Challenges in modelling dissolved organic matter dynamics in agricultural soil using DAISY [PDF]

, 2008
Because dissolved organic matter (DOM) plays an important role is terrestrial C-,N-and P-balances and transport of these three components to aquatic environments, there is a need to include it in models.

Organic carbon transport and C/N ratio variations in a large tropical river: Godavari as a case study, India [PDF]

, 2005
This study gives an insight into the source of organic carbon and nitrogen in the Godavari river and its tributaries, the yield of organic carbon from the catchment, seasonal variability in their concentration and the ultimate flux of organic and ...

Carbon storage and DNA absorption in allophanic soils and paleosols [PDF]

, 2014
Andisols and andic paleosols dominated by the nanocrystalline mineral allophane sequester large amounts of carbon (C), attributable mainly to its chemical bonding with charged hydroxyl groups on the surface of allophane together with its physical ...

Changes in Particulate and Mineral Associated Organic Carbon with Land Use in Contrasting Soils [PDF]

Pedosphere, 2019
Abstract. Soil organic carbon (OC) is the largest terrestrial C stock and soils' capacity to preserve OC varies with many factors including land use, soil type and depth. We investigated the effect of land use change on particulate organic matter (POM) and mineral-associated organic matter (MOM) in soils.

Enrichment of Lignin-Derived Carbon in Mineral-Associated Soil Organic Matter

Environmental Science & Technology, 2019
A modern paradigm of soil organic matter proposes that persistent carbon (C) derives primarily from microbial residues interacting with minerals, challenging older ideas that lignin moieties contribute to soil C because of inherent recalcitrance.

Biodegradability of dissolved organic carbon in permafrost soils and aquatic systems: A meta-analysis [PDF]

, 2015
As Arctic regions warm and frozen soils thaw, the large organic carbon pool stored in permafrost becomes increasingly vulnerable to decomposition or transport.

Iron oxides, enzymes, and nutrients control soil organic matter stability in subtropical forest ecosystems

Geoderma
Although mineral protection plays a pivotal role in maintaining the long-term stability of soil organic matter (SOM), the mechanisms by which mineral protection acts through interactions with nutrients and enzymes remain unclear.

Warming mineralises young and old soil carbon equally [PDF]

, 2006
The temperature sensitivity of soil organic carbon decomposition is critical for predicting future climate change because soils store 2-3 times the amount of atmospheric carbon.

Long-term organic manure substitution enhances soil carbon stability via organically complexed iron oxides: Evidence from a 12-year field experiment

Geoderma
Organic amendments regulate soil organic carbon (SOC) and mineral-associated organic carbon (MAOC) stability by altering iron oxides. However, most sequential extraction studies for iron oxides have focused on bulk soil instead of mineral-associated ...

A New Approach Using Modeling to Interpret Measured Changes in Soil Organic Carbon in Forests; The Case of a 200 Year Pine Chronosequence on a Podzolic Soil in Scotland

Frontiers in Environmental Science, 2020
Scotland is continuing to afforest land in order to combat climate change, but the long-term capacity for carbon sequestration in forest soils is still uncertain.
