Summary

This Nature Sustainability perspective by Withers examines approaches to closing the phosphorus cycle in agriculture, a critical challenge given finite rock phosphate reserves and environmental losses from farming. The paper likely synthesises evidence on phosphorus recovery from waste streams, improved fertiliser use efficiency, and policy mechanisms to support circular nutrient management. As suggested by the 2019 publication date and journal scope, it positions phosphorus stewardship as essential for long-term food security and environmental sustainability.

UK applicability

The findings are highly applicable to UK farming policy, particularly regarding nutrient management regulations under the Nitrates Directive and emerging circular economy agendas. UK livestock and horticulture sectors are major phosphorus consumers and generators of recoverable phosphorus in manures and food waste, making phosphorus cycle closure strategically relevant.

Key measures

Phosphorus cycle efficiency, nutrient recovery rates, recycling pathways in agricultural systems

Outcomes reported

The paper examines strategies and barriers to closing phosphorus cycles in agriculture, likely considering nutrient recovery, recycling pathways, and policy interventions. It assesses the current state of phosphorus management in food production systems.
