Values of δ¹³C of dried rice plants obtained from planted microcosms without (control) and with addition of ¹³C-labeled RS.

Abstract

<p>RS I and RS II denote the two treatments, the δ¹³C of rice straw applied was 213.0‰ and 474.7‰ for RS I and RS II, respectively; means ± standard deviation (SD) (n = 3). The differences between the treatments over time were examined using Duncan <i>post hoc</i> test of a one-way ANOVA. Different letters on the top of bars indicate significant difference (<i>P</i><0.05) between the data.</p
