%X changes of the satured hydraulic conductivity in a soil was estimated using the ˇ°falling headˇ± and ˇ°point sourceˇ± methods. the soil treated with vinasse was an ustipsamment typic sandy isohipertermic located at the experimental center of the national university of colombia at palmira (3ˇă 25' 39.81" n, 76ˇă 25' 45.70" w; 953 m.a.s.l., 24 ˇăc, 60% rh. and 1020 mm.). the field methods used did not show statistical differences for the estimation of the satured hydraulic conductivity (p<0.05). however, a decreasing exponential relationship between hydraulic conductivity and vinasse concentration was found. the hydraulic conductivity was reduced about of 50% from the initial value to 2ˇă brix in a sandy soil, 5.3ˇă brix to a sandy loam soil and 6.1ˇă brix to a clay loam soil.
