Abstract The litters in the forest floor are the principal contributor for regulating the cycling of necessary elements, primary productivity and maintain soil fertility within the forest ecosystems. Therefore, this study was conducted in a deciduous forest of Bangladesh to ascertain the leaf-litter production and decomposition along with elemental dynamics (K, Ca, Mn, Fe, Co and Zn). Leaf-litter samples from five deciduous plant species and soil samples were collected from the Madhupur Sal Forest for about six months (July-December) in 2018. Production of leaf-litter during the dry season (December) was found in an order of Shorea robusta>Dipterocarpus indicus>Terminalia bellirica>Tectona grandis>Grewia microcos. The decomposition rates were higher for the long sampling period (90 days) followed by the intermediate (60 days)> short(30 days) sampling period. The nutrient release pattern from the leaf-litter was similar (Ca>K>Mn>Fe>Zn>Co) for all plant species except for Terminalia bellirica and Tectona grandis. The Pearson correlation coefficients showed a significant relationship between K and Fe (r=0.54; p<0.05), Ca and Co (r=0.59; p<0.01), Fe and Co (r=0.97; p<0.05) in leaf-litters. Analysis of variance (ANOVA) revealed significant variation in the litter production, decomposition and nutrient content (except Zn; p>0.05) among the different plant species (p<0.05). There revealed a significant dynamic of necessary elements from soil to trees and vice-versa.

Litter Mixing

Coastal wetlands are among the most carbon-rich ecosystems in the world. Litter decomposition is a major process controlling soil carbon input. Litter mixing has shown a non-additive effect on the litter decomposition of terrestrial plants particularly of those species having contrasting litter quality. But the non-additive effect has been rarely tested in coastal plants which generally having low-quality litters. We selected three common mangrove species and one saltmarsh species, co-occurring in subtropical coasts, to test whether the non-additive effect occurs when the litters of these coastal species mixing together. We are also concerned whether the changes in the decomposition rate of litter will affect the nutrient contents in waters. A litter-bag experiment was carried out in a glasshouse with single and mixed leaf litters. A non-additive effect was observed in the litter mixtures of mangrove species Aegiceras corniculatum vs. Kandelia obovata (antagonistic) and A. corniculatum vs. Avicennia marina (synergistic). Whereas, the mixture of A. corniculatum (mangrove species) and Spartina alterniflora (saltmarsh species) showed an additive effect. The strength of the non-additive effect was unrelated to the initial trait dissimilarity of litters. Instead, the decomposition rate and mass remaining of litter mixtures were strongly related to the carbon concentrations in litters. Nutrient content in waters was dependent on the decomposition rate of litter mixtures but not on the initial nutrient concentrations in litters. Despite the behind mechanisms were not yet revealed by the current study, these findings have improved our understanding of the litter decomposition of coastal species and the consequent nutrient release.
