“…showed lower TDS values respect to the top and middle ones, with an evident increase during the storm events implying fast solutes transport from the topsoil to the column outflow, with constant values towards the end of the SR experiment. This pattern has been recently recognized also in field experiments (Fishkis et al, 2020). TDS concentrations at the column's outflow were always close to the ones registered within the column, with spikes after the storm events that confirm the preferential flow in macropores, as denoted before.…”

“…The plow pan tended to retard the vertical movement of water and solute, and thereby to cause redistributions more or less. But unless too heterogeneous, such as cracked at some spots but impermeable at the others, it would not greatly modify the relative distribution patterns of water amount and flux in the horizontal direction inherited from the surface arrangements of rainfall amount and intensity (Fishkis et al., 2020; Janssen & Lennartz, 2007). Therefore, the signs of the corresponding spatial correlations between Br − and rainfall characteristics at and below the plow pan remained the same, although the strengths somewhat decreased (Figures 7p–r,u–w and 9p–r,u–w).…”

“…In the last 20 years, more than 200 papers have been published on ISI journals (Figure 1). The TL-ERT method found an impressive number of applications crossing different disciplines, from hydrogeology [9][10][11][12] to agriculture [13][14][15][16], from engineering geology [17][18][19][20] to geohazards [21][22][23][24], from CO2 storage [25] to the study of the effects of the climate changes on soil and near subsurface [26][27][28][29].…”
