YANEZ DIAZ, María Inés; CANTU SILVA, Israel y GARZA OCANAS, Fortunato. Effect on the physicochemical properties of a Regosol from land use change. Rev. mex. de cienc. forestales [online]. 2023, vol.14, n.79, pp.58-79. Epub 06-Oct-2023. ISSN 2007-1132. https://doi.org/10.29298/rmcf.v14i79.1359.
Soils provide ecosystem goods and services that are affected by the loss of their fertility; land use changes aimed at recovering areas or reducing degradation have a positive influence on their properties. This study was conducted in a Regosol soil in Galeana, Nuevo León, where physical (texture, bulk density, and mechanical resistance to penetration) and chemical properties (pH, electrical conductivity, and organic matter) were evaluated at two depths (0-5 and 5-30 cm) in a pine forest, reforestation area, agricultural use, and grassland. The results showed no significant differences in most of the properties evaluated between soil uses and depths. Mechanical resistance to soil penetration was one of the most susceptible variables for agricultural use (8.25 kg cm-2), as opposed to forest (22.5 kg cm-2). The pH did not show changes between soil uses, while it increased and showed differences between depths with a mean of 7.75 (0-5 cm) and 7.81 (5-30 cm), and there were no salinity issues (0.17 dS m-1). The organic matter (OM) content showed a recovery trend in the order of grassland>pine forest>reforestation>agriculture. Texture was classified as loam, with differences in sand content for the depth factor and silt content in the 5-30 cm stratum between the different land uses. It is concluded that land use changes focused on reclamation can improve the quality of Regosol.
