The role of root interception, mass‐flow and diffusion in supplying ions to soybeans growing in a leached subsoil was investigated. Root interception was the main mechanism for the supply of Cu, Al and Sr to the soybean roots. Mass‐flow was the most important for B and diffusion was the most important for Mn, Fe and Zn. The most significant mechanisms will likely vary with the crop grown, climate and soil.
