Dynamics of soil phosphorus measured by ammonium lactate extraction as a function of the soil phosphorus balance and soil properties

Summary

This study, as suggested by the title and journal scope, investigates the relationship between soil phosphorus dynamics measured via ammonium lactate extraction and the cumulative phosphorus balance of soils, accounting for soil-specific properties. The work appears to assess how well this extraction method reflects actual soil phosphorus availability across varying pedological conditions. Findings have implications for interpreting soil phosphorus test results in agronomic advisory systems.

UK applicability

The ammonium lactate extraction method is used in UK soil testing laboratories for phosphorus availability assessment; findings on how this method performs across different soil types and phosphorus balance states would be directly relevant to UK fertiliser recommendation systems and soil health monitoring practices.

Key measures

Ammonium lactate-extractable soil phosphorus; soil phosphorus balance; soil chemical and physical properties including pH, texture, organic matter content

Outcomes reported

The study examined how ammonium lactate extraction measures soil phosphorus availability as a function of cumulative phosphorus balance (inputs minus outputs) and various soil properties. The research quantified relationships between extractable phosphorus and soil characteristics across multiple sites.
