Abstract

Vinasse can promote better fertility when deposited in the soil, but the amounts should not exceed its capacity of ions retention that can promote leaching, contaminating the environment. The objective of the work was to evaluate the mobility of nutrients in different soils and their leachate, treated with filter cake and vinasse. The experimental design used to the incubation consisted on a factorial scheme of 2 x 4 x 2 to the soil, levels and pH, with application rates of 0, 50, 100 and 150 m3/ha-1. The addition of the filter cake served as a corrective to the soils. The levels of pH, calcium, magnesium and potassium in the soil increased with application of filter cake and vinasse, influencing the values of cations exchange capacity and bases saturation. The potency values of exchangeable potassium showed percentage greater than 5%, demonstrating the risk degree to salinity. Key words: Leachate. Filter Cake. Vinasse. Nitosol. Argisol. Application Rates.
