Crop recovery of labelled -15N urinary nitrogen following simulated winter forage grazing
(2015)
In Canterbury, New Zealand, sowing a spring brassica crop is a popular option for dairy cow wintering management providing feed at a time when reserves are low. However, the intensive winter forage grazing system has a ...
Dry matter intake and body condition score change of dairy cows grazing fodder beet, kale and kale-oat forage systems in winter
(NZGA, 2014)
Crop dry matter (DM) yield, DM utilisation and body condition score (BCS) of dairy cows were measured over two winters on an irrigated stony, free-draining Balmoral soil for three crop grazing systems: fodder beet (FB); ...
Can a winter-sown catch crop reduce nitrate leaching losses after winter forage grazing?
(Fertilizer and Lime Research Centre, 2016)
Direct grazing of winter forage crops to feed non-lactating, pregnant dairy cows prior to calving is a common management practice in the New Zealand South Island. However, the high crop yields per hectare grazed, combined ...
What is the 'effective area' of a urine patch?
(2015-09)
Cattle urine patches are widely regarded as a key contributor to nitrate leaching in pastoral systems because the N loading (up to 1000 kg N per hectare) in a single urine patch is far in excess of what the ...
The effect of DCD on nitrogen losses from sheep urine patches applied to lysimeters in autumn
(New Zealand Grassland Association, 2010)
The intensification of modern pastoral agriculture
has increased the risk of environmental degradation.
The use of nitrification inhibitor technology has been
shown to reduce nitrate (NO₃
⁻) leaching losses and
nitrous ...
Clean and green with 'eco-n'
(South Island Dairy Event (SIDE)., 2004-06)
Lincoln University and Ravensdown Fertiliser Co-operative have developed a new soil
treatment technology, called 'eco-n' technology, that can reduce the environmental impacts of dairy farming and at the same time help ...
Urine patch area coverage of an intensively stocked dairy pasture
(Lincoln University., 2010-08)
The objective of this study was to develop a new method to quantify seasonal and annual urine patch area coverage under an intensive dairy farming system.
