ResumoThe objective of this study was to investigate possible effects of soil contamination from pollution by urbanization and inordinate use of the course on the shores of the Sanga Lagoão of Ouro through soil chemical variables analyzed with multivariate statistical tools. We established five sampling points in the path of urban Sanga that have different uses and management. Alterations in the characteristics of soil in accordance with the management imposed. Similarity was observed the formation of three patterns chemical characteristics: soil fertility (1), acidity (2), and the amount of MO, N and K (3) in the soil. Four factors (represented by F1, F2, F3 and F4), explained 88.34% of the total variation of the data, and the factor F1 is the greatest explanation of the variance, with 48% and group characteristics related to soil fertility. In the correlation matrix of variables 38.6% of the correlations are significant indicating a good fit for factor analysis.
