Fig. 3. Scatter plot of first and second canonical variates (Can) of a canonical discriminant analysis procedure using 21 soil variables to discriminate plots by land-use type in Baltimore (R = residential, CT = commercial or transportation, IU = industrial or urban open, P = park or golf course, I = institutional, and F = forest). The first canonical variate was correlated to P, K, and bulk density and the second variate to pH. Piedmont plots are the solid symbols and the star sign, and the Coastal Plain plots are the open symbols and the plus sign.
