A study concerning the determination of liquid limit was conducted for two types of Latosols. Four methods of determination were used: Casagrande, Casagrande one-point, cone penetrometer and one-point cone penetrometer. The liquid limit was analyzed for both the soils: one originated from the City of Viçosa, MG (with high content of clay particles) and another from Paraopeba, MG (sandy clay loam). The soil from Viçosa presented high values of liquid limit in all methods. Among the used methods, only the one-point Cone Penetrometer method presented a significant difference. There was no significant difference in the determination methods of liquid limit for the other soil. Thus, the content of clay size in the soil has an influence on the methods of determination of the liquid limit.
