Role of nitrogen fixing trees in mixed forest Ⅲ Leaf litter decomposition and its N release of nitrogen fixing tree species

Abstract

Abstract: Studies on the leaf litter decomposition and its N release of 11 N-fixing and non-N-fixing tree species showed that the biological decay coefficient of leaf litter, the dry weight loss of leaf litter during its decay, and the N release from the leaf litter of N-fixing tree species were 1.3, 1.5 and 8.2 times higher than those of non-N-fixing ones, respectively.

Key words: Nitrogen-fixing tree species, Leaf litter decomposition, N release, vegetation type, water reservoir, green belt, Shanghai, soil, central urban area
