consequently decreased with stand age. Higher SOC levels were in the mature stand. In the mineral topsoil layers, total SOC and total nitrogen were in the upper 10-cm layer in the 30-year-old stand. A post-harvest peak in mineral N concentration was observed and other nutrients, especially mobile P 2 O 5 , K 2 O, Ca 2+ and Mg 2+ , increased the clear-cuttings and in the 10-year-old stand compared to the mature stand.
