Temperature sensitivity of soil carbon decomposition [PDF]

open access: yes, 2013
The world's soils contain three times as much carbon as the atmosphere. Thus, any changes in this carbon pool may affect atmospheric CO₂ levels with implications for climate change.

Exploring variations in potential carbon and nitrogen mineralization in managed grasslands among the diversity of soils in North Carolina

open access: yesGrassland Research, EarlyView.
Under steady–state conditions, potential nitrogen mineralization in soil under grasslands is closely tied to potential carbon mineralization. This study provides supporting evidence that field–specific nitrogen fertilizer recommendations could be indicated by using a simple and rapid analysis of soil–test biological activity.

Plant litter decomposition is regulated by its phosphorus content in the short term and soil enzymes in the long term

open access: yesGeoderma
Plant litter decomposition plays a vital role in soil carbon (C) cycling and nutrient release, significantly influencing agricultural resource utilization and soil fertility management.

Post-thaw variability in litter decomposition best explained by microtopography at an ice-rich permafrost peatland

open access: yesArctic, Antarctic, and Alpine Research, 2018
Litter decomposition, a key process by which recently fixed carbon is lost from ecosystems, is a function of environmental conditions and plant community characteristics.

Drivers of litter mass loss and faunal composition of detritus patches change over time

open access: yesEcology and Evolution, 2021
Decomposition of vegetal detritus is one of the most fundamental ecosystem processes. In complex landscapes, the fate of litter of terrestrial plants may depend on whether it ends up decomposing in terrestrial or aquatic conditions.

Effects of Biochar and Maize Roots on CO2 Emissions and Microbial Biomass C in Loess Soils

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Refractory substances such as biochar and labile substances such as dead fine and coarse roots play important roles in soil organic matter dynamics and have key ecological functions. However, interactions between these substances have only rarely been studied.

Mass loss and nutrient dynamics during litter decomposition in response to warming and nitrogen addition in a desert steppe [PDF]

open access: yesFrontiers of Agricultural Science and Engineering, 2018
Plant litter decomposition has been studied extensively in the context of both warming and increased atmospheric nitrogen deposition. However, the temporal patterns of mass loss and nutrient release in response to warming and nitrogen addition remain ...

Looking at Soil as It Is: Evolution of Microscopic Soil Characterization From Kubiëna to Artificial Intelligence

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
We provide a historic overview of microscopic soil structure characterization from its founding father, Walter Kubiëna, to several technical revolutions like automation, digitalization, and artificial intelligence. In addition to technical advancements, we explore how concepts and research questions have evolved in time.

Early stage litter decomposition across biomes [PDF]

open access: yes, 2018
Through litter decomposition enormous amounts of carbon is emitted to the atmosphere. Numerous large-scale decomposition experiments have been conducted focusing on this fundamental soil process in order to under-stand the controls on the terrestrial ...

Leaf litter mixtures alter microbial community development: mechanisms for non-additive effects in litter decomposition. [PDF]

open access: yesPLoS ONE, 2013
To what extent microbial community composition can explain variability in ecosystem processes remains an open question in ecology. Microbial decomposer communities can change during litter decomposition due to biotic interactions and shifting substrate ...
