Inventering av skogssador med flygbildsteknik som komplement till riksskogstaxeringens skogsskade inventering (Evaluation des dommages causés à la forêt à l'aide des photographies aériennes utilisées comme complément du recensement forestier

Soil organic matter (SOM) was monitored at 5 sites along a climatic transect extending from the Judean Mountains to the Dead Sea. The A. aims at analyzing the typical characteristics of SOM in different climatic regions, and analyzing deviations

The main aim of this study was to investigate temporal variations in SOM content in Tibetan soils as an important indicator of climate change. SOM content data were obtained from soil surveys conducted in the 1980s and resampled in the 2000s
. In this study, SOM content data from the A horizon of the soil profile were compared over time, and a paired t-test was conducted to verify differences between the 2 datasets. To determine the causes of SOM content decreases in the A horizon, soil samples were

This paper presents that the mean age of phytoliths and soil organic matter (SOM) in the uppermost 2.6 m of a latosol in central southern Brazil increases with depth in a regular, quantifiable fashion. The mean age of particles at each level results
from a balance between continuous translocation and selective dissolution. The AA. then examine the reliability of paleovegetation records inferred from soil phytolith assemblages and SOM carbon-isotope analysis by comparison with pollen and charcoal

The AA. investigate the quantitative and qualitative aspects of soil organic matter (SOM) losses caused by water erosion within a small catchment in Northern Laos, under steep slopes and slash and burn agriculture. The aim was to quantify
the erosion of black carbon and to identify the processes involved. The preferential erosion of black carbon compared to other SOM types can be explained by its light nature, absence of mineral interactions right after its formation and its resistance
