    Abstract : A secondary and a pioneer tree species can with advantage be included in a mixed stand to increase the use of sunlight. Nitrogen-fixing plants have been shown to increase the supply of nitrogen in the soil by, for example, litter fall. This deposition acts as a biological fertilization, which may be used by non-fixing plants. READ MORE

  4. 3. Accumulation of carbon and nitrogen in Swedish forest soils over stand age

    University essay from SLU/Dept. of Soil and Environment

    Author : Petros Georgiadis; [2011]
    Keywords : Soil Organic Carbon; Nitrogen; Decomposition; Stand age; Litter-fall;

    Abstract : Forest disturbance and harvesting regimes may affect the carbon (C)amounts stored in forest soils. The amount of soil C decreases after harvest and recovers gradually. Earlier chronosequence studies have suggested 50% decrease of the forest floor within the first 15 years after harvest. READ MORE
