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, ...
Changes in soil phosphorus availability and potential phosphorus loss following cessation of phosphorus fertiliser inputs
(CSIRO Publishing, 2013-09-23)
Long-term application of phosphorus (P) fertilisers to agricultural soils can lead to in the accumulation of P in soil. Determining the rate of decline in soil P following the cessation of P fertiliser inputs is critical ...
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 ...
Biochar adsorbed ammonia is bioavailable
(Springer Netherlands, under the auspices of the Royal Netherlands Society of Agricultural Science, 2012-01)
Biochar is produced as a by-product of the low temperature pyrolysis of biomass during bioenergy extraction and its incorporation into soil is of global interest as a potential carbon sequestration tool. Biochar influences ...
Biochar and fertiliser applications influence phosphorus fractionation and wheat yield
(Springer Berlin Heidelberg, 2014-01)
The use of biochar in agriculture to achieve the dual benefits of improving soil quality whilst sequestering carbon (C) has received much attention. However, in low-intensity broadacre agricultural systems where yield is ...
Metal bioavailability dynamics during a two-year trial using ryegrass (Lolium perenne L.) grown in soils treated with biosolids and metal salts
(CSIRO Publishing, 2012)
A 24-month field lysimeter experiment using ryegrass (Lolium perenne L.) grown in three soil types was used to investigate metal bioavailability dynamics following amendment with biosolids and metal salts (Cd, Cu, Ni, Zn). ...
Gradient differences in soil metal solubility and uptake by shoots and roots of wheat (T. aestivum)
(Springer Berlin Heidelberg, 2014-05)
The aim of this research was to identify and quantify gaps in currents methods and models for predicting the plant availability of selected nutrient and contaminant metals (Cu, Ni, Zn, Cd) in soil. This study investigated ...
Fate of phosphorus applied to soil in pig slurry under cropping in southern Brazil
(Elsevier, 2018-07-01)
Strongly weathered soils (such as Oxisols), are inherently phosphorus (P) limiting and highly P-sorptive thus requiring continued P inputs for productive agriculture. Constant P inputs result in accumulation of soil P with ...
Analysis of soil eDNA functional genes: Potential to increase profitability and sustainability of pastoral agriculture
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2016-10-01)
Management of soil biological resources to optimise plant production, efficiency of nutrient inputs, and system sustainability is an emerging opportunity for pastoral agriculture. To achieve these goals, suitable tools ...
Predicting the changes in environmentally and agronomically significant phosphorus forms following the cessation of phosphorus fertilizer applications to grassland
(Wiley on behalf of the British Society of Soil Science, 2012-06)
Phosphorus (P) loss from soil can impair surface water quality. Losses from soil are related to soil P concentrations, but agronomic measures such as Olsen P do not in many cases predict the potential for P loss. One ...
