Wheat nitrogen fertilisation effects on the performance of the cereal aphid Metopolophium dirhodum
(MDPI AG, 2012-02-09)
The effects of five rates of nitrogen fertiliser applications on the performance of the cereal aphid Metopolophium dirhodum on winter wheat, within the range of rates recommended for UK crops, were investigated over two ...
Potential pasture nitrogen concentrations and uptake from autumn or spring applied cow urine and DCD under field conditions
(MDPI, 2016-06)
Nitrogen (N) cycling and losses in grazed grassland are strongly driven by urine N deposition by grazing ruminants. The objective of this study was to quantify pasture N concentrations, yield and N uptake following autumn ...
Tolerance of newly sown cocksfoot-clover pastures to the herbicide imazethapyr
(New Zealand Grassland Association, 2017)
In New Zealand, subterranean clover is recommended as a companion legume in mixed swards, particularly in dryland cocksfoot-based pastures. However, establishment of cocksfoot is slower than perennial ryegrass and therefore ...
Calculating “Hydrothermal time” to quantify seed germination of tall fescue
(NZGA, 2016)
The objective of this study was to quantify the combined effects of temperature and moisture on germination of tall fescue seed. Seeds were incubated for up to 50 days at a range of constant temperatures (5-35ºC) and ...
Maximising the subterranean clover content on a summer-dry Wairarapa hill-country farm through grazing management
(New Zealand Grassland Association, 2019-11-04)
Tokaroa Farm is a 608-ha sheep and beef farm, in the Wairarapa. Paddock slopes range from flat to steep (>25°) with a predominance of gentler north facing slopes and steeper south facing slopes. Annual rainfall is 810 mm ...
Assessing the ability of a stationary pasture height sensing device to estimate pasture growth and biomass
(New Zealand Grassland Association, 2019-11-04)
Good pasture management requires an accurate knowledge of whole-farm feedbase, yet most systems for measuring pasture growth are manually operated and time consuming. A newly developed pasture-measuring device enables ...
Integration of crop and dairy farms
(New Zealand Institute of Primary Industry Management (NZIPIM), 2014-06)
In this article we report on case study investigations in 2012 of seven farm businesses in mid-Canterbury. These are part of a further evolution within some of the region’s dairy industry towards the integration of crop ...
Impact of different tree species on soil phosphorus immediately following grassland afforestation
(Sociedad Chilena de la Ciencia del Suelo (Chilean Society of Soil Science), 2016-06)
Previous studies have revealed that significant changes in soil phosphorus (P) occurred as a consequence of grassland afforestation, although when these changes occurred and the influence of different tree species remains ...
Soil biodiversity and biogeochemical function in managed ecosystems
(CSIRO, 2020-01)
A complex combination of environmental, biological, chemical, and physical properties and processes determine soil biodiversity and its relationship to biogeochemical functions and ecosystem services. Vegetation, land-use, ...
Fertiliser-coating technology to improve the efficiency of copper uptake in pastures
(Fertilizer and Lime Research Centre, Massey University, 2018)
Current practice for trace element (TE) application is to admix granular trace elements in with macro-elemental fertilisers. Although the correct rate of trace elements per hectare can be applied, the distribution of the ...
