Dinamica del carbono organico en tepetates cultivados
Indurated volcanic soils (tepetates) of the Mexican Altiplano display thick columnar horizons, hard laminar horizons, and grey mottles at depth. X-ray diffraction (XRD) studies show a relative enrichment in cristobalite vs. halloysite in the indurated plates of the laminar horizons and in the clay fraction of the mottles. Transmission electron micr...
The agricultural rehabilitation of tepetates, indurated and sterile volcanic tuffs located along the mexican neovolcanic ridge, is technically possible. However, it is necessary to know in detail the agro-socioeconomical factors of the peasant communities which have these kind of lands, to give them technical answers appropiate to local realities. ...
