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,

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 ...

The role of sideration in the accumulation of organic matter

АгроЭкоИнфо, 2021
Data on the effect of long-term (18 years) use of crop sideration (white mustard), both separately and in combination with straw fertilizer, on the content of organic matter in sod-podzolic soil and crop productivity are presented. In the conditions of an acute shortage of organic fertilizers in agriculture in the central regions of the non-Chernozem ...
