Redução de perdas de água por percolação em canais de terra utilizando a vinhaça.

Abstract

To study the effect of the vinasse application on water seepage, an experiment was conducted on static irrigation channels at the Coruripe Sugarnills, in the State of Alagoas, Seepage of vinasse, residual water and irrigation water was detemined on non pre-treated and vinasse pre-treated irrigation channels. On the non-pretreated channels, the degree of seepage depended on the fluid characteristics. The vinasse pre-treatment increased the global density of the soil and therefore their porosity, responsible for the seepage, decreased. The seepage of fluids after the pre-treatment depended on the characteristics of these. High doses of vinasse eliminated the probable dispersant effect caused by the first application of vinasse.
