SANDOVAL GARCIA, Celestino et al. Effect of different land use in the physical and hydrological properties of a Luvisol in the state of Oaxaca. Rev. mex. de cienc. forestales [online]. 2021, vol.12, n.68, pp.151-177. Epub 28-Feb-2022. ISSN 2007-1132. https://doi.org/10.29298/rmcf.v12i68.982.
Changes in land use in the southern sierra and coast of Oaxaca have caused the deterioration of the forest ecosystem. Thus, given the scarce information on their impact on soil properties, the objective was to evaluate the effect of different land uses on the physical and hydrological properties of a Luvisol. The treatments evaluated were: pasture, agricultural, forest plantation, pine forest (control), and agricultural-livestock, located in the micro-watershed of the La Venta River, Copalita, Oaxaca. The parameters measured in the field were: hydraulic conductivity (K), bulk density (AD), total porosity (Po), which were obtained in undisturbed soil samples, mechanical resistance to penetration (MRP), initial infiltration (I a ), cumulative infiltration (I b ) and infiltration capacity (I c ). The determination of sand (S), silt (Si) and clay (Cl) particles, field capacity (FC), permanent wilting point (PWP), and available water (Aw) was performed on eight disturbed samples (four per depth) at each use, for a total of 40. Significant differences were observed in Po, MRP, AD, K, FC, PWP, Aw, and in the proportion of sand between land uses. K exhibited a significant positive correlation (p≤0.05) with PWP, Aw, S, I a , I b , and I c ; the last three were positively correlated. Agricultural, pasture and agricultural-livestock uses showed more negative impacts on infiltration and hydraulic conductivity, as well as on apparent density, porosity, mechanical resistance, and water availability; the forest plantation had a positive effect on the evaluated properties.
