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 ...
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 ...
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 ...
