It was evaluated in the field the infiltration of water in the soil in three different cultures and also native forest in the city of Cáceres - MT. The basic infiltration velocity (VIB) of the soil was defined through the ring infiltrometer method and to determine the parameters of the accumulated infiltration equation (I) and infiltration velocity (VI) the empirical model developed by Kostiakov was used. In the study areas (SPC; SLF; SP and FN) three infiltration tests were carried out. The results were subjected to analysis of variance and comparison of means, and showed that soils with corn crops and native forest showed better water infiltration.
