The change in land use is one of the factors responsible for ecosystem equilibrium disturbance and it might cause the undesirable processes leading to the decrease of soil quality. Agricultural land afforestation becomes more and more popular and therefore the possible changes of soil physical and chemical properties are topical. The experiment was carried out in 2010, when two adjacent fields – one still under agriculture, another with 15 years old planted Scots pine (Pinus silvestris L.) stand were investigated. Soil (Cutanic Albeluvisol) profile description in each location, as well as soil augering was done. The soil samples were tested for some physical and chemical properties. The results showed that under pine stands, compared with agricultural land, the soil bulk density was decreased, but the total porosity and relative waterholding capacity increased. Soil acidification, increase of organic matter and changes in C:N ratio were observed in humus accumulation horizon under the pine stand. Phosphorous and potassium content in soil, available for plants, was higher under the pine plantation.
