The Central Depression of the State of RS has mainly Haplic Planosol soil, which is hydromorphic due to a reduced infiltration capacity and high compaction rates (SARTORI et al.
The soil used was collected at the 0-20 cm depth and classified as moderate A Tb typic eutrophic Haplic Planosol, with sandy texture (EMBRAPA, 2006).
The vases were filled with sieved soil that was collected from the A1 horizon of a Haplic Eutrophic Planosol Solodi soil (EMBRAPA, 2006) in Pelotas.

The soils were classified by Brasil (1972) and fit in the new classification proposed by EMBRAPA (2006) as Yellow Argisol (PA); Gray Argisol (PAC); Eutrophic Red Argisol (PVe); Red Yellow Argisol (PVA); Yellow Latosol (LA); Distrophic Red Argisol (PVd); Regolithic Neosol (RR); Litholic Neosol (RL); Haplic Luvisol (TX); Haplic Planosol (SX); Fluvic Neosol (RY); and Haplic Vertisol (VX).
