Integrating stand and soil properties to understand foliar nutrient dynamics during forest succession following slash-and-burn agriculture in the Bolivian Amazon.

The multiple regression model of soil δ 15 N which included soil depth was highly significant ( R 2 = 0.23, P = 0.0285, N = 38), and showed a negative and positive relationship between soil δ 15 N and stand age ( t -ratio = −2.07, F -ratio = 4.29, P -value = 0.0459) and depth ( t -ratio = 2.25, F -ratio = 5.08, P -value = 0.0307), respectively, and no significant interaction (although see Figure 6 for trend).

A negative trend was identified between soil base saturation and stand age ( R 2 = 0.29, P = 0.0854, N = 11).
