Up-to-date and accurate information on soil properties is important for precision farming and environmental management. The spatial information of soil properties allows adjustments of fertilizer appl...
Constrained microbial processing of allochthonous organic carbon in boreal lake sediments
boreal lake sediments Constrained microbial processing
2014/4/4
We investigated sediment bacterial metabolism in eight lakes with different inputs of allochthonous and
autochthonous organic carbon in south-central Sweden. Sediment bacterial production, mineraliza...
The Paths of the Suspended Particulate Inorganic and Organic Matter in a Small Urban Estuary:The Aarhus Harbour Estuary
Inorganic and Organic Matter Urban Estuary Aarhus Harbour Estuary
2009/10/27
The nverine supply of suspended inorganic and organic sediment, its temporal
and spatial distribution and its exchange with the bay, were estimated for an
urban estuary (Aarhus Harbour Estuary, Denm...
Transport and Chemodynamics of Organic Micropollutants and Ions during Snowmelt
Transport Chemodynamics Organic Micropollutants Ions
2009/10/27
By means of laboratory experiments and field measurements we investigated
the chemodynamics and transport behaviour of organic micropollutants and
inorganic ions in melting snowpacks. Dissolved subs...
Optical Properties of Dissolved Organic Matter in Finnish and Estonian Lakes
Optical Properties Dissolved Organic Matter Finnish and Estonian Lakes
2009/10/22
The main objective of the present study is to test various methods for describing
the absorption spectra of coloured dissolved organic matter (CDOM) and to
determine the numerical values of some opt...
Landscape scale patterns in the character of natural organic matter in a Swedish boreal stream network
Landscape scale patterns natural organic matter stream network
2009/9/11
This paper defines landscape-scale patterns in the character of natural organic matter (NOM) and tests for relationships to catchment soil, vegetation and topography. The drainage network of a boreal ...
Assessing the biodegradability of terrestrially-derived organic matter in Scottish sea loch sediments

Lignin oxidation products, oxygen uptake rates, molar organic carbon to nitrogen (OC/N) ratio (from bulk elemental analysis) and Rp values (from loss on ignition experiments, the ratio of the refracto...
Fluvial organic carbon flux from an eroding peatland catchment, southern Pennines, UK
dissolved organic carbon particulate organic carbon organic carbon
2009/4/29
This study investigates for the first time the relative importance of dissolved organic carbon (DOC) and particulate organic carbon (POC) in the fluvial carbon flux from an actively eroding peatland c...
Modelling the effects of climate on long-term patterns of dissolved organic carbon concentrations in the surface waters of a boreal catchment
Dissolved organic carbon artificial neural networks
2009/4/29
Dissolved organic carbon concentrations ([DOC]) in surface waters are increasing in many regions of Europe and North America. These increases are likely driven by a combination of changing climate, r...
Effect of porous photocatalyst reactor on decomposition of organic matter and nitrification of ammonia in sewage

2009/4/2
A system for sewage water treatment in a primary sedimentation pond was investigated using a reactor tank equipped with cylindrical reactors which had porous photocatalyst coated with TiO2 around an u...
Features and sources of organic components in surface sediments of Lake Nishi-inbanuma in Chiba Prefecture, Japan
eutrophic lake Lake Nishi-inbanuma organic constituents surface sediment
2009/4/2
Lake Nishi-Inbanuma (area 680 ha, average depth 1.8 m) in northwest Chiba Prefecture, Japan, is known as a typical eutrophic lake. We studied organic components in the surface sediments (0-5 cm) of th...
