Prácticas agroforestales y especies de uso múltiple para la rehabilitación y conservación de suelos volcánicos en Adolfo López Mateos, Tlaxcala: percepción de los agricultores

Abstract

Abstract. During 2003 and 2004 in the Adolfo López Mateos community, Tlaxcala, the agroforestry practices to rehabilitate and conserve soils were characterized, and later with farmers’ participation, identified the species of multiple purpose that best fit with these practices. The plantation of succulent and/or woody species in contour hedgerows, together with dense herbaceous groundcover and excavation of infiltration trenches, was identified as the most widespread practice. Key factors are the selection of species to guarantee physical stability, and seemingly able to promote biological and chemical interactions; however, the major shortcome is the human over-utilization of these species to profit of their byproducts.
