The article deals with the Luvisols soil type, which is spread in all areas in Bulgaria. It is very important for national agriculture and forestry. This soil type occupies vast areas in the hilly and low-mountainous territories of the southern parts of Danubian plain, the Fore-Balkan area and southern Bulgaria. They are distributed mainly in agricultural areas and almost all-important agricultural crops could grow on them. In the past Luvisols were spread in the area of oak forests, today these soils are cultivated. This leads to loss of soil organic matter, deterioration of the water-physical regime and physicochemical properties. Descriptive statistics and correlation analyses ware used to analyze the differences in soil parameters. The results show that, surface horizons have a weak structure and the aggregates are not stabled. The carbonates are washed in depth. The reaction is from slightly acidic to moderately acidic (pH 4.3 - 6.8). Exchange acidity is not high 0 - 2 cmol c .kg −1 . The textural composition of studied soils is mostly sandy-loamy to clay and clay-loamy.
