Soil biodiversity and biogeochemical function in managed ecosystems
(CSIRO, 2020-01)
A complex combination of environmental, biological, chemical, and physical properties and processes determine soil biodiversity and its relationship to biogeochemical functions and ecosystem services. Vegetation, land-use, ...
A bioassay to compare the disease suppressive capacity of pasture soils
(New Zealand Plant Protection Society (Inc.), 2015)
© 2015 New Zealand Plant Protection Society (Inc.). Dynamic pathogen complexes can develop under pastures, thereby substantially reducing potential productivity. Suppression of such pathogen complexes is therefore of great ...
Protecting the unseen majority: Land cover and environmental factors linked with soil bacterial communities and functions in New Zealand
(New Zealand Ecological Society, 2021)
The biodiversity in soil ecosystems is simultaneously incredibly rich and poorly described. In countries such as New Zealand, where high endemism in plant species emerged following extended geographical isolation, it is ...
Effects of long-term irrigation on soil phosphorus under temperate grazed pasture
(Wiley on behalf of British Society of Soil Science, 2018-01-18)
The effect of 62 years of different irrigation regimes on the amounts, forms and distribution of phosphorus (P) in the soil profile to 100 cm under grazed pasture was determined. Irrigation treatments included nil irrigation ...
Biotic interactions drive ecosystem responses to exotic plant invaders
(American Association for the Advancement of Science, 2020-05-29)
Ecosystem process rates typically increase after plant invasion, but the extent to which this is driven by (i) changes in productivity, (ii) exotic species' traits, or (iii) novel (non-coevolved) biotic interactions has ...
Effect of land use and soil organic matter quality on the structure and function of microbial communities in pastoral soils: Implications for disease suppression
(Public Library of Science, 2018-05-07)
Cropping soils vary in extent of natural suppression of soil-borne plant diseases. However, it is unknown whether similar variation occurs across pastoral agricultural systems. We examined soil microbial community properties ...
Impact of grassland afforestation with contrasting tree species on soil phosphorus fractions and alkaline phosphatase gene communities
(Elsevier BV, 2021-08)
While grassland afforestation can enhance the net mineralization of soil organic phosphorus (P), the mechanisms involved and impacts of different tree species are not clear. Soil samples were taken from replicated adjacent ...
Challenges and opportunities in harnessing soil disease suppressiveness for sustainable pasture production
(Elsevier, 2016-04)
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 ...
Long-term irrigation effects on soil organic matter under temperate grazed pasture
(John Wiley & Sons, Inc. on behalf of the British Society of Soil Science, 2014-09)
© 2014 British Society of Soil Science. Irrigation of grazed pasture significantly increases plant and animal production, which may in turn increase soil organic carbon (SOC), depending on the balance between primary ...
Mechanisms of pollution induced community tolerance in a soil microbial community exposed to Cu
(Elsevier B.V., 2014-07)
Pollution induced community tolerance (PICT) to Cu²⁺, and co-tolerance to nanoparticulate Cu, ionic silver (Ag⁺), and vancomycin were measured in field soils treated with Cu²⁺ 15 years previously. EC₅₀ values were determined ...
