The present work aimed to characterize the chemical, physical and organic matter attributes on three land use systems (No Tillage System-NTS, Livestock Forestry Integration-LFI and Native Forest-NF), adopted in an agricultural property. Soil deformed samples were collected for texture and chemical analysis. For density, particle density and soil density analysis, undisturbed samples were collected at different depths. As for texture, the NTS was characterized as clayey and the LFI and NF systems as sandy. For the Particle Density (Pd), the systems did not differ statistically at the depth of 0-5 cm, and the other depths differed significantly only between NTS and NF. As for the Soil Density Sd, the LFI and NF systems did not differ from each other and showed the highest value. In macroporosity, at depths of 0-5 cm and 5-10 cm, there was a significant difference only between NF and LFI systems. In NTS the microporosity, the levels of Ca, Mg, P and K and O.M (0-10cm) were higher. For the O.M the NTS and NF presented similar values. The evaluated characteristics were influenced by the soil texture and not by the adopted system. The producer makes use of that information to implement the appropriate system.
