Abstract

Few studies on soil genesis have been done in México due to the lack of good quality soil surveys and reduced data for its classification and interpretation. The objective of the present research was to explain the genesis and evolution of the soils of the former lake Texcoco, México, using their taxonomy, formation of pedofeatures, and the anthropogenic influence, as support tools, and using as reference the land classes occurring at Atenco and Montecillo (Texcoco), State of México. Twenty soil profiles were studied; it was found that the soils have a lacustrine-alluvial origin, thus being classified as Entisols. However, the accumulation of organic matter is developing Mollisols, or Vertisols, when the clay sediments are deep (>50 cm). In these soils the anthropogenic influence has been mainly on their process of desalinization.
