• Abstract:

  The objective of this work is to evaluate

  the soil physical attributes using two systems

  of soil tillage (conventional and no-tillage) in

  sugarcane renewable area. The study was carried

  out under field conditions at Usina Santa Fé, in

  Ibitinga-SP, with strips experimental design. Each

  experimental unit was repeated three times, the

  dimensions were 30 meters in length by 10 meters

  in width, amounting 300 m2.The used treatments

  were no-tillage using millet as crop rotation and

  conventional growing, which is used at the power

  stations. The no-tillage using millet has gotten

  better results for the analyzed attributes, such as

  less soil bulk density, bigger total porosity, having

  more macro and less microporosity on surface

  layers. The no-tillage has also had an average

  diameter on evaluated layers with values 50%

  greater than the conventional tillage, also a bigger

  aggregate stability index, proving that management

  more conservationist affects positively the soil

  structure.
