This paper reports the results of an interaction study designed to assess the effect of incorporating two of the most common organicmaterials in Borno state at different levels on raindrop detachment of three different soil types.

The aim of this paper is to demonstrate the sedimentology of the Harrinkangas formation and the origin of the enclosed organic remains. This esker contains peat layers and is covered by thin silty till. The AA. argue that it is possible to explain
this stratigraphy as a result of redeposition of organic matter through subglacial processes during the last glaciation.
Organische Spurenstoffe im Rheinwasser. in Arbeitstagung 1981 der Internationale Arbeitsgemeinschaft der Wasserwerke im Rheineinzugsgebiet (IAWR).. (Organic trace materials in the water of the River Rhine)
In this lecture detailed attention has been paid to the occurrence of organic matter in the Rhine. Several kinds of organic matter have been distinguished. Organic micropollution is described. (H. Winteraeken).
On the basis of exploratory soil surveys and joint field work by Dutch and Vietnamese soil scientists during February 1984 and September 1985, the different kinds of sulfidic materials in the western Mekong delta are described and their distribution
is presented in the form of a generalized map. Two main kinds of sulfidic materials have been recognized.

The paper presents the preliminary results of geomorphological and sedimentological investigations in the Ncamasere Valley, a seasonally back-flooded tributary of the Okavango River. Studies of organic horizons within cores indicate the differences
Seasonal changes in iron transport and nature of dissolved organic matter in a humic river in northern Finland
Finland ; Geochemistry ; Hydrology ; Iron ; Organicmaterials ; Seasonal variation ; Streams ; Water quality
Changes in the concentration of iron and dissolved organic matter (DOM), and in the colour and fluorescence properties in the River Küminkijoki were investigated as functions of the seasonal flow regime over a two-year period. Discussion
Kisérlet a tarsadalom térbeliségének torténelmi materialista értelmezésére. (Experiment at the interpretation of the spatial organization of society from the aspect of historical materialism)
This short paper is based in part on the information available on the actual functioning and composition of the soil community. The soil biota activity, which utilizes the organic matter for biosynthesis and maintenance at different levels
of organization, has a considerable effect on arid regions. This activity is stongly affected by abiotic factors which are highly unstable especially in a desert ecosystem.
The spatial distribution patterns of total organic carbon and total nitrogen show significant correlations with currents of the East China Sea Shelf. The purposes of this paper are to analyze characteristics of stable carbon and nitrogen isotopes
in seabed sediments, and discuss their implications for tracing organic matter source; and calculate contributions of different organic matter sources in seabed sediments.
Trace metals, organics and nutrients that are adsorbed onto suspended particles affect the supply of these materials to phytoplankton and zooplankton. Fecal pellets are important in fjords, an aqueous environment that is dominated by the vertical
flux of suspended sediments. Pelletization also allows the transport of undigested food to greater depths providing an important source of organicmaterial to benthic sediments and food to deep-water organisms.
Discussion of the results of the investigations of organic matter in the SW Atlantic, in the Polar Frontal Zone. The present goal was organic matter distribution at the period of its accumulation and bacterioplankton activization anomalously warm

Radiocarbon ages of soil organic matter are evaluated with a model which incorporates the dynamics of the C 14 content of soil organic matter. Discussion of the results and implications for the true ages of soils.
High-resolution paleoprecipitation reconstructions for the last glaciation based on the isotopic record organic matter in loess from Nussloch (Rhine Valley, Germany) are consistent with paleoprecipitation inferred from peat in the same area using
an independant method. Thus, δC 13 of loess organic matter can be used as a proxy for paleoprecipitation.

This paper uses measured data and the technique of geographical information system to calculate the terrestrial soil organic carbon reservoir, tries to analyze the spatial distribution characteristics of soil carbon reservoir and discusses the role
of soil organic carbon reservoir on the global change.
Erodibility of soil and organic matter : independence of organic matter resistance to interrill erosion

In this paper, initial results from a series of interrill erosion experiments conducted on the enrichment of organic matter are reported. Two intensely farmed silts from Devon, UK, and the Eifel region, Germany, were subjected to artificial rainfall
. The texture of the two soils is almost identical, while organic matter content and aggregate stability, and thus aggregate breakdown and interrill erosion differ significantly. The design of the rainfall simulation experiments aimed at measuring organic matter
