Italian ryegrass swards reduce N leaching via greater N uptake and lower drainage over perennial ryegrass cultivars varying in cool season growth rates
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2018-02-04)
Pasture mitigation strategies are needed to reduce the negative effects of nitrate (NO₃⁻) leaching from intensive pastoral livestock production systems. We explored the capability of pasture grasses with different cool ...
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 ...
Nitrate leaching losses are lower from ryegrass/white clover forages containing plantain than from ryegrass/white clover forages under different irrigation
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2018-04-18)
The aim of this research was to assess the potential of using perennial ryegrass (Lolium perenne) and white clover (Trifolium repens) forages containing plantain (Plantago lanceolata L.) (PRGWC + Plantain) to mitigate ...
Production, profit and nitrogen flows in irrigated dairy systems representing different industry development pathways: The Pastoral 21 experience in Canterbury
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2020-08-26)
Future development pathways for irrigated dairy farms in Canterbury operating under stricter nitrogen (N) loss limits were compared in two farmlets over four years. One represented the traditional pathway of intensification ...
Effect of two irrigation rates on nitrate leaching from diverse or standard forages receiving spring deposited urine
(Royal Society of New Zealand and Taylor & Francis, 2017-12-20)
The effect of two irrigation rates on nitrogen (N) harvested by diverse and standard forages, and the subsequent effect on nitrate (NO₃⁻) leaching losses from spring deposited urine was investigated. An experiment, using ...
Sowing a winter catch crop can reduce nitrate leaching losses from winter-applied urine under simulated forage grazing: A lysimeter study
(Wiley on behalf of the British Society of Soil Science, 2016-09)
Grazing of winter forage crops is a common management option used in the dairy industry of New Zealand, particularly in the South Island, where they are used to feed nonlactating, pregnant dairy cows prior to calving. ...
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 ...
