Physical, chemical, isotopic and biological properties of bulk mineral soils (0–15 cm).

<p>Values are means and 1 SE (in parentheses) for watershed-level composited samples for bulk density (<i>n</i> = 10); texture (<i>n</i> = 5); pH (<i>n</i> = 15); %C, %N, δ¹³C and δ¹⁵N (<i>n</i> = 8); and Brays-P (<i>n</i> = 15); and root biomass (<i>n</i> = 5), where the sample size (<i>n</i>) refers to the number of plots. For pH, the mean was calculated by averaging hydrogen ion concentrations followed by log10 back transformation. The values in parentheses are quadratic ranges. P-values are the results of two-sided t-tests.
