The contentious nature of soil organic matter
Johannes Lehmann,Markus Kleber +1 more
TL;DR: It is argued that the available evidence does not support the formation of large-molecular-size and persistent ‘humic substances’ in soils, and instead soil organic matter is a continuum of progressively decomposing organic compounds.
Journal ArticleDOI
Climate, leaf litter chemistry and leaf litter decomposition in terrestrial ecosystems : a triangular relationship
TL;DR: In this paper, the authors analyzed first-year leaf litter decomposition data from 44 locations, ranging from cool temperate sites to humid tropical sites, and found that the control of AET on litter decomposability is partly mediated through an indirect effect of Aet on litter chemistry.
Journal ArticleDOI
Stabilization and destabilization of soil organic matter: mechanisms and controls
TL;DR: In this article, a conceptual model of the processes by which plant leaf and root litter is transformed to soil organic C and CO 2 is presented, which is viewed as resulting from three general sets of characteristics.
Journal ArticleDOI
Biodiversity and Litter Decomposition in Terrestrial Ecosystems
TL;DR: Empirical and theoretical evidence is explored for the functional significance of plant-litter diversity and the extraordinary high diversity of decomposer organisms in the process of litter decomposition and the consequences for biogeochemical cycles.

Global-Scale Similarities in Nitrogen Release Patterns During Long-Term Decomposition
William J. Parton,Whendee L. Silver,Ingrid C. Burke,Leo Grassens,Mark E. Harmon,William S. Currie,Jennifer Y. King,E. Carol Adair,Leslie A. Brandt,Stephen C. Hart,Becky Fasth +10 more
TL;DR: It is suggested that fundamental constraints on decomposer physiologies lead to predictable global-scale patterns in net N release during decomposition.

Nitrogen and Lignin Control of Hardwood Leaf Litter Decomposition Dynamics
TL;DR: The effects of initial nitrogen and lignin contents of six species of hardwood leaves on their decomposition dynamics were studied at the Hubbard Brook Experimental Forest by inverse linear relationships between the percentage of original mass remaining and the nitrogen concentration in the residual material.

Influence of climate, soil moisture, and succession on forest carbon and nitrogen cycles
John Pastor,Wilfred M. Post +1 more
TL;DR: In this article, a computer simulation that assembles a model ecosystem which links these biotic and abiotic interactions through equations that predict decomposition processes, actual evapo-transpiration, soil water balance, nutrient uptake, growth of trees, and light penetration through the canopy.

Forest Litter Decomposition in Relation to Soil Nitrogen Dynamics and Litter Quality
TL;DR: Decomposition and changes in nitrogen and organic—chemical content of six types of forest litter were studied for 2 yr in five adjacent Wisconsin forests, finding that slowly disappearing acid—soluble and acid—insoluble substances dominated the pattern of mass loss in all litters.

Nitrogen immobilization in decaying hardwood leaf litter as a function of initial nitrogen and lignin content
John D. Aber,Jerry M. Melillo +1 more
TL;DR: Patterns for important species from Douglas-fir forests of the Pacific Northwest are quite different and may reflect differences in nitrogen availability following disturbance, and similar trends were found for southeastern hardwoods.
