“…In agricultural soils, for example, crop performance tends to be maximized, and soil and environmental degradation tends to be minimized, when indicator parameters of soil physical quality are within their "ideal", "optimal" or "preferred" ranges" (e.g. Topp et al, 1997;Reynolds et al, 2002;Dexter, 2004a,b,c;Reynolds et al, 2007Mueller et al, 2008;Drewry et al, 2008).…”

“…A porosidade livre de água entre 0,10-0,15 m 3 m -3 é considerada capaz de promover adequadas trocas gasosas entre o solo e a atmosfera, sendo amplamente utilizada como referência para o satisfatório crescimento e desenvolvimento do sistema radicular das plantas (Grable & Siemer, 1968;Mueller et al, 2008;Reynolds et al, 2009). Em relação à Ds, o estabelecimento de um valor satisfatório, para ser utilizado como referência nos estudos que avaliam a qualidade física dos solos, não pode ser seguramente realizado, visto que esse atributo apresenta grande variabilidade em razão da classe textural e do teor de matéria orgânica dos solos (Dias Junior & Miranda, 2000).…”

“…Various authors have proposed minimum values of soil macroporosity as necessary for gas diffusion and for avoidance of physiological damage to plant roots, for example, ≥0.10 m 3 m -3 (Grable and Siemer, 1968) and ≥0.14 m 3 m -3 (Carter, 1988;Mueller et al, 2008;Reynolds et al, 2009). For most of the evaluated treatments, the macroporosity exceeded these minimum suggested values.…”
