Using organic phosphorus to sustain pasture productivity: A perspective
(Elsevier, 2014-06)
Organic phosphorus (P) in grazed pastures/grasslands could sustain production systems that historically relied on inorganic P fertiliser. Interactions between inorganic P, plants and soils have been studied extensively. ...
Co-occurring increased phosphatase activity and labile P depletion in the rhizosphere of Lupinus angustifolius assessed with a novel, combined 2D-imaging approach
(Elsevier, 2021-02)
Innovative non-destructive 2D imaging methods such as zymography and diffusive gradients in thin films (DGT) have been developed recently to assess the distribution of phosphatase activity and labile solutes at the root-soil ...
Phosphorus leaching from an organic and a mineral arable soil in a rainfall simulation study
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2018-05-03)
Phosphorus derived from agricultural systems has been found to cause eutrophication of surface waters. To combat this, the specific location of soil profile P release is necessary for development of effective mitigation ...
Effects of elevated nitrogen and precipitation on soil organic nitrogen fractions and nitrogen-mineralizing enzymes in semi-arid steppe and abandoned cropland
(Springer Verlag on behalf of the Royal Nethlands Society of Agricultural Science, 2017-04-12)
Aims: Soil organic nitrogen (N) turnover is significantly influenced by elevated N deposition, precipitation and human-caused disturbances, but the underlying mechanism remains unclear. Identifying the relationships among ...
Mobilisation of recalcitrant soil nutrient fractions supports foliar nitrogen to phosphorus homeostasis in a seabird soil
(Springer Verlag on behalf of the Royal Netherlands Society of Agricultural Science, 2014-12)
Although the nutrient enrichment literature emphasises anthropogenic sources, seabirds deposit large quantities of marine detritus at breeding and roosting sites. Little is known of the chemical fractions and plant ...
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, ...
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 ...
A wood based low-temperature biochar captures NH₃⁻N generated from ruminant urine-N, retaining its bioavailability
(Springer Netherlands on behalf of the Royal Netherlands Society of Agricultural Science, 2012-04)
Aims: Ammonia (NH₃) can be volatilised from the soil surface following the surface application of nitrogenous fertilisers or ruminant urine deposition. The volatilisation of NH₃ is of agronomic and environmental concern, ...
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 ...
