dc.description.abstractThe cultivation of the soil causes changes in physical attributes, depending on the intensity of preparation and management. The objective of this work was to evaluate the degree of modification of some physical properties of soil and the S index, comparing areas of pasture of grass Tanzania (Panicum maximum) and native forest with an area under maize (Zea mays L.) irrigated bay, a central pivot. The study was conducted in three areas within the Agency of Technology Agribusiness Paulista (APTA) Regional High Mogiana, located in Colina, SP. The experimental design was split plot in a factorial 3 x 3, with 4 replications, where the plots were installed in areas of cultivation of corn, pasture and forest in the depths 0-0.1 m, 0.1-0.2 m 0.2-0.3 m. The physical attributes of soil were: resistance to penetration (RP), bulk density (Ds), microporosity (Micro), macroporosity (Macro), total volume of pores (VTP) and water retention in soil. The native forest had the best physical condition of soil in all parameters examined. The use of land and pasture with corn altered the physical structure of it, evidenced by the increase in penetration resistance and soil density and, reduction in macroporosity. The level of degradation of the managed soil was considered low, index S (<0035). The replacement of pasture by the corn crop in the soil tillage system provided a conventional mild improvement in soil physical characteristics.en
