“…Prior research has identified that soil conditions, such as macroporosity below 10% and penetration resistance above 2 MPa, which were found in the non-aerated soil, represent poor aeration, restrict the movement of water and nutrients, and inhibit growth of plant roots (Climo & Richardson 1984;Hamblin 1985;Asady & Smucker 1989;Bengough & Mullins 1991;Taylor & Brar 1991;Greenwood & McNamara 1992;Ley et al 1995;Cook et al 1996). Aeration reduced penetration resistance, degree of packing, and bulk density, and increased hydraulic conductivity, total porosity, macroporosity, and the proportion of smaller aggregates when compared with non-aerated soil.…”

“…Segundo Taylor & Brar (1991), os níveis críticos de resistência do solo para o crescimento das plantas variam com o tipo de solo e com a espécie cultivada. Em Latossolo Vermelho, Petter (1990) verificou que a resistência de 2,8 MPa foi limitante ao crescimento radicular da soja.…”

“…Um solo compactado tem o arranjo estrutural, a porosidade total, a difusão de gases, a infiltração e o armazenamento de água comprometidos, que, por conseqüência, afetam o crescimento radicular das plantas (Taylor & Brar, 1991). Por sua vez, o rompimento de camadas compactadas do solo por meio de equipamentos motomecanizados tem custo elevado (Dias Junior, 2000).…”
