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. ...
Phosphorus response and efficiency of four adventive annual clovers grown in a New Zealand high country soil under glasshouse conditions
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2013)
Maintaining and increasing legume abundance is a critical component of pastoral intensification, increasing nitrogen inputs to nitrogen deficient New Zealand high and hill country pastures and improving feed quality. ...
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 ...
Influence of plant growth and root architecture of Italian ryegrass (Lolium multiflorum) and tall fescue (Festuca arundinacea) on N recovery during winter
(John Wiley & Sons Ltd, 2015-12)
© 2015 John Wiley & Sons Ltd. Nitrate (NO₃⁻) leaching is an environmental and health concern. In grazed pasture systems, NO₃⁻ leaching primarily occurs beneath animal urine patch areas due to high nitrogen (N) loading and ...
Grazing and soil fertility effect on naturalized annual clover species in New Zealand high country
(Elsevier on behalf of the Society for Range Management, 2016-11)
With a view to increasing rangeland pasture legume abundance, the herbage biomass and seedling recruitment of four New Zealand naturalized annual clover species (haresfoot clover Trifolium arvense L., suckling clover T. ...
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 ...
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 ...
