LEAF LITTER DECOMPOSITION PDF


Litter and lignin decomposition was more rapid in stand-representative litter from multispecific stands than in litter from pure beech stands.

International Journal of Forestry Research

Except for beech litter, the decomposition rates of species-specific tree litter did not differ significantly among the stand types, but were most rapid in Fraxinus excelsior and slowest in beech in an interspecific comparison.

Decomposition of stand-representative litter mixtures displayed additive characteristics, not significantly more rapid than predicted by the decomposition of litter from the individual tree species.

Leaf litter decomposition rates were positively correlated with the initial N and Leaf litter decomposition concentrations of the litter, and negatively with the initial C: The results support our hypothesis that the overall decomposition rates are mainly influenced by the chemical composition of the individual litter species.

Thus, the fraction of individual tree species in leaf litter decomposition species composition seems to be more important for the litter decomposition rates than tree species diversity itself.

Despite its essential role in carbon and nutrient cycling, the temperature sensitivity of leaf litter decay in tropical forest ecosystems remains poorly resolved, especially in tropical montane wet forests where the warming trend may be amplified compared to tropical wet forests at lower elevations.

We quantified leaf litter decomposition rates along a highly constrained 5. Dominant vegetation, substrate type and age, soil moisture, and disturbance history are all nearly constant across this gradient, allowing us to isolate the effect leaf litter decomposition rising MAT on leaf leaf litter decomposition decomposition and nutrient release.

Our estimate of the Q10 temperature coefficient for leaf litter decomposition was 2. The lack of net N immobilization during all three litter collection periods at all MAT plots indicates that N was not limiting to leaf litter decomposition, regardless of temperature. Litter improves soil quality through adding the organic matter and nutrients to the soil [ 15 — 17 ].

  • INTRODUCTION

Leaf litter is the main and fastest source of organic matter and nutrient to the soil compared to other litter types [ 618 leaf litter decomposition, 19 ]. The nutrients in litter were added to the soil through microbial decomposition and physical leaching of soluble components followed by microbial oxidation of refractory components [ 1820 — 22 ].

However, the amount of nutrient addition through litter decomposition varies from species to species [ 2023 leaf litter decomposition, 24 ]. The amount of nutrient addition to a particular ecosystem was found to vary with the species [ 2025 ] and other climatic conditions [ 132026 ].

Appropriate tree species selection based on nutrient cycling is a vital issue in agroforestry practice.

However, no leaf litter decomposition has been taken to screen or prioritize the commonly planted tree species in the cropland agroforests as well as other types of agroforestry on the basis of nutrient cycling.

The objectives of this study were to determine the following: Materials and Methods 2. Description of the Study Area Bangladesh is bordered by the Bay of Leaf litter decomposition on the south and India on all the other sides except for a small section of Myanmar.

During the period of experiment no agricultural cultivation was carried out in that cropland. A tropical to subtropical monsoon climate characterizes this region with three distinct seasons, that is, summer March—Mayrainy June—Octoberand leaf litter decomposition November—February.

The monthly average rainfall is mm. The highest average leaf litter decomposition mm occurs from June to September and the lowest average rainfall 16 mm occurs in the months leaf litter decomposition November to February.

January is the coldest month and May is the warmest month. Leaves of individual species were thoroughly mixed.

Experimental Design Decomposition of leaf litter was determined using the litter bag technique [ 6 ]. The litter bags were placed on December 1, for dry season and June 1, for wet season in the cropland. Sample Collection and Processing Ten bags were collected for each species at every day interval for the initial 30 days and subsequently at, and day interval for the remaining periods.

We hypothesized that changes in leaf litter decomposition type would result in variations in the rate but not the temporal dynamics of leaf litter decomposition at a local scale, reflecting the effects of litter chemistry and prevailing climate conditions of the region. It is in a transitional zone from warm temperate to northern sub-tropic climate.
