A review of the policies and implementation of practices to decrease water quality impairment by phosphorus in New Zealand, the UK, and the US
(Springer Netherlands, 2016-04)
© 2015, Springer Science+Business Media Dordrecht. The improper use of phosphorus (P) on agricultural land in developed countries is related to P losses that impair surface water quality. We outline policy in New Zealand, ...
A review of the cost-effectiveness and suitability of mitigation strategies to prevent Phosphorus loss from dairy farms in New Zealand and Australia
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc., 2012-05)
The loss of phosphorus (P) from land to water is detrimental to surface water quality in many parts of New Zealand and Australia. Farming, especially pasture-based dairying, can be a source of P loss, but preventing it ...
Relationship between sediment chemistry, equilibrium phosphorus concentrations, and phosphorus concentrations at baseflow in rivers of the New Zealand National River Water Quality Network
(American Society of Agronomy, Inc., 2015-05)
Stream sediments can act as a source or a sink of dissolved (filtered) phosphorus (P) via abiotic and biotic processes. The cumulative action and magnitude of abiotic processes has been quantified by the equilibrium P ...
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 ...
