Resumo
Usually stillage presents high concentrations of nitrate, potassium and organic matter. Its utilization may change a soil’s
characteristics and modify its chemical properties, increasing the availability of some elements for plants. On the other
hand, stillage may also promote change in physical properties of soil in two different ways: these changes can improve
soil aggregation, increasing soil water infiltration capacity and, consequently, increasing leaching of ions, in such a way
to contaminate the groundwater when in high concentrations, as well as to promote dispersion of soil particles, contributing
for a decrease in its infiltration rate and elevation of runoff, with possible contamination of surface water. Due to the
fact that there are different types of soil and stillage composition, the research results found are very variable, however,
agreement exists that its application must be made according to cation exchange capacity of soil.
