SUMMARY:

The study of changes in the physical and chemical attributes of the soil allows establishing parameters capable of assessing soil quality. The objective of this work was to test the hypothesis that the intensification of agriculture through the cultivation of sugarcane, corn and pasture alters physical and chemical properties of the soil, when compared to land use with native vegetation. Soil samples were collected in four areas (1 hectare each, with 12 sampling points) in three layers (0.0 – 0.10; 0.10 – 0.20; 0.20 – 0.30 m ) in the municipality of Anadia Lemon Tree (Alagoas State) and analyzed for acidity and CTC properties (pH, CTCpH7, base saturation, aluminum saturation, Al+H and Na), macronutrients (P, K, Ca and Mg) and attributes physical (soil texture, soil density, particle density, total porosity, soil mechanical resistance to penetration and aggregate stability). Data were analyzed using statistical programs.
