“…This was also reported by Silva & Ribeiro (1997) Soil bulk density values for the BCH and MCH were the same, and significantly higher than soil bulk density under native forest. The increase in soil bulk density at a depth of 0.20 m is due to heavy machinery traffic during sugarcane planting and harvesting, mainly for the MCH system.…”

SUMMARYThis study had the purpose of evaluating the effects of two management types of sugarcane: harvesting of burnt cane (BCH) and mechanized harvesting of unburnt green cane (MCH), on some soil physical properties of a dystrophic Rhodic Haplustox. The data were then compared with results for the same soil type under native forest. A completely randomized design was used, with three treatments and 20 replications. The following characteristics were determined: organic matter, aggregate stability, soil bulk density, and porosity at depths of 0-0.20 m and soil penetration resistance. After 15 years of cultivation, there were some alterations in the soil under cane burnt before harvesting, evidenced by a drop in the weighted average diameter of stable aggregates in water and increased soil bulk density. Significant changes were also detected in total porosity and pore distribution under both harvesting systems. Critical values for penetration resistance were observed in the area under mechanized sugar cane harvesting, with a value of 4.5 MPa in the 40-55 cm layer. This value is considered high and could indicate compaction and restriction of root growth. Soil properties under the green cane (unburned) management system were closest to those of the soil under native forest.Index terms: Saccharum officinarum, soil bulk density, porosity, soil penetration resistance, soil aggregate stability.(

“…Observa-se, ainda no quadro 6, que o solo 6, com 780 g kg -1 de argila, apresentou o maior valor de Ks (61,9 cm h -1 ). Esses resultados corroboram as observações de Fernandes et al (1978), Resende (1985) e Silva & Ribeiro (1997).…”

“…Mesmo no Argissolo Amarelo distrófico típico (PAd3), perfil sob mata, os valores de Ds foram elevados, reiterando as constatações de diversos autores (Achá Panoso, 1976;Universidade Federal de Viçosa, 1984;Anjos, 1985;Fonseca, 1986;Silva & Ribeiro, 1997) de que a coesão é herdada geneticamente. O fato de a coesão não apresentar-se em todo o perfil do solo justifica-se pela presença da matéria orgânica nos horizontes superficiais e, talvez, pelo umedecimento mais pronunciado em profundidade.…”
