Does the Slope Aspect Influence the Soil Organic Matter Concentration in Forest Soils?

Forest soils belong to the major carbon sinks on Earth because of their high organic matter content. from Europe store approximately 1.5 times more than trees (EC/UN-ECE 2003). As dystric cambisol (2,292,385 ha) and eutric (869,909 are most widespread forest in Romania, we studied 5958 pedogenetic horizons 6784 horizons. A series correlations was made between soil elevation, but also with tree age stand production class. The differences stratified terms slope aspect categories were tested, multiple linear regression used determine influences some relief (elevation) (age) characteristics Overall, content increased increasing elevation. Based all 12,742 samples over a period 33 years, is influenced by elevation age, especially shaded partially aspects.
