Fertilizer and stocking rates on two King Country soils
(New Zealand Grassland Association., 1973)
Parent materials such as volcanic ash and sedimentary siltstone
and sandstone form soils which differ markedly in their physical
and chemical properties. In stocking x fertilizer rate trials on
two families of soils, ...
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, ...
A synergistic mitigation technology for nitrate leaching and nitrous oxide emissions for pastoral agriculture
Report on a mitigation technology which is synergistic for the reduction of both NO3 leaching and N2O emissions and also for the improvement of pasture yield.
Inhibition of ammonia oxidisers to control nitrification rate under simulated winter dairy forage grazing conditions: An incubation study
(Fertilizer and Lime Research Centre, 2013)
The microbial process of nitrification plays a key role within the soil nitrogen cycle. Nitrification is the process where ammonia is oxidised to nitrite and then to nitrate and this process can have major negative ...
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 ...
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 ...
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 ...
