<p>Notes: Soil type data from NRCS Soil Surveys for Polk and Benton Counties. Soil chemical variables reflect means of five control plots sampled to 10 cm depth, with standard errors in parentheses. Site differences in chemical variables were analyzed using one-way ANOVA. Values in columns followed by different letters are significantly different (p<0.05) by Tukey post-hoc comparison.</p
