The efficacy of liming in remediating acid soils in northern China is unclear. The impact of limestone application on cadmium accumulation in wheat and maize grains is not well understood. The study aims to fill this knowledge gap by investigating the use of limestone for controlling cadmium accumulation in these crops.
