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, ...
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 ...
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 ...
Management zone delineation in arable crop systems
(Fertilizer and Lime Research Centre, 2015)
Management Zone Delineation (MZD) could be of increasing importance for its economic and environmental benefits through varying rates of crop inputs to meet site-specific demands across individual ...
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, ...
Active light sensing of canopies in crop management: Pastures and arable crops
(Fertilizer and Lime Research Centre, 2015-02)
A field spectrometer with an active light source was tested as a potential canopy sensor for dairy pastures (‘TEC-5’, YARA). To study the applicability of the sensor on pasture for the intensive radiation conditions of NZ ...
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, ...
Developing a comprehensive Drift Reduction Technology risk assessment scheme
(De Gruyter Open on behalf of the Polish Academy of Sciences, Institute of Plant Protection - National Research Institute and the Polish Society of Plant Protection, Committee of Plant Protection, 2014-01-01)
Drift Reduction Technologies (DRTs) are becoming increasingly important for improving spray applications in many countries including New Zealand (NZ). Although there is a growing database on the performance of DRTs, there ...
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 ...
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 ...
