ABSTRACT The transformation of primary forestlands into lands under cultivation exerts an impact on the physical and chemical properties of the soils, leading to loss of carbon from the soil. The aims of this study were (1) to estimate the impact of different land use on organic carbon stock (OC-stock) and (2) to determine the clay percentage, the dispersion factor, and bulk density with regard to soil management. Thirty soil profiles were sampled as follows: four under primary forests with 80-100 years (old growth); two under secondary wood forests with 45-50 years; eight under secondary young forests with 15-25 years; four under pasture land with 15-20 years; and 12 under continuous cultivation for > 50 years. We determined the changes in OC-stock in...
