AVILA-CAMPUZANO, Gabriela Rebeca et al. Reforestation assessment in the formation of soil from tepetates. Rev. Chapingo ser. cienc. for. ambient [online]. 2011, vol.17, n.3, pp.303-312. ISSN 2007-4018.

In 1973 the Commission of the Lake Texcoco Plan initiated a soil and water conservation program, through the reforestation of the hilly zone and restoration of the grassland in the low areas in the lands of the former lake bed. It has been 37 years, and there are few studies that assess the direct impact of reforestation on soil formation and the recovery of its functions as part of the ecosystem. The present study was conducted in the eastern part of the State of Mexico, in order to evaluate the impact of different forest plantations (cedar, eucalyptus, pines and casuarinas) on soil formation in a red tepetate area. Three soil profiles were described for each planting, and physical, chemical and micromorphological analyses were carried out. Results show that casuarinas and cedars are the species that contribute the most to soil formation and increase the water retention capacity in the area. Although pines and eucalyptus adapt favorably to these environmental conditions, their influence in environmental restoration is considerably lower.
