The aim of this work was to characterize a dystroferric Red Latosol in terms of its physical-hydric properties. Soil sampling was carried out in an agricultural cultivation area in the experimental field of the State University of Mato Grosso (UNEMAT) in Tangará da Serra - MT. Deformed and undisturbed soil samples were collected in the 0-10, 10-20, 20-30, 30-40 and 40-50 cm layers. The soil attributes analyzed were texture, soil density, volumetric moistu- re, macroporosity, microporosity, total porosity, field capacity, permanent wilting point, soil penetration resistance, available water capacity, total water availability and basic infiltration velocity. Analysis of variance and comparison of means were performed for each variable evaluated (Tukey p<0.05). The dystroferric Red Latosol at the study site has a very clayey texture. For the clay content found, the critical density is 1.34 kg dm-3. The field capacity of the soil is 0.3490 m3 m-3, the permanent wilting point is 0.2083 m3 m-3, and the available water capacity is 82.45 mm. The penetration resistance of the soil found classifies it as having moderate resistance. The soil basic infiltration velocity (BIV) was 25.91 mm h-1, classified as high BIV.
