Abstract


Changes in soil properties were evaluated in a temperate forestlocated in the town of San Mateo Acaxochitán, Hidalgo, Mexico. Soilsamples were taken at four depths in two periods (2004, S-04 and 2011, S-11) to the results we applied the principal component analysis, thecomponent one explained 51 % of variance; presented positive correlationbetween the variables S-04K, S-11NT, S11CO, S-04NT and S-04CO (groupa), S-11pHact, S-04Da , S-04Ca , and S-04Mg (group b) and negativecorrelation between the variables: S-11Da, S-11Alint, S-11Dr, S-11Acint, andS-11PT (group c), and S-11C/N and S-04C/N (group d). The componenttwo explained 31 % of variance , presented positive correlation between thevariables: S-11PT, S-11Acint, S-04Mg , and S- 04Ca (group c) and negativecorrelation between S-04C/N and S-11C/N (group d). The analysis ofvariance showed that the soil variables that showed significant differences (? 0.05 ) between the S-04 and S-11 were: PT, Dr, pHpot , Acint , NT , K+ andCa2+
