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 ...
Influence of environmental factors on the abundance of naturalised annual clovers in the South Island hill and high country
(New Zealand Grassland Association., 2010)
The abundance of four naturalised annual clovers
(striated, cluster, suckling, haresfoot) and two
sown clovers (subterranean and white clover) was
investigated in relation to topographical, soil fertility
and management ...
The fate of urine nitrogen: A grassland lysimeter study in Ireland
(Fertilizer and Lime Research Centre, 2014-02)
In grazed pasture systems, the nitrogen (N) contained in a cattle urine patch may be up to 1200 kg N ha⁻¹. The majority of this N is in excess of plant requirements and is vulnerable to environmental loss. In this study, ...
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 ...
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 ...
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. ...
Potassium dynamics of four grassland soils contrasting in soil K management history
(Wiley on behalf of the Japanese Society of Grassland Science, 2013-03)
Potassium (K) management is important in grassland systems, especially in dairy farming. The interactions of K with other nutrients, such as magnesium (Mg), and enhanced K levels themselves can have impacts on metabolic ...
Factors influencing fertiliser and lime decisions on South Island high- and hill-country farms
(New Zealand Grassland Association, 2020-09-09)
Highlights • Fertiliser and lime decisions by high-and hill-country farmers directly impact on their farm performance, but the factors influencing these decisions are not well understood. • Factors influencing South Island ...
Lime, phosphorus and sulphur response of French serradella (Ornithopus sativus) grown in an acid upland soil
(International Scientific Publications, 2014-06-01)
Soil acidity severely restricts legume persistence and growth in grazed upland agriculture in New Zealand. An alternative and potentially acid tolerant forage legume, French serradella (Ornithopus sativus), was examined ...
Confirmation of co-denitrification in grazed grassland
(Nature Publishing Group, 2015-11-30)
Pasture-based livestock systems are often associated with losses of reactive forms of nitrogen (N) to the environment. Research has focused on losses to air and water due to the health, economic and environmental impacts ...
