Phosphorus response and efficiency of 12 novel dryland legume species on an acid high country soil
(Fertilizer and Lime Research Centre, Massey University, 2012-02)
High country soils are typically acidic and have low fertility compared with intensive high fertility low land systems. Pasture legumes commonly used in New Zealand perform poorly in these environments. The optimum soil P ...
Potential pasture nitrogen concentrations and uptake from autumn or spring applied cow urine and DCD under field conditions
(MDPI, 2016-06)
Nitrogen (N) cycling and losses in grazed grassland are strongly driven by urine N deposition by grazing ruminants. The objective of this study was to quantify pasture N concentrations, yield and N uptake following autumn ...
Urine patch area coverage of an intensively stocked dairy pasture
(International Union of Soil Science, 2010-08)
The urine patch of the grazing cow has been identified as the key source of N loss from pasture-based dairy
systems. Although critical to N modelling, quantitative data on the annual area coverage of urine patches in
pastures ...
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.
Grazing and soil fertility effect on naturalized annual clover species in New Zealand high country
(Elsevier on behalf of the Society for Range Management, 2016-11)
With a view to increasing rangeland pasture legume abundance, the herbage biomass and seedling recruitment of four New Zealand naturalized annual clover species (haresfoot clover Trifolium arvense L., suckling clover T. ...
Potential profit gains from improving pasture productivity on New Zealand South Island high-country farms
(New Zealand Grassland Association, 2020-09-09)
Soil acidity combined with low levels of key nutrients on New Zealand hill-country farms are limiting factors for legume establishment/growth. However, legumes are a critical component of these farms as they provide nitrogen ...
Lucerne dry matter and N-fixation, when sown with or without lime and inoculant
(New Zealand Grassland Association, 2015-11)
This paper quantifies the effect of inoculation and lime on lucerne growth and nitrogen fixation over the establishment and following season. The field experiment at Ashley Dene, in Canterbury, had an initial soil pH of ...
Dry matter and sheep production of four dryland tall fescue-clover pastures 4-6 years after establishment
(New Zealand Grassland Association Inc., 2015)
Effects of tall fescue cultivar (‘Advance’ and ‘Flecha’) and clover species (white and subterranean (sub) clovers) combinations on pasture dry matter (DM) and sheep production were assessed in years four (2011/12), five ...
