Therefore there's the necessity to add more knowledge about the mechanisms old degradation, transformation and reorganization of morph –structural analysis models associated with physical, biological and chemical relations when referring to horizontal and vertical zones the soil profile. Special attention was given to the of no tillage system planting adopting the culture sequences in succession an rotation, like the soil management in a continuous system and with mechanical interference. This study was carried out from 1998 to 2004 in the agronomy experimental area the Brazilian Agricultural Research Enterprise (EMBRAPA-CNPSo), Londrina (Paraná State), in Red Latosol (Rhodic Haplustox). The studied were no tillage system planting that has been continuous for 15 years and with mechanical interference, aiming at the rupture of superficial layer of soil every three years, cultivated with wheat/soybean succession and crop rotation systems, including soybean and/or maize in the summer, and wheat, black oat and/or white lupine, in the winter; areas under natural vegetation as reference for modifications. In this study they used the methodologies is morph-structural analysis and profile cultural, physical and chemical analyses. The study made in the area of roots, soil resistant to penetration, climate data organic residue in the soil studied areas during five years. The studies describer more perceptive modifications in the first 0,40 m of profundity with more horizontal variability of structural units between 0,5 and 0,20-0,25 m of profundity. With decrease of compression of soil surface into subsurface which developed itself localizing in horizontal space and only intra-aggregated. It has become evident that the availability and retention of water and nutrients in soil, the development of roots is a consequence of distribution, continuity and diameter of empty, type, class and localization of structure, and less dependent of value of soil density. It isn't evident the development of process of soil degradation as a productive way, as well a it's not described difference in productivity and due to systems of management and valued cultivation, the adaptation of rotation of cultures demonstrates essential to the continuity system, specially in the beginning.
