Rapid leaf decay and nutrient release in a chinese tallow forest
Summary The Chinese tallow tree, Sapium sebiferum, was introduced to the Texas Gulf Coast in the early 1900's and has spread into coastal prairie habitats. Since coastal prairie contains few deciduous trees, we studied leaf fall dynamics, rate of decomposition, and the quantity and rate of nutr...

| 520 | |a Summary The Chinese tallow tree, Sapium sebiferum, was introduced to the Texas Gulf Coast in the early 1900's and has spread into coastal prairie habitats. Since coastal prairie contains few deciduous trees, we studied leaf fall dynamics, rate of decomposition, and the quantity and rate of nutrient input from decomposing tallow leaves. Among-year leaf fall averaged 382.6 g·m-2·yr-1, similar to other south temperat deciduous forests and about as predicted by Meentemeyer et al.'s (1982) AE-lignin model. Decay of tallow leaves (k=-4.33) was much more rapid than native black willow (k=-0.35) and than other temperate deciduous trees (k=-0.77). The ratio of lignin to initial nitrogen concentration, highly correlated with rate of decomposition for hardwood trees, was low for Chinese tallow and may contribute to rapid leaf decay. Taking AE and lignin content into account, Meentemeyer's (1984) model predicted k=-1.39 for Chinese tallow and k=-0.88 for black willow. Decay of tallow was much faster but decay of willow was slower than predicted, suggesting that decay on the coastal prairie may be controlled by factors other than lignin content and climate. N, P, and K characteristically accumulate as leaves decay. However, these elements did not accumulate as tallow leaves decayed, possibly because high densities of Armadillidium vulgare, a detritivore, reduced immobilization of elements by microbes. This would result in increased turnover of these elements. Accumulation of Al, Fe, Zn, and S in decaying tallow litter may be related to flood-drain cycles on coastel prairie clay soils. Ca, N, K, Mg, and S were added to forest soil in greatest amounts from decaying tallow leaves. Concentrations of P, K, NO3−N, Zn, Mn, and Fe were significantly higher and Mg and Na were significantly lower in forest than in prairie soil, raising the possibility that Chinese tallow trees altered the distribution of nutrients in the soil profile. We conclude that the Chinese tallow tree may enhance productivity in ecosystems to which it has been introduced by addition of nutrients from rapid decay of leaves. | ||

Rapid leaf decay and nutrient release in a chinese tallow forest |
| abstract |
Summary The Chinese tallow tree, Sapium sebiferum, was introduced to the Texas Gulf Coast in the early 1900's and has spread into coastal prairie habitats. Since coastal prairie contains few deciduous trees, we studied leaf fall dynamics, rate of decomposition, and the quantity and rate of nutrient input from decomposing tallow leaves. Among-year leaf fall averaged 382.6 g·m-2·yr-1, similar to other south temperat deciduous forests and about as predicted by Meentemeyer et al.'s (1982) AE-lignin model. Decay of tallow leaves (k=-4.33) was much more rapid than native black willow (k=-0.35) and than other temperate deciduous trees (k=-0.77). The ratio of lignin to initial nitrogen concentration, highly correlated with rate of decomposition for hardwood trees, was low for Chinese tallow and may contribute to rapid leaf decay. Taking AE and lignin content into account, Meentemeyer's (1984) model predicted k=-1.39 for Chinese tallow and k=-0.88 for black willow. Decay of tallow was much faster but decay of willow was slower than predicted, suggesting that decay on the coastal prairie may be controlled by factors other than lignin content and climate. N, P, and K characteristically accumulate as leaves decay. However, these elements did not accumulate as tallow leaves decayed, possibly because high densities of Armadillidium vulgare, a detritivore, reduced immobilization of elements by microbes. This would result in increased turnover of these elements. Accumulation of Al, Fe, Zn, and S in decaying tallow litter may be related to flood-drain cycles on coastel prairie clay soils. Ca, N, K, Mg, and S were added to forest soil in greatest amounts from decaying tallow leaves. Concentrations of P, K, NO3−N, Zn, Mn, and Fe were significantly higher and Mg and Na were significantly lower in forest than in prairie soil, raising the possibility that Chinese tallow trees altered the distribution of nutrients in the soil profile. We conclude that the Chinese tallow tree may enhance productivity in ecosystems to which it has been introduced by addition of nutrients from rapid decay of leaves. |
