Magnesium content in organic layer.
The pH in the organic layer also explains most of the variation in species numbers.
C/N ratio in the organic layer.
The influence of vegetation on chemical soil characteristics is most apparent in the organic layer.
The magnesium contents of the organic layer reflect this relation.
Frequency distribution of pH values in the organic layer.
For about 40% of the plots concentrations in the organic layer vary between 10 and 14 g N per kg figure 10.
Figure 12 shows the lead concentration in the organic layer.
Significant differences in organic layer pH could be detected between all paired groups except beech-oak and pine-spruce.
Lead concentrations in the organic layer.
This evaluation was confined to nitrogen in the organic layer since this pool is most liable to change due to nitrogen deposition.
Nitrogen concentrations in the organic layer.
In reality, however, not all N will be retained in the organic layer since part is accumulating in the mineral soil and part is leached to groundwater.
This exceedance is found mostly in regions with low C/N values in the organic layer.
The leaching andretention of N were mainly determined by N deposition, the organic layer carbon-nitrogen ratio(C/N ratio), and the annual temperature.
Nitrogen leaches from forest soil at a carbon to nitrogen ratio below 23 in the organic layer.
The amount of Pb in the organic layer was 41 mg per kg, in the mineral subsurface layer 32 mg per kg, and in the subsurface layer 24 mg per kg.
For Pb the E-horizon was at risk, while the organic layer appeared safe.
O: organic layer(consisting of litter and humus); M1: mineral surface layer(0-5 or 0-10 cm layer); M2: mineral subsurface layer 10-20 or 10-30 cm layer. .
Criteria used for the assessment of heavy metal concentrations in the organic layer are given in table 4.
Unusually high nitrogen contents in the organic layer, indicated by a lower ratio in this layer than in the underlying mineral layer, were observed in 17% of the plots.
It is transparent to visible light and has a high work function which promotes injection of holes into the HOMO level of the organic layer.
Distribution(% of observations)over the classes'low','elevated and'high' of the heavy metal contents in the organic layer of stands within the ICP Forests level II monitoring programme.
Within area 2, defoliation of Scots pineincreases with altitude and decreases with the weight of the organic layer.
Moreover, the C/N ratios in the organic layer of soils are often unusually low in these same regions(see chapter III), and high in regions where low N concentrations in needles were found.
The investigation of the nitrogen pools shows that the median N pool(50th percentile) in the organic layer is 396 kg/ha see table 1.
The extraction of high-cost products from an aqueous layer to an organic layer(or vice versa), or salting-in/salting-out processes, are very common and important procedures in the chemical industry.
Up to now, studies within the context of the ICP Forests level II monitoring programme have been limited to a comparison of measured metal concentrations in forest soils to critical limits,focusing on the organic layer.
Estimates of C and N sequestration rates in the forest soil organic layer were also calculated for specific sites based on the"limit value" concept that uses data on organic matter decomposition.
In conifer stands the 0-10cm layer of the mineral soil was similarly acidic, whereas in beech and oak stands the surface mineral layer was more acidic(60%<pH 4.2) than the organic layer.
