Yield responses of arable crops to liming – An evaluation of relationships between yields and soil pH from a long-term liming experiment

Summary

This long-term field experiment quantifies yield responses of arable crops to soil liming and establishes critical soil pH values for economically optimal production. The work demonstrates that phosphate fertiliser application significantly lowers the critical pH threshold at which yield benefits from liming are realised, suggesting interactive effects between pH management and nutrient supply in arable systems.

UK applicability

Given the authors' affiliation with UK research institutions and the long-term nature of the trial, findings are directly relevant to United Kingdom arable practice and soil management policy. Results inform lime application decisions under British soil and climate conditions.

Key measures

Crop yields (unspecified crops), soil pH, critical pH values for yield response, interaction with phosphate fertiliser application

Outcomes reported

The study evaluated relationships between soil pH, liming treatments, and yield responses across multiple arable crops using long-term field trial data. Critical pH values were calculated for selected crops, and the modifying effect of phosphate fertiliser on these pH thresholds was quantified.
