animals and are the raw materials for the world's wool, meat and dairying industries. In an effort to increase livestock production, research workers have been developing ...
An economic evaluation of the Masagana 99 rice production programme of the Philippines
(Lincoln College, University of Canterbury, 1979)
This study is an ex post analysis of the economic merit of Masagana 99 as a public investment. The analysis was carried out at the national and regional levels for the period CY 1973-74 to 1976-77. The economic returns ...
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 ...
