“…In the southern half of the state of Rio Grande do Sul (RS), Brazil, there are an estimated 5.4 million hectares of lowlands (Pinto et al, 2004), in which soils classified as Albaqualf predominate, occupying approximately three million hectares (Bamberg et al, 2009). These soils are characterized by the presence of a dense and practically waterproof B horizon (Santos et al, 2013) on which mostly rice is grown in the summer, and ryegrass pasture in the winter.…”

“…The predominant soil class in lowlands of Rio Grande do Sul is Albaqualf (Bamberg et al, 2009) formed inhydromorphic environment (Borges et al, 2004) with limited water drainage (Marchezan et al, 2002). When Albaqualf soils are cultivated with rainfed crops, as is the case of soybeans, plant growth and development may be hindered, mainly due to their naturally unfavorable physical conditions (Bamberg et al, 2009).…”

“…A maioria das áreas utilizadas para o cultivo do arroz irrigado pertence à classe Planossolos (Bamberg et al, 2009 leve, e contrastam abruptamente com o horizonte B, ou apresentam transição abrupta conjugada com acentuada diferença de textura do horizonte A para o B, são adensados, geralmente com elevada concentração de argila, e de permeabilidade lenta ou muito lenta. Em áreas de várzeas, em condições de clima úmido, são considerados hidromórficos, com horizonte plânico e apresentam características de horizonte glei (Santos et al, 2013).…”
