A novel method to rapidly assess the suitability of water treatment residual and crusted concrete for the mitigation of point and nonpoint source nutrient pollution
(Elsevier, 2019-07-02)
Freshwater ecosystems worldwide are at risk of becoming degraded as a result of excessive inputs of phosphorus (P) associated with terrestrial activities. This study describes a novel methodology to rapidly assess the ...
An integrated assessment of nitrogen source, transformation and fate within an intensive dairy system to inform management change.
(Public Library of Science, 2019-07-23)
From an environmental perspective optimised dairy systems, which follow current regulations, still have low nitrogen (N) use efficiency, high N surplus (kg N ha-1) and enable ad-hoc delivery of direct and indirect reactive ...
Future phosphorus: advancing new '2D' allotropes and growing a sustainable bio economy
(Crop Science Society of America with American Society of Agronomy and Soil Science Society of America, 2019-07-11)
With more than 40 countries currently proposing to boost their national bioeconomies, there is no better time for a clarion call for a new bioeconomy, which, at its core, tackles the current disparities and inequalities ...
Mitigation of ammonia and greenhouse gas emissions from stored cattle slurry using acidifiers and chemical amendments
(Elsevier, 2019-07-28)
Cattle and cow slurry storage is a significant source of agricultural greenhouse gas (GHG) and ammonia (NH3) emissions. While acidification has been demonstrated to significantly reduce these emissions, a knowledge gap ...
Split phosphorus fertiliser applications as a strategy to reduce incidental phosphorus losses in surface runoff
(Elsevier, 2019-04-24)
Organic soils have low sorption capacities for phosphorus (P), and may pose a risk of P loss to water if P applications to these soils coincide with runoff events. Little is known about the magnitude of exports of P in ...
The use of rapid, small-scale column tests to determine the efficiency of bauxite residue as a low-cost adsorbent in the removal of dissolved reactive phosphorus from agricultural waters
(Elsevier, 2019-04-19)
Bauxite residue, the by-product produced in the alumina industry, is a potential low-cost adsorbent in the removal of phosphorus (P) from aqueous solution, due to its high composition of residual iron oxides such as hematite. ...
Developing and validating a decision support tool for media selection to mitigate drainage waters
(Elsevier, 2019-07-26)
The nitrate nitrogen (NO3-N) and ammonium (NH4-N) and/or dissolved reactive phosphorus (DRP) load in drainage water from farms can be managed by reactive or biological media filters. The nutrient content of the drainage ...
Pyrolysed waste materials show potential for remediation of trichloroethylene-contaminated water.
(Elsevier, 2019-12-17)
Trichloroethylene (TCE) is an Environmental Protection Agency priority pollutant associated with cancer in humans. With numerous industrial applications and regular landfill disposal, TCE is a common landfill leachate ...
Impact of P inputs on source-sink P dynamics of sediment along an agricultural ditch network
(Elsevier, 2019-12-19)
Phosphorus (P) loss from intensive dairy farms is a pressure on water quality in agricultural catchments. At farm scale, P sources can enter in-field drains and open ditches, resulting in transfer along ditch networks and ...
