The soil material used came from the A horizon of a Planosol
The second experiment with the same irrigated rice cultivars was performed in vessels with a capacity of 9L containing 7kg of a typical hydromorphic haplic planosol
soil (EMBRAPA, 2013).
The experimental units were composed of a potted barnyardgrass plant, with a volumetric capacity of 4L, containing dystrophic Haplosol planosol
. The soil analysis showed: pH in water = 5.0; [CTC.sub.pH7] = 7.2 [cmol.sub.c] [dm.sup.-3]; organic matter = 1.5%; clay = 16%; texture = 4; Ca = 4.1 [cmol.sub.c] [dm.sup.-3]; Mg =1.1 [cmol.sub.c] [dm.sup.-3]; Al = 1.8 [cmol.sub.c] [dm.sup.-3]; P = 6.5 mg [dm.sup.-3] and K = 0.15 [cmol.sub.c] [dm.sup.-3].
There is also, in small proportions, Eutric Cambisol--cx (Cambisol), Eutric Fluvisol--ru (Alluvial soil), Haplic planosol
sco) and rocky outcrops with evidence of Lithic entisol (CHAVES et al., 2002).

There are 27 soil types, among them are different classes of cambisols, fluvisols, and solonchaks, as well as eutric planosol
, calcareous phaeozem, calcareous vertisol, calcareous regosol and humic gleisol (INEGI 2012).
