Specific genotypes of plantain (Plantago lanceolata) vary in their impact on sheep urine volume and nitrification in the urine patch
(New Zealand Grassland Association, 2018-11-13)
Plantain has the potential to reduce nitrate leaching through a number of mechanisms. In an indoor study, sheep were offered either perennial ryegrass or different plantain genotypes while aiming to achieve similar dry ...
Metabolisable energy concentration in perennial ryegrass pastures: Multi-site analysis of effects of cultivar, nitrogen fertiliser and white clover content
(New Zealand Grassland Association, 2018-11-13)
To include metabolisable energy (ME) as a nutritive value factor for ryegrasses in the Forage Value Index (FVI) requires data for New Zealand cultivars on the effects of environmental and management ...
Persistence of ryegrass, tall fescue and cocksfoot following sequential annual sowings: Pasture yield, composition and density in 3 establishment years under sheep grazing in Canterbury
(New Zealand Grassland Association, 2018-11-13)
A long-term pasture persistence trial, consisting of repeated annual sowings, commenced in Canterbury in 2015 and is planned to continue until 2024. Preliminary results of the first 3 years sowings are reported. ...
The effect of optimum vs deficit irrigation on plant nitrogen uptake and nitrate leaching loss from soil
(Fertilizer and Lime Research Centre, Massey University, 2016)
Nitrate (NO₃⁻) leaching, associated with urine nitrogen (N) deposition during grazing is recognised as a significant environmental problem. In this study it was hypothesised that optimum irrigation could increase plant ...
In vitro fermentation characteristics of ryegrass-white clover sward containing different proportions of chicory
(New Zealand Society of Animal Production, 2017)
Chicory (Cichorum intybus) is a deep-rooted grazeable forage used to overcome production and nutritive value shortfalls of perennial ryegrass (Loliun perenne) and white clover (Trifolium repens) swards during summer drought ...
Influence of the endophyte fungus in ryegrass on grazing preference by sheep
(Lincoln University, 1990)
Animal productivity may be enhanced through greater intake associated with the use of preferred pasture species provided they are of high nutritional value. Grazing preference by ewe hoggets was investigated in three grazing ...
Can topdressing with salt increase oversowing success and pasture quality on steep, south facing slopes in hill country pastures?
(New Zealand Grassland Association, 2006)
Two experiments were conducted in sodium deficient
(<0.03% Na in DM) pastures on steep, south facing
slopes at Mt Grand, Hawea, Central Otago (600 m.a.s.l),
to determine the effect of the application of coarse salt
(NaCl) ...
Can salt increase oversowing success on south facing hill country?
(Lincoln University, Agriculture Group., 2006-11)
Salt application is a tool for pasture management and improvement in the hill/high country that could be used together with other methods such as herbicides, seeding, sub-division, grazing management and fertiliser.
Mitigation of nitrous oxide emissions using a nitrification inhibitor, alternative pasture and forage plants and gibberellic acid
(SLU, 2016-06)
In grazed pastures, nitrous oxide (N₂O), the potent greenhouse gas, is mostly emitted from animal excreta, particularly animal urine-N retuned to the soil during grazing. N₂O is produced in the soil through nitrification ...
Prediction of urinary output from pasture-fed dairy cows
(2012)
Prediction equations using easily acquired measurements could offer an estimate of urinary nitrogen output (UNO), therein helping to refine nutrient management on dairy farms. However, there is little evidence regarding ...
