“…The attribute elongation showed values below 1.0, inferring that the aggregates have a more polyhedral shape, confirming results obtained by Melo et al (2008). According to these authors, the elongation can occurs depending on the mineralogical composition, mainly in Oxisols, by the presence of kaolinite.…”

“…It was found that in the no-tillage system, there was decrease of the perimeter of aggregates with the increase of the depth. Melo et al (2008) discuss that this effect can be attributed to the composition of Oxisols, in which the larger amounts of gibbsite, goethite and hematite favoured the increase in the aggregate area, because of the greater tendency to neutralization of the negative charges on kaolinite particles, contributing for the growth of the aggregates. Means followed by the same small letter in the row and capital letter in the column are not significantly different by the test of Tukey (P <0.05).…”

“…Inadequate management and intensive soil utilization promote degradation of soil physical properties, mainly due to modifications of its original structure, which impairs the formation of stable aggregates in the soil (Melo et al, 2008), thus limiting crop productivity. The intensity with which these modifications occur depends on soil class, soil use and management systems employed (Centurion et al, 2001), which when are inadequate may reduce crop productivity (Lourente et al, 2011).…”

“…Na literatura científica, as formas de avaliação dos Agg centram-se principalmente em medidas de sua estabilidade e distribuição de classes por tamanho [3], de sua morfologia [4] e de sua resistência tênsil [5]. Contudo, poucos são os estudos que fazem menção a medidas da densidade de Agg (D Agg ), uma importante propriedade física de relação massavolume que está diretamente vinculada a estrutura do solo [6].…”
