Soil acidity and aluminium in South Island high and hill-country: New data and future needs
(New Zealand Grassland Association, 2018-11-19)
Soil extractable aluminium (A1) concentrations can have a strong impact on the establishment, growth and persistence of pasture legumes. This has become clear in New Zealand high and hill-country, where legumes are scarce ...
A field survey of soil pH and extractable aluminium in the Ashburton Lakes Catchment, New Zealand
(New Zealand Grassland Association, 2018-11-13)
Soil extractable aluminium (Al) concentrations have a strong impact on the establishment, growth and persistence of pasture legumes. A survey of 21 soil profiles in the Ashburton Lakes catchment was conducted to ...
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 ...
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, ...
Soil aluminium toxicity in New Zealand pastoral farming — A review
(New Zealand Grassland Association, 2018-11-13)
As most New Zealand pastoral soils are acidic, aluminium (Al) can be present at high concentrations and restrict plant root growth and shoot yield. In field trials, Al toxicity in white clover has been associated with ...
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.
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 ...
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 ...
Effects of perennial (‘Russell’) lupins on soil nitrogen and carbon in acid high-country soils
(New Zealand Grassland Association, 2018-11-13)
Many high-country soils in the South Island have low soil pH and high exchangeable Al concentrations, limiting establishment and persistence of pasture and forage legumes. Perennial lupin (Lupinus polyphyllus) is able to ...
