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, ...
The Proceedings of the Lincoln College Farmers' Conference 1969
(Lincoln College (Lincoln, N.Z.)., 1969)
The Lincoln College Farmers’ Conference was an annual event held over a period of thirty six years from 1951 to 1986. It was a forum for farmers with participation in the early years by district nomination. The strength ...
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 ...
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, ...
The effect of optimum vs deficit irrigation on plant nitrogen uptake and nitrate leaching loss from soil
(Fertilizer and Lime Research Centre, Massey University, 2016)
Nitrate (NO₃⁻) leaching, associated with urine nitrogen (N) deposition during grazing is recognised as a significant environmental problem. In this study it was hypothesised that optimum irrigation could increase plant ...
Metabolisable energy concentration in perennial ryegrass pastures: Multi-site analysis of effects of cultivar, nitrogen fertiliser and white clover content
(New Zealand Grassland Association, 2018-11-13)
To include metabolisable energy (ME) as a nutritive value factor for ryegrasses in the Forage Value Index (FVI) requires data for New Zealand cultivars on the effects of environmental and management ...
European experience with variable rate fertilizer application (VRA)
(Fertilizer and Lime Research Centre, 2013-02)
Modern fertilization strategies handle the amount of applied fertilizer according to the demands of crops and paddocks. Besides agronomic and economic reasons increasingly also environmental sensitivities (soils, water-bodies, ...
Control of gorse (Ulex europaeus) in dryland pasture converted from Pinus radiata forest
(New Zealand Plant Protection Society, 2007-09-24)
The effect of crop sequence, pasture species mixture and nitrogen fertiliser
on gorse establishment was monitored over 23 months in land converted
from pine forest to a dryland sheep pasture. There were fewer gorse plants
in ...
Yield and composition of lucerne stands in Central Otago after different winter grazing and weed control treatments
The effect of grazing date and time of spraying with a glyphosate/atrazine herbicide combination on a three year-old lucerne stand was studied on-farm in Central Otago. Total annual dry matter (DM) yield was highest in the ...
Plantain silage quality under variable management practices
(New Zealand Grassland Association, 2018-11-17)
Two studies investigated the effect of regrowth and additives on preservation and quality of plantain ensiled in spring using a micro-silage technique. Study 1 compared the effect of regrowth at four (4L), five (5L) or six ...
