Resumo: | Currently the bigger limitation of the agricultural production and the quality of the environment of the mechanized areas is the compaction. The objective of this work was to evaluate the shear strength and the preconsolidation of a Red yellow Acrisol soil of the northeast semiarid, under conventional and no-tillage management. The soil samples were subject to uniaxial compression test where static loads of 25, 50, 100, 200, 400 and 800 were applied during 30 minutes. The tests of direct shear were realized with applying loads of 50, 100 and 200 kPa. The results showed that the maximum deformation, independent of management system, occurred in the first minutes, of the application of the load. The shear stress increased as far as the normal tension was applied to the soil. The conventional management was more susceptible to pressures applied in the soil when compared to no-tillage system. |
