Organic matter accumulation in submerged soils [PDF]
, 2003 Abstract The decomposition and accumulation of organic materials in submerged (anaerobic) soils and sediments differ considerably from those in their aerobic counterparts. This is caused by the lack of oxygen or anaerobiosis. Compared to aerobic soils, there is preferential accumulation of organic matter in submerged rice soils.

Natural organic matter coagulation [PDF]
, 2005 The removal of natural organic matter (NOM) is one of the main challenges facing water utilities in both the UK and the US. As a consequence of changes in land management and an increased carbon loss from solids, a greater amount of accumulated ...

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.

New organic matter degradation proxies: Valid in lake systems? [PDF]
, 2004 We determined concentrations and diagenetic state of organic matter in two cores from Lake Zug, Switzerland. To obtain a general picture of organic matter decay in the lake, we measured bulk parameters such as total organic carbon, total nitrogen, and ...

The impact of sea-level rise on organic matter decay rates in Chesapeake Bay brackish tidal marshes [PDF]
Biogeosciences, 2013 The balance between organic matter production and decay determines how fast coastal wetlands accumulate soil organic matter. Despite the importance of soil organic matter accumulation rates in influencing marsh elevation and resistance to sea-level rise,

Survey on Organic Matter Accumulation in the Anzali Lagoon Sediments
Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 1997 Organic matter was determined in different parts of lagoon sediments during three years with annual average Of 137.32 ± 28.60 milligram in one gram dried sediment.

Synergy of Fresh and Accumulated Organic Matter to Bacterial Growth [PDF]
Microbial Ecology, 2008 The main goal of this research was to evaluate whether the mixture of fresh labile dissolved organic matter (DOM) and accumulated refractory DOM influences bacterial production, respiration, and growth efficiency (BGE) in aquatic ecosystems. Bacterial batch cultures were set up using DOM leached from aquatic macrophytes as the fresh DOM pool and DOM ...

Preferential degradation of leaf- vs. root-derived organic carbon in earthworm-affected soil [PDF]
, 2020 Earthworms are integral parts of many ecosystems and may play a decisive role in determining whether soils function as carbon (C) sink or source. However, information on how earthworms affect the composition and stability of soil organic matter (SOM) is ...

Simulated study on interactions between heavy metals and organic matter in contaminated soil
浙江大学学报. 农业与生命科学版, 2009 In order to understand the interactions between accumulation of organic matter and heavy metals in contaminated soil, an incubation experiment was conducted by adding different levels of organic materials, Pb and Cu to soil.
