Effect of Species, Source of Litter, Type of Soil, and Climate on Litter Decomposition: Microbial Decomposition of Tree and Shrub Leaf Litter 3

Oikos, 1980
The effects, on leaf litter decomposition, of species (birch and oak), site on which the trees grew (mull or mor), soil type on which the litter decomposed, and the climates of the two sites, were studied in 1967/69 and 1968/70. The most consistent main effect was species, and significant effects of species on weight loss, respiration, and total N were

Decomposition of bracken litter

Botanical Journal of the Linnean Society, 1976
Investigations on the decomposition of bracken petioles, over a five-year period on six adjacent soil types, including moder-type humus, mull and peat, are reviewed.

Decomposition of Fine Root and Woody Litter

2003
Decomposition of wood and fine root litter is much less studied than that of foliar litter. This chapter gives a brief overview to a few representative studies, giving some method approaches. For logs, there are decomposition classes given, which allow a description of the process.

Heavy metals and litter decomposition in coniferous forests

2002
The dynamics of Mn, Zn, Fe, Cu, Pb, and Cd during litter decomposition was studied to understand how litter and soil metal concentrations influence the accumulation and/or the release of metals. Three types of leaf litters (green and brown leaves of Populus tremula L., green leaves of Betula pubescens Ehrh.) and four types of needle litters (green and ...

A model of savanna litter decomposition

Ecological Modelling, 1982
Abstract A model of litter decomposition in a South African savanna is described. Decomposing material is divided into a number of particle classes, distinguishing material of different ages, origins and size. Each particle class is further divided into a number of chemical constituents.

Methods for Estimating Litter Decomposition

2008
Litterfall in terrestrial ecosystems represents the primary pathway for nutrient return to soil. Heterotrophic metabolism, facilitated through comminution by small insects and leaching during precipitation events, results in the release of plant litter carbon as CO2 into the atmosphere.

Decomposition of Cones and Woody Litter

2020
Wood is a major component of forest biomass but woody litter has been difficult to study because of its enormous range in size and its temporally erratic input due to both natural and human-caused events. Cones also are erratic in their input to the forest floor as litter but can sometimes represent a large percentage of organic matter input.

Measurement of Leaf Litter Decomposition

1999
Decomposition is a complex and multistep process of litter breakdown through leaching, mechanical and invertebrate fragmentation, and transformation through the activity of soil microorganisms (Swift et al. 1979). The rate of litter decomposition varies with chemical composition, abiotic factors and biotic factors (Singh and Gupta 1977).

Soil Respiration and Litter Decomposition

2003
Emissions of CO2 from the organic and mineral soil horizons into the atmosphere are considered a good representation of soil respiration (R soil) when the diffusion-driven losses to the atmosphere are at equilibrium with the biological rates of CO2 production (Hanson et al. 2000). R soil is the net effect of the biological activity of autotrophic roots
