Linear regression between pesticide values and soil properties. (A) Correlogram showing the relationship among physical–chemical soil properties and GLY and AMPA values. Positive correlations are displayed in blue and negative correlations in red color. Color intensity and the size of the circle are proportional to the correlation coefficients. (B) Canonical variation (%) of the principal axis on canonical correlation analysis among soil properties and pesticides values using the significant correlate parameters. NT no-tillage farms, SF secondary forest.
