摘要

A soil survey in the title area was conducted at two sites to investigate morphological, physical and chemical properties. The sites were Guerrero Negro and Jesus Maria. They were highly affected by Quaternary aeolian deposits. The soil texture of Guerrero Negro was sandy (Psamment, Aridic Arenosol). The sands of the area were transported and sedimented by the influence of a lagoon. The topsoil was light yellowish in colour with no accumulation of organic matter. The second horizon was a hard brownish red layer with an abundance of gypsum. These two layers contained illite, kaolinite and smectite. The contents of illite and kaolinite were much higher than smectite. The third layer was greyish yellow and composed of calcite. The soil texture of theJesus Maria site was clay-like and slightly weathered, with slightly stronger weathering in the upper layer than in the lower layer. The soil classification of this site corresponded to Orthent or Aridic Calcisol. The dry climate of the area resulted ina highly developed topsoil structure as indicated by the rich clay contents. The lower layer had no particular structure. The soil profile of the site was mainly smectite. Deflocculation of the smectite, leading to the blockage of pores, resulted in hardening of the soil profile. These findings suggested that the various soil profiles in central Baja California, Mexico, contain different deposits.
