Influence of environmental factors on the abundance of naturalised annual clovers in the South Island hill and high country
(New Zealand Grassland Association., 2010)
The abundance of four naturalised annual clovers (striated, cluster, suckling, haresfoot) and two sown clovers (subterranean and white clover) was investigated in relation to topographical, soil fertility and management ...
Nitrogen uptake of 16 grass species under high N loading
(Lincoln University, 2011-09-26)
A study to quantify and examine the variability in N uptake capacities of 16 pasture grass species under high N loading.
Nitrogen uptake and leaching loss of thirteen temperate grass species under high N loading
(John Wiley and Sons Ltd, Inc., 2013-06)
The intensification of grazed pasture systems in New Zealand has resulted in increased nitrate (NO₃⁻) leaching and associated significant reductions in water quality, resulting from high N loading in the cow urine patch. ...
Productivity and seedling recruitment of naturalised annual clovers versus sown clovers Trifolium repens and Trifolium subterraneum
Naturalised annual clover (NAC) species (suckling clover, cluster clover, striated clover, and haresfoot clover) are commonly present to locally abundant in summer dry hill and high country areas where white and subterranean ...
Grazing preference of Merino sheep for naturalized annual clover species relative to commonly sown clover species
(John Wiley and Sons, Inc., 2016-06)
Selective grazing of white clover (Trifolium repens) over grass species in temperate pastures results in reduced clover abundance and availability over time. Within sheep- and cattle-grazed dryland (<800 mm annual rainfall) ...
Herbage dry-matter yield and nitrogen concentration of grass, legume and herb species grown at different nitrogen-fertiliser rates under irrigation
(CSIRO Publishing, 2017)
An important goal in dairy systems is to increase production while achieving environmental targets associated with lower nitrate leaching from soils. One approach is to identify forages that grow more at a given level of ...
Modelling: Effect of feeding plantain pasture to three different breeds of calf/heifer on weight gain and nitrogen leaching in Canterbury
(Taylor and Francis on behalf of the Royal Society of New Zealand, 2020)
Four levels of plantain (0%, 25%, 50% and 75% on DM basis) inclusion rate to ryegrass-clover pasture and three target heifer mature live weights, 444 kg (representing Jersey), 529 kg (Friesian), and 492 kg (cross bred ...
Seedling recruitment response of New Zealand-naturalised annual clovers to superphosphate fertiliser in summer dry high country grassland
(Organising Committee of the 17th Symposium of the European Grassland Federation 2013 and Agricultural University of Iceland (AUI), 2013)
Pasture legume presence in low-input, extensively-grazed grassland areas is vitally important for provision of nitrogen inputs and quality herbage. Traditionally sown legume species such as Trifolium repens lack longevity ...
The effect of four different pasture species compositions on nitrate leaching losses under high N loading
(Wiley on behalf of the British Society of Soil Science, 2014-03)
Nitrate (NO₃⁻) leaching can cause elevated concentrations of NO₃⁻-N in water, which can have adverse impacts on water quality and human health. In grazed pasture systems, most of the NO₃⁻-N leaching occurs beneath animal ...
Sulphur and lime response of four adventive annual clovers grown in a New Zealand high country soil under glasshouse conditions
(Taylor and Francis on behalf of the Royal Society of New Zealand, 2012-03)
Adventive annual clovers play a critical role in nitrogen (N) cycling and feed quality in extensive summer-dry hill country, where traditionally sown white and subterranean clovers often fail to persist. However, very ...
