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.

Why are median phosphorus concentrations improving in New Zealand streams and rivers?
Between 2004 and 2013 phosphorus concentrations decreased at 65% of the 304 sites monitored. Our research found the most probable causes of improvement were that…

The efficacy of good practice to prevent long-term leaching losses of phosphorus from an irrigated dairy farm
We measured P fractions in leachate at 70cm depth from two soils of low-P sorption capacity in an intensively grazed dairy farm. In response to…

Transforming phosphorus use on the island of Ireland: A model for a sustainable system
Phosphorus is an essential part of the world food web and a non-substitutable nutrient in all biological systems. A key global challenge is to meet…

A Global Perspective on Phosphorus Management Decision Support in Agriculture: Lessons Learned and Future Directions
The evolution of phosphorus (P) management decision support tools and systems has been most strongly affected in developed regions by national strategies (i) to optimize…

A global perspective on the history of phosphorus management decision support approaches in agriculture: Lessons learned and directions for the future
The evolution of phosphorus (P) management decision support tools (DSTs) and systems (DSS), in support of food and environmental security has been most strongly affected…

Direct exports of phosphorus from fertilizers applied to grazed pastures in Australasia
The 4R concept was developed to help mitigate P exports. This review investigates the factors affecting P exports soon after the application of mineral fertilizers…

The potential for potassium chloride fertiliser applications to leach cadmium from a grazed pasture soil
Cadmium (Cd) is a biotoxic element that can enter the human food chain via plants grown in Cd-enriched soil. Chloride (Cl) can solubilise Cd in…
Journal Article
The mitigation of phosphorus losses from a water repellent soil used for grazed dairy farming
Soil water repellency (SWR) decreases the infiltration rate of soil, increasing the potential for surface runoff in response to rainfall (Bauters et al., 2000). The…
Journal Article
The ability to reduce soil legacy phosphorus at a country scale
The build-up of soil phosphorus (P) beyond plant requirements can lead to a long-term legacy of P losses that could impair surface water quality. Using…
Journal Article
Global mapping of freshwater nutrient enrichment and periphyton growth potential
Periphyton (algal) growth in many freshwater systems is associated with severe eutrophication that can impair productive and recreational use of water by billions of people.…
Journal Article
Dynamics of phosphorus exchange between sediment and water in a gravel-bed river
Phosphorus (P) stores in gravel-bed rivers are released for uptake by periphyton when pH levels exceed 8.5. The Tukituki River has low alkalinity water and…
Journal Article
Changes in soil cadmium concentrations with time following cessation of phosphorus fertilizer inputs
Cadmium (Cd) can accumulate in soil from the application of phosphorus fertilizer. However, there is little information on what happens to soil Cd concentrations when…
