| Abstract | The aim of this study was to accomplish an exploratory study of the stillage in the areas with sugarcane, through a comparative and systematic analysis. The present work was conducted in the company USACIGA - Sugar, Alcohol and Electric Power S.A. located at Gaucha, northwest Parana state. Treatments constituted of areas cultivated with sugarcane and submitted to different times of stillage application, respectively 1, 2, 3, 4, 12 and 20 years, and a reference area, without application. In all the studied areas trenches of 1 m3 were opened, geo referenced in 340 m of altitude for accomplishment of the soil classification and sample collection. The evaluations were performed of the density, soil particle density, organic carbon, cation exchange capacity (CEC), total porosity, soil water moisture for the sugarcane, besides the relationships among K, Ca, Mg and V%. The results indicated that the stillage application contributed to the organic carbon and potassium increase in the soil and that the sugarcane productivity presented a direct relationship with the ratio of potassium adsorption increase in the soil. |
