Aerobic and anaerobic decomposition of organic matter in marine sediment: Which is fastest?

Limnology and Oceanography, 1995
The enigma of aerobic vs. anaerobic decomposition in marine sediments was addressed by means of a thin‐layer incubation technique. Two different 14C‐labeled plant materials, aged diatoms (Skeletonema costatum) and fresh barley hay, were each mixed into intertidal sediment and spread in a 1.5‐mm layer on the bottom of oxic and anoxic chambers.

Effect of alternate aerobic and anaerobic conditions on redox potential, organic matter decomposition and nitrogen loss in a flooded soil

Soil Biology and Biochemistry, 1975
Abstract The effect of several cycles of varying length of alternate aerobic and anaerobic conditions on redox potential, organic matter decomposition and loss of added and native nitrogen was investigated under laboratory conditions in flooded soil incubated for 128 days.

The effects of salinization on aerobic and anaerobic decomposition and mineralization in peat meadows: The roles of peat type and land use

Journal of Environmental Management, 2014
Peat soils comprise a large part of the western and northern Netherlands. Drainage for agriculture has caused increased soil aeration which has stimulated decomposition and, hence, soil subsidence, currently amounting to 1-2 cm/yr. River water is supplied to these peat areas in summer to prevent drying out of the peat soils.

Decomposition of Thiourea Dioxide under Aerobic and Anaerobic Conditions in an Aqueous Alkaline Solution

Russian Journal of Physical Chemistry A, 2020
The kinetics and mechanism of the decomposition of thiourea dioxide in an aqueous alkaline solution under aerobic and anaerobic conditions are established. It is discovered that along with the decomposition of thiourea dioxide molecules with C–S bond cleavage and the subsequent formation of sulfoxyl acid anions, there is a reversible stage of the ...

Influence of zinc on aerobic and anaerobic decomposition of organic matter

Zeitschrift für Pflanzenernährung und Bodenkunde, 1980
AbstractIncreasing amounts of Zn were added to organic manure materials in order to establish its permissible maximum concentrations depending on the decomposition process and Zn‐source. The mixtures were allowed to decompose aerobically for 46 days and anaerobically for 52 days, respectively. Zn‐concentrations up to 2 000 ppm as ZnSO4 and ZnO or 50 mg/

ENDRIN DECOMPOSITION IN SOILS AS INFLUENCED BY AEROBIC AND ANAEROBIC CONDITIONS

Soil Science, 1977
ABSTRACT The relative persistence of endrin in soils as related to flooding and alternate “anaerobic” (flooded unstirred) and “aerobic” (flooded stirred) conditions was studied in three soils by radiotracer technique. More rapid degradation of endrin occurred in all three soils under flooded conditions than under nonflooded conditions. Autoradiography

Neural image analysis for estimating aerobic and anaerobic decomposition of organic matter based on the example of straw decomposition

SPIE Proceedings, 2012
The purpose of the project was to identify the degree of organic matter decomposition by means of a neural model based on graphical information derived from image analysis. Empirical data (photographs of compost content at various stages of maturation) were used to generate an optimal neural classifier (Boniecki et al. 2009, Nowakowski et al.

A comparative study of anaerobic and aerobic decomposition of quercetin glucosides and sugars in onion at an ambient temperature

Frontiers in Life Science, 2015
The purpose of the study was to investigate the decomposition of onions under anaerobic and aerobic conditions. The main aim was to determine the changes in composition of quercetin-related compounds and sugars, with simultaneous analysis of total phenolics, total flavonoids and antioxidant activity.

Chemistry of metal oxo alkyl complexes. Mechanistic studies on the anaerobic and aerobic decompositions of molybdenum(VI) dioxo dialkyl complexes

Organometallics, 1991
The anaerobic and aerobic decompositions of L{sub 2}Mo(O){sub 2}R{sub 2} (L{sub 2} = 4,4{prime}-dimethyl-2,2{prime}-dipyridyl, R = CH{sub 2}Ph, 1; R = CH{sub 2}C{sub 6}H{sub 4}CH{sub 3}-p, 2; R = (CH{sub 2}){sub 4}CH:CH{sub 2}, 3; R = CH{sub 2}CHMe{sub 2}, 4; R = CH{sub 2}CMe{sub 3}, 5; R = CH{sub 2}CMe{sub 2}Ph, 6) were studied.

The contribution of aerobic and anaerobic decomposition processes to greenhouse gas emissions of peatland dairy meadows.

Peatlands cause ~2% of anthropogenic greenhouse gas (GHG) emissions due to drainage. In study, we aimed to assess (1) if laboratory aerobic and anaerobic heterotrophic respiration rates of peat layers accurately represent observed CO2 and CH4 (chamber and eddy-covariance respectively) emissions, and to assess (2) the contribution of aerobic and ...
