Mitigation of nitrous oxide emissions using a nitrification inhibitor, alternative pasture and forage plants and gibberellic acid
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 ...
Getting the most from your dairy support land - tips for allocating winter forages
(South Island Dairy Event (SIDE)., 2008-06)
As dairy farming businesses expand and the push for productivity improvement continues there is increasing pressure to maximise milksolids production from the milking platform. A consequence of this production drive is the ...
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.
¹⁵N recoveries from ruminant urine patches on three forage types
(Springer Verlag on behalf of the Royal Netherlands Society of Agricultural Science, 2017-05-17)
Background and aims: ¹⁵Nitrogen balances are useful tools to increase our understanding of soil N processes and the efficiency of plants in taking up animal urine-N. This study aimed to investigate the effect of forage ...
Suppression of vulpia and goose grass in dryland pastures through the choice of sown pasture species
(New Zealand Grassland Association., 2010)
Vulpia (Vulpia myuros) and goose grass (Bromus hordeaceus) are common annual grass weeds throughout New Zealand in dryland pastures. They compete with sown species, suppressing pasture production and livestock performance. ...
Ruminant urine patch nitrification and N₂O flux: Effects of urine aucubin rate in a laboratory trial
(Taylor & Francis on behalf of Royal Society of New Zealand, 2019-06-10)
Livestock urine deposition onto grazed New Zealand pastures drives soil nitrous oxide (N₂O) emissions. Urine patch N₂O emissions can be reduced by inhibiting nitrification, a key urine patch nitrogen (N) transformation ...
Control of gorse (Ulex europaeus) in dryland pasture converted from Pinus radiata forest
(New Zealand Plant Protection Society, 2007-09-24)
The effect of crop sequence, pasture species mixture and nitrogen fertiliser on gorse establishment was monitored over 23 months in land converted from pine forest to a dryland sheep pasture. There were fewer gorse plants in ...
Body weight of dairy heifers is positively associated with reproduction and stayability
(American Dairy Science Association, 2020-02-26)
This study investigated the relationships between body weight (BW) and stayability, and BW and calving pattern, of 189,936 New Zealand dairy heifers. Heifers were classified into 5 breed groups: Holstein-Friesian (F), ...
Infrequent dietary supplementation feeding in beef cattle: Animal responses and factors affecting its success
(CAB International, 2020-06-09)
Infrequent supplementation (IS; i.e., feeding supplement to animals at frequency less than daily) as opposed to frequent (i.e., daily) could be used as a management tool to improve economic returns of extensive beef ...
Survey of management practices of dairy cows grazing kale in Canterbury
(New Zealand Grassland Association., 2008)
Many dairy cows, particularly in southern New Zealand have kale (Brassica olercaea) as a major component of their winter diet. Anecdotal evidence suggests variable results in cow body condition are achieved when kale is used ...
