The spatial coverage of dairy cattle urine patches in an intensively grazed pasture system
(Cambridge University Press, 2010-12-23)
Accurate field data on the paddock area affected by cow urine depositions are critical to the estimation and modelling of nitrogen (N) losses and N management in grazed pasture systems. A new technique
using survey-grade ...
The effect of urinary nitrogen loading rate and a nitrification inhibitor on nitrous oxide emissions from a temperate grassland soil
(Cambridge University Press, 2014-12)
Nitrous oxide (N₂O) emissions associated with urine nitrogen (N) deposition during grazing are a major component of greenhouse gas emissions from domestic livestock. The present study investigated the relationship between ...
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 ...
Measuring excreta patch distribution in grazed pasture through low-cost image analysis
(Wiley on behalf of the British Grassland Society and the European Grassland Federation, 2013-09)
Nutrient losses from grazed pasture are an important non-point source of water pollution. The distribution of animal urine patches on pasture is an important factor in determining nitrate losses and influencing pasture ...
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 ...
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 ...
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 ...
Dicyandiamide (DCD) effect on nitrous oxide emissions, nitrate leaching and pasture yield in Canterbury, New Zealand
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2014)
© 2014 The Royal Society of New Zealand. A 3-year study was carried out in Canterbury, New Zealand, to determine the effect of a nitrification inhibitor dicyandiamide (DCD) on N₂O emissions, nitrate (NO₃⁻) leaching and ...
