Nitrate removal efficiency and secondary effects of a woodchip bioreactor for the treatment of agricultural drainage
(Fertilizer and Lime Research Centre, 2019-02)
Artificial drainage has been instrumental in the viable use of poorly drained soils for agriculture. However, artificial drains can also provide a pathway for fast and unattenuated nutrient transfers to streams and rivers. ...
Global database of diffuse riverine nitrogen and phosphorus loads and yields
(Wiley on behalf of the Royal Meteorological Society, 2020-11-24)
Human activities have increased the input of nitrogen and phosphorus into riverine systems. These inputs can increase algal growth that degrades aquatic ecosystems. We constructed a global database of diffuse loads (kg) ...
The use of alum to decrease phosphorus loss from dairy farm laneways in southern New Zealand
(British Society of Soil Science, 2016-03)
© 2016 British Society of Soil Science. Dairy farm laneways are sources of enriched P loss. Aluminium sulphate (alum) has been shown to decrease P loss when applied to land; our hypothesis was that alum may serve as a ...
Using the provenance of sediment and bioavailable phosphorus to help mitigate water quality impact in an agricultural catchment
(American Society of Agronomy, Inc., 2016-07)
The quality and health of surface waters can be impaired by sediment and sediment-bound phosphorus (P). The Waituna Lagoon catchment in southern New Zealand has undergone agricultural intensification that has been linked ...
