Medium-term soil pH and exchangeable aluminium response to liming at three high country locations
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 ...
Diverse bacterial taxa inhabit root nodules of lucerne (Medicago sativa L.) in New Zealand pastoral soils
Background and aims: Pseudomonas spp. have previously been isolated from lucerne nodules. The aims of this study were to: 1) investigate the microbiome within a lucerne nodule; and 2) assess the ability of two Pseudomonas ...
Multi-purpose rhizobia for nitrogen and phosphate mobilisation in pastures
Presentation made at 17th Australian Nitrogen Fixation Conference
Dry matter yield, root traits, and nodule occupancy of lucerne and Caucasian clover when grown in acidic soil with high aluminium concentrations
(Springer Verlag on behalf of the Royal Netherlands Society of Agricultural Science, 2017-07)
Aims and methods: Lucerne and Caucasian clover dry matter were measured in response to recommended lime and capital P inputs for six years in an acidic soil in the New Zealand high country. The initial three years of the ...
The mechanisms driving potato crop yield and grade distribution
Under ideal growing conditions (e. g. optimal moisture, temperature, mineral nutrition and disease control) potato dry matter (DM) yield increases with the amount of intercepted photosynthetic active radiation (PARi). ...
Yield, final population and emergence of seed treated lucerne (Medicago sativa L.) sown on five dates
(Australian Grasslands Association, 2012)
Dryland seedling lucerne establishment was examined at Lincoln University, Canterbury, New Zealand. Stands were sown on 4 October, 4 November, 2 December 201 O and 10 January and 7 February 2011 with four seed treatments; ...
Agricultural land rehabilitation following 2010 Darfield (Canterbury) earthquake: A preliminary report
(New Zealand Society for Earthquake Engineering Inc., 2010-12)
This paper describes the nature of earthquake damage and rehabilitation of rural land affected by fault rupture and liquefaction following the 4 September 2010 Darfield (Canterbury) Earthquake. Remediation of land damaged ...
Lamb liveweight gain on kura clover-ryegrass and white clover-ryegrass swards at two levels of soil fertility
Temporal and spatial variation in the performance of white clover (Trifolium repens L.) is viewed as potential limitation to reliance on this legume in temperate grasslands. One alternative is kura clover (Trifolium ambiguum ...
Coumestrol content of lucerne under drought stress
The response of coumestrol to water stress was assessed in two lucerne cultivars 'Wairau' and 'Kaituna'. Coumestrol content of lucerne is of importance because of its ingestion by ewes prior to and during the mating period ...
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
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 ...
