Summary

This paper investigates the relationship between soil organic matter and the long-term availability of phosphorus, employing a biological phosphorus mining experimental framework. The research, as suggested by the title and journal scope, explores mechanisms by which organic matter may enhance or sustain phosphorus supply to plants. The findings contribute to understanding nutrient cycling in agricultural soils, with potential implications for reducing inorganic phosphorus fertiliser dependence.

UK applicability

Given the UK's established research groups in soil phosphorus management and the relevance of P sustainability across British agricultural systems, these findings are likely applicable to UK farming practice and policy discussions around phosphorus stewardship and circular nutrient cycling.

Key measures

Soil phosphorus availability over time; soil organic matter content; phosphorus extractability; biological P mining efficiency

Outcomes reported

The study evaluated how soil organic matter affects the long-term availability of phosphorus in soil using a biological phosphorus mining experimental approach. It measured phosphorus release and availability dynamics under controlled conditions.
