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. ...
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 ...
Flooding-induced N₂O emission bursts controlled by pH and nitrate in agricultural soils
(Elseiver, 2014-02)
Agricultural soils are a major source of the greenhouse gas nitrous oxide (N₂O) to the atmosphere. Increasing frequency and severity of flooding as predicted for large intensively cropped areas may promote temporary ...
The effect of urinary nitrogen loading rate and a nitrification inhibitor on nitrous oxide emissions from a temperate grassland soil
(Cambridge University Press, 2014-12)
Nitrous oxide (N₂O) emissions associated with urine nitrogen (N) deposition during grazing are a major component of greenhouse gas emissions from domestic livestock. The present study investigated the relationship between ...
Advances in understanding nitrogen flows and transformations: Gaps and research pathways
(Cambridge Journals, 2014)
The nitrogen (N) cycle is one of the best studied elemental cycles. However, the N flows and transformations, in particular in aggregated soils, at small scales and in plant-soil systems are not yet fully understood. ...
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 ...
Fate of urine nitrogen through a volcanic vadose zone
(CSIRO, 2014)
© CSIRO 2014. To investigate the fate of nitrogen (N) from urine, dairy cow urine was amended with bromide (Br) and chloride (Cl), and applied onto a loamy sand soil with an underlying vadose zone of gritty coarse sands ...
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 ...
Soil profile inversion in earthquake-induced liquefaction-affected soils and the potential effects on urban trees
(Elsevier B.V., 2014-01)
A sequence of three large earthquakes in 2012/2011 caused liquefaction ground damage to over a third of Christchurch, New Zealand. This paper presents results of a characterisation of liquefaction-affected soil (LAS) and, ...
