摘要: Inadequate handling leads to the degradation and decrease in yield of many crops. The objective this work was evaluate alterations resistance penetration density soil due systems tillage, during after intensive cultivation five years fallow a Red Eutrophic Latosol (Eutrudox). Two tillage (tillage with harrow plow reduced rotary tilling) three sampling times comprising agricultural 1992/1993, 1993/1994 (under intense cultivation) 1999/2000 (five under fallow) were studied. For evaluation at different samplings, used as parameters. affected significantly studied depths. In soil submitted long period, increased significantly, compared cultivation, independently system previously used. responsible for largest period.
