Mass flow to the root surface is defined here as the concentration of an element in the bulk soil solution times the transpirational water uptake of the plant stand. The ratio of uptake of a mineral element to mass flow is called Mass Flow Coefficient (MFC). From an ecosystem study in a beech forestMFCs for 11 elements have been calculated from 3 years of(More)
