Infiltration process is influenced by soil and vegetation management practices in areas of grasslands. In the state of Zacatecas, Mexico, native grass¬lands take up over 70 % of the surface. One of the main problems is the loss of soil cover caused by overgrazing. Three treatments were applied in order to assess the impact of different infiltration managements: a) exclusion of grazing (E), b): exclusion + aerator roller (E+R), and c): continuous grazing (PC) in two sites of medium open grassland: Viboritas and Benito Juarez, Zacatecas, Mexico. Infiltration rate was obtained using a rain simulator type Asseline. Results showed that both sites the average of infiltration rate of treatment PC (27.0 mm•h-1) were not significantly different (P≤0.01) to the infiltration rate of treatment E (32.6 mm•h-1) and E+ R (30.3 mm•h-1).
