Resumo
The objective of this study was to evaluate the effects of
soil tillage and crop rotation systems on soil physical attributes.
The experiment was conducted for five consecutive years and
ten crop seasons in a dystrophic Oxisol in Santo Antônio de
Goiás, Goiás State, Brazil, in a completely randomized design
with four replications arranged in a 2 x 4 factorial split plot.
Tillage systems were assigned to plots: (P1) no-tillage followed
by plowing and (P2) continuous no-tillage; and crop rotations
were assigned to subplots: (R1) millet - common bean - millet -
common bean - rice - common bean - millet - common bean -
millet - common bean, (R2) millet - common bean - soybean -
common bean - rice - common bean - millet - common bean - corn
- common bean, (R3) millet - common bean - millet - common
bean - rice - common bean - corn - common bean, and (R4)
soybean - common bean - corn - common bean - rice - common
bean - soybean - common bean - corn - common bean. Tillage and
crop rotation systems affected soil bulk density, macroporosity,
and total porosity. Continuous no-tillage increased soil bulk
density and decreased soil macroporosity and total porosity.
Soil organic matter content was inversely correlated to soil bulk
density and directly correlated to soil macroporosity.
