The role of wetland restoration in mediating phosphorus ecosystem services in agricultural landscapes

Phosphorus (P) is an essential plant nutrient that often limits use, have significantly altered the P cycle, causing eutrophication of aquatic systems. Restoring wetlands to agricultural landscapes can retain P, improving water quality and other ecosystem services. The effectiveness of P retention in restored wetlands varies with hydrology, soil properties, vegetation, and other factors. Challenges such as wetland P saturation, legacy P release, and plant invasions can limit P retention capacity. Furthermore, climate-related changes in temperature and hydrology have the potential to undermine long-term P retention. New methods such as Integrated Constructed Wetlands and new technologies that provide highresolution temporal and spatial data enable managers to optimise multifunctionality in agricultural landscapes.
