Influence of soil pH, phosphorus and sulphur on the frequency of rhizobia genotypes found in four pasture legume species grown in an acid high country soil
(Lincoln University, 2014)
South Island hill and high country soils typically have deficiencies of nitrogen, phosphorus, sulphur and molybdenum. The soils often have low pH and as such, high levels of exchangeable aluminium and manganese, causing ...
Effects of lime, phosphorus and sulphur on the establishment of Hairy Canary and Tagasaste on an acid high country soil.
(Lincoln University, 2014)
Legumes play a critical role in New Zealand high country farming systems as the sole provider of nitrogen (N) to the pasture sward through biological nitrogen fixation. N also increases the quantity and quality of pastures ...
Intraspecific variation in indirect plant-soil feedbacks as a driver of a wetland plant invasion
(Cold Spring Harbor Laboratory, 2017-07-07)
Plant-soil feedbacks (PSFs) can influence plant competition via direct interactions with pathogens and mutualists or indirectly via apparent competition/mutualisms (i.e., spillover to co-occurring plants) and soil legacy ...
Invasive belowground mutualists of woody plants
(Springer International Publishing, 2014-03)
Most plants require mutualistic associations to survive, which can be an important limitation on their ability to become invasive. There are four strategies that permit plants to become invasive without being limited by a ...
Mānuka (Leptospermum scoparium) roots forage biosolids in low fertility soil
(Elsevier B.V., 2017-01)
Potentially, biosolids could be applied to low fertility or degraded soils to establish mānuka (Leptospermum scoparium), an economically important plant species used for honey and essential oil production. Given that this ...
Localized flux maxima of arsenic, lead, and iron around root apices in flooded lowland rice
(American Chemical Society, 2014-08-05)
In wetland-adapted plants, such as rice, it is typically root apexes, sites of rapid entry for water/nutrients, where radial oxygen losses (ROLs) are highest. Nutrient/toxic metal uptake therefore largely occurs through ...
Mechanisms of growth promotion by members of the rhizosphere fungal genus Trichoderma
(CAB International, 2017)
Trichoderma spp. are best known for their biocontrol capabilities against a range of phytopathogenic microorganisms and increased plant drought tolerance. However, all the attributes of Trichoderma are also related to ...
The rhizospheres of arid and semi-arid ecosystems are a source of microorganisms with growth-promoting potential
(CAB International, 2017)
Discussion of rhizospheres of arid and semi-arid ecosystems
Testing the co-invasion hypothesis: ectomycorrhizal fungal communities on Alnus glutinosa and Salix fragilis in New Zealand
(John Wiley & Sons, Inc, 2015-03)
It has been proposed that co-invasion with ectomycorrhizal (EM) fungi is a common mechanism by which non-indigenous trees overcome symbiont limitation, yet virtually all prior evidence has come from a single plant family, ...
Rumen function and foraging behaviour of non-lactating, pregnant dairy cows wintered on kale or grass
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2019)
An outdoor grazing study conducted with 45 non-lactating, pregnant dairy cows during winter measured dry matter (DM) intake, grazing behaviour, rumen pH, ammonia (NH₃) and volatile fatty acids (VFAs) of cows fed 11 (K11) ...
