Nitrogen availability indexes
Web10 de ago. de 2009 · There are two main reasons why foliar δ 15 N might index soil N availability to plants. First, when N availability is high, N lost from the ecosystem is more likely to be depleted in 15 N, which increases the δ 15 N of leaves. When N availability is low, N is cycled and lost primarily as organic N ( Hedin et al ., 1995; Neff et al ., 2003 ). WebOn the grounds of correlation analysis, it can be concluded that biological index of nitrogen availability achieved by the anaerobic incuba- tion (without substraction of the initial …
