GARCIA RUIZ, Inoel et al. Effect of the compaction on the physical properties of the soil and the growth of the sugarcane. Rev Cie Téc Agr [online]. 2010, vol.19, n.2, pp.51-56. ISSN 2071-0054.

The compaction of the soil in experimental plots of cane of sugar increased the bulk density from 1,3 to 1,4 g•cm-3, the resistance of 2665,2 to 4515,2 kPa and it diminished the porosity from 51,9 to 48,2%. At 11 months the compacted non-cultivated soil treatment (CNC) bulk density was reduced in 5,7%, the resistance in 31,4% and the total porosity increased in 2,3%, attributable to the capacity resilient of the soil. The treatment compacted-cultivated (CC) diminished the bulk density in 7,9%, the resistance in 47,6% and the total porosity increased in 3,5%. The amplitude of the optimum water interval (OWI) was reduced at CNC compared with CC treatment, with a critical bulk density of 1,28 g•cm-3 y 1,36 g•cm-3, respectively.

Palavras-chave : soil resistance; bulk density; porosity; optimum water interval.
