Effect of N deposition on decomposition of plant litter and soil organic matter in forest systems
Björn Berg,Egbert Matzner +1 more
TLDR
Initial decomposition is generally higher for N (nutrient) rich plant litters than for litters with a lower N (Nutrient) content, and in later stages, at which lignin-degradation rates regulate litter decomposi...Abstract:
The effects of nitrogen (N) deposition on plant litter and soil organic matter decomposition differ depending on the stage of decomposition (early, late, and final stages). The effects can be divid...read more

The effects of long term nitrogen deposition on extracellular enzyme activity in an Acer saccharum forest soil
TL;DR: In this article, the authors investigated microbial community responses to long-term anthropogenic N deposition in a sugar maple-dominated forest in northern Michigan during the 1998-2000 growing seasons.

TL;DR: A meta-analysis suggests that nitrogen deposition impedes organic matter decomposition, and thus stimulates carbon sequestration, in temperate forest soils where nitrogen is not limiting microbial growth as mentioned in this paper, and the concomitant reduction in soil carbon emissions is substantial, and equivalent in magnitude to the amount of carbon taken up by trees owing to nitrogen fertilization.

TL;DR: In this article, the experimental evidence for long-term carbon (C) sequestration in soils as consequence of specific forest management strategies was reviewed, and the effects of harvesting, thinning, fertilization application, drainage, tree species selection, and control of natural disturbances on soil C dynamics were analyzed.
Journal ArticleDOI
Phenol oxidase, peroxidase and organic matter dynamics of soil
TL;DR: In this article, a multiple regression model was used to investigate the relationship between pH and phenol oxidase and peroxidase activity in soil organic matter, and the results showed that high in situ oxidative activities limit organic matter accumulation and low in situ oxidase activity promotes organic matter storage.

HUmus Chemistry Genesis, Composition, Reactions
TL;DR: In this paper, the authors present an analysis of organic matter in soil using NMR Spectroscopy and analytical pyrolysis, showing that organic matter is composed of nitrogen and ammonium.
Book
Introduction to soil microbiology
TL;DR: In this paper, the biological processes that take place in the soil and their importance to soil fertility, plant growth, and environmental quality are investigated from both descriptive and functional viewpoints, including microbial ecology, the carbon and nitrogen cycles, mineral transformation, and ecological interrelationships.

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.
Book
Microbial and Enzymatic Degradation of Wood and Wood Components
TL;DR: The oil crisis during the 1970s turned interest towards the utilization of renewable resources and towards lignocellulosics in particular, and the commercial utilization of this technology has not progressed as rapidly as one would have desired.
Journal ArticleDOI
The effect of added nitrogen on the rate of decomposition of organic matter
TL;DR: N added to decomposing organic matter often has no effect or a negative effect on microbial activity, at least in the long term, and this statement is supported by more than 60 papers cited.
