The paper presents the physical and chemical properties of brown soil on limestone, as well as dystric brown soil on silicate substrates. Research was conducted in the western part of the Republic of Srpska, on the territory of the forest management area "Mrkonjićko" in three forest management units and four compartments. The aim of the work is to analyze the properties of cambic soils in different ecological and vegetation conditions in the mentioned research area. Forests of beech, fir and spruce (Piceo-Abieti-Fagetum) are the most represented type of vegetation of the research object. A total of four basic pedological profiles were opened, and the laboratory analysis of the physical and chemical properties of the soil included a total of nine soil samples from the basic genetic horizons. For each analyzed type of soil, classification belonging to lower systematic levels was carried out. Brown soil on limestone has one subtype: typical. Dystric brown soil includes two subtypes: typical and ilimerized. The physical properties of the investigated soils are generally favorable for the growth and development of vegetation, while the chemical properties indicate limited trophicity of both types of soil. The production potential of brown soil on limestone and acidic brown soil in the study area can be characterized as moderate.
