Challenges and opportunities in harnessing soil disease suppressiveness for sustainable pasture production
Grasslands are an important source of biodiversity, providing a range of essential ecosystem services such as ensuring water quality and soil carbon storage. An increasing proportion of grasslands are used for pastoral ...
Effect of nitrogen and waterlogging on denitrifier gene abundance, community structure and activity in the rhizosphere of wheat
(Oxford University Press and Blackwell Publishing Ltd on behalf of the Federation of European Microbiological Societies, 2013-03-01)
Microbial denitrification plays a key role in determining the availability of soil nitrogen (N) to plants. However, factors influencing the structure and function of denitrifier communities in the rhizosphere remain unclear. ...
Complexity of clay mineral formation during 120,000 years of soil development along the Franz Josef chronosequence, New Zealand
(Taylor & Francis Group on behalf of the Royal Society of New Zealand, 2017)
Weathering of primary silicates to secondary clay minerals over time affects multiple soil functions such as the accumulation of organic matter and nutrient cations. However, the extent of clay mineral (trans)formation as ...
Influence of soil bulk density and matric potential on microbial dynamics, inorganic N transformations, N₂O and N₂ fluxes following urea deposition
(Elsevier Ltd., 2013-10)
Transformation of ruminant urine-nitrogen (N) can contribute to negative environmental outcomes such as nitrate leaching which leads to eutrophication of waterways and production of nitrous oxide (N₂O), a greenhouse gas. ...
Effect of soil moisture and bovine urine on microbial stress
(Elsevier on behalf of Urban and Fischer, 2012)
While many studies have examined the cycling of urinary nutrients, few have focused on the effects ruminant urine might have on the soil microbial community. Urine application can cause microbial communities to become ...
Soil organic phosphorus transformations along a coastal dune chronosequence under New Zealand temperate rain forest
The chemical composition of soil phosphorus can vary markedly during pedogenesis, which has implications for phosphorus availability to plant and microbial communities during long-term ecosystem development. We used NaOH–EDTA ...
Biogeochemistry and community ecology in a spring-fed urban river following a major earthquake
(Elsevier B.V., 2013-11)
In February 2011 a Mw 6.3 earthquake in Christchurch, New Zealand inundated urban waterways with sediment from liquefaction and triggered sewage spills. The impacts of, and recovery from, this natural disaster on the stream ...
Research and application of biochar in New Zealand
(ASA / CSSA / SSSA, 2016)
Readers will appreciate the comprehensive review of the latest biochar research and applications and gain critical guidance in best biochar generation and use.
Validating novel oligonucleotide primers targeting three classes of bacterial non-specific acid phosphatase genes in grassland soils
(Springer International Publishing, 2018-06)
Background and aims: Microbially driven mineralization of organic phosphorus forms is of particular importance in the soil environment, where it becomes available to plants as inorganic orthophosphates. In acidic soils, ...
Sixty years of seasonal irrigation affects carbon storage in soils beneath pasture grazed by sheep
(Elsevier BV, 2012-02-15)
For sixty years at Winchmore, South Island, New Zealand (43°48′S, 171°48′E, 160 masl), stoney soils under continuous pasture grazing by sheep have received rainfall (nil irrigation) or rainfall and irrigation as required ...
