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 ...
Medium-term soil pH and exchangeable aluminium response to liming at three high country locations
(NZGA, 2014-12-01)
Acid soil conditions and associated aluminium (Al) toxicity pose a serious impediment to legume establishment, persistence and productivity in high country. However, data that report soil exchangeable Al concentrations in ...
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 ...
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 ...
Soil pH, exchangeable aluminium and lucerne yield responses to lime in a South Island high country soil
(New Zealand Grassland Association, 2010)
A 2-year field experiment was conducted on a high
country brown stony soil in the Lees Valley, North
Canterbury. Two forms of lime (‘AgLime’ and
‘Quicklime’) were applied at 4 rates (0, 2, 4 and 8 t/
ha) and plots sown ...
Soil pH, exchangeable aluminium and legume yield responses to deep-placed lime at Omarama Station
(New Zealand Grassland Association, 2018-11-17)
The passive moment of lime down the soil profile in dryland is slow so a machine was developed to directly inject lime into soil, and was tested it at Omarama Station. Pelleted lime was injected at simultaneous depths of ...
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 ...
Caucasian clover responses to fertiliser, lime and rhizobia inoculation at Lake Heron Station, Canterbury
(New Zealand Grassland Association, 2014)
The agronomic performance of Caucasian clover in high country grasslands was the subject of two experiments at Lake Heron Station, Canterbury. In the first experiment, Caucasian clover was direct drilled into an undeveloped ...
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 ...
Lucerne (Medicago sativa L.) dry matter, root growth and nodulation in response to lime and phosphorus in an acid, high country soil in New Zealand
(2012)
Soil acidity is the main constraint for lucerne establishment and growth in high country regions of New Zealand. Root growth is suppressed in these aluminium-rich acid soils. In this experiment, lucerne was grown in PVC ...
