Phosphorus
Adding phosphorus to soil can help grow plants – but too much in our water contributes to algal blooms. These resources can improve your understanding of how phosphorus moves from land to water, and help you find effective ways to minimise phosphorus loss.

Sediment and water-column phosphorus chemistry in streams at baseflow across varying catchment geologies
Streams can attenuate inputs of phosphorus (P) and therefore dampen the likelihood of ecosystem eutrophication. This P attenuation derives from many processes and remains poorly…

Minimizing phosphorus leaching from a sandy clay loam caused by phosphorus fertilizers
At moderate to high fertilization rates, sandy-textured soils can leach much phosphorus (P) threatening surface water quality. High rates are used to compensate for P…

The longevity of fencing out livestock as a method of decreasing contaminant concentrations in a headwater stream
Water quality can be improved by fencing off streams from livestock. However, the remedial effect of fencing can fail as livestock trample near stream areas.…

Dispersed forage feeding to minimise negative impacts on soil and water quality
Scott Hassall harvests kale at scale on his farm in North Canterbury. Harvesting kale, (mowing, chopping, and feeding out) is not common practice in New…

Actions to Include in a Farm Environment Plan
This interactive infographic is a compilation of actions to decrease the loss of contaminants from agricultural land. Mitigation actions can be filtered by any of…

Limiting grazing periods combined with proper housing can reduce nutrient losses from dairy systems
Pasture-based and grass-fed branding are often associated with consumer perceptions of improved human health, environmental performance and animal welfare. Here, to examine the impacts of…

Factors controlling shallow subsurface dissolved reactive phosphorus concentration and loss kinetics from poorly drained saturated grassland soils
Shallow subsurface pathways dominate dissolved reactive phosphorus (DRP) losses in grassland soils that are: poorly drained, shallow, or have a perched water table in wetter…
Summary
Nutrient losses from global dairy production systems differ
The demand for dairy produce is growing alongside concerns about the impact of intensive dairying on water quality owing to nutrient loss. We found that…

Phosphorus and iron-oxide transport from a hydrologically isolated grassland hillslope
Losses of N, P and Fe in drainage responded differently to waterlogging. Moderate nitrate concentration prevented Fe–P dissolution and loss in drainage. Low nitrate concentrations…

The longevity of cultivation in decreasing the potential for phosphorus loss in runoff
Phosphorus (P) loss from highly fertilised grazed pastures can impair surface water quality. High P concentrations in grazed pastures are maintained to boost legume production,…

A Global Database of Soil Plant Available Phosphorus
Soil phosphorus drives food production that is needed to feed a growing global population. However, knowledge of plant available phosphorus stocks at a global scale…
