<abstract xmlns="http://www.w3.org/1999/xhtml"> We performed field experiment with 10 g l−1 concentration of Brilliant Blue solutes in 100 l of water sprinkling on 1 × 1 m surface of the Dystric Cambisol. Consequently, four vertical profiles were exposed at experimental plot after 2 hours (CUT 2), 24 hours (CUT 24), 27 hours (CUT 27) and after 504 hours (CUT 504) in order to analyse spatiotemporal interactions among the BB solution (Na-salts), soil exchangeable complex and fine earth soil (%) samples extracted from both the high and low coloured zones located around the optically visualised macropore preferred flow (PF) zones. The concentration changes were quantifying via soil profiles not affected by BB (termed as REF) located in the close vicinity of experimental plot. Observed changes in pH (H2O), chemical composition of fineearth soil, as well as in concentration of Na+ in soil exchangeable complex to suggest, the BB dye solution didn’t represent an inert tracer, but compounds strongly involved in reaction with surrounding soils. Recorded chemical trends seems to be the result both the competitive processes between the Na+ of BB dye solution and composition of surrounding soil exchangeable complex, as well and the spatial-temporal controlled mechanism of dye solution transfer in soil.</abstract>
