Fig. 8. Concentration distributions of the tracers vs. depth. The total tracer concentration per volume of soil, 
t, was horizontally averaged and normalized by the total mass of tracer recovered per unit area, m0. Concentration distributions for sampling directly after application are shown for (a) Br– and (b) Brilliant Blue (BB), as well as for sampling after 90 d for (c) Br– and (d) Brilliant Blue. The data for Brilliant Blue represent averaged concentrations of 15 sampling locations corresponding to those where Br– was sampled (local scale).
