Soil chemical data is necessary for predicting the crops potential yield. The objective was to characterize the soil of the municipalities of Almoloya, Apan and Emiliano Zapata in the State of Hidalgo, Mexico in terms of physical-chemical-metal parameters. The following variables were determined in the soilsamples; pH, electrical conductivity (EC), redox potencial (Eh), zeta potential (.), soil moisture, ash content, organic matter (OM), inorganic nitrogen (IN), organic nitrogen (ON), total nitrogen (TN), soil texture, cation exchange capacity (CEC) and the following metals Ca, Mg, K, Fe, Ni, Cd, Pb and Mn. The pH varied from a range of 6.30 in Almoloyas soil to 6.80 in Apans soil. The EC was higher in Emiliano Zapatas soil with a value of 0.35 dSmG . The Eh was in a range of -19.84 mV observed in Almoloya soil through -29.90 mV in Apan soil. 1 The (.) was -18.73 mV in Emiliano Zapatas soil and -25.24 in Almoloyas soil. The Na, K and Mg concentrations were highest in Apan soils with 30.95, 17.34 and 6.27 mg kgG respectively, while Ca (69.27 mg kgG ), Pb (1.041 1 mg kgG ) and Ni (0.42 mg kgG ) concentrations were highest in Emiliano Zapatas soil.
