The main source of soil data in Bosnia and Herzegovina is the Basic Pedological Map at a scale of 1:50,000. The project to develop the Basic Pedological Map began in 1964 and was implemented by the Agropedological Institute Sarajevo. The Basic Pedological Map was developed on pedogenetic principles. The territory of BiH is covered by 71 sheets, all of which are within BiH, and another 45 sheets, which included areas of bordering countries. The methodology for soil research was agreed upon in 1964, and the completion of all sheets was completed in 1984. The profile density was approximately 1/100 ha, and analytical laboratory data for the profiles (physical and chemical properties) were included as an annex to each sheet. Soil classification is based on genetic-evolutionary principles, in which the soil type was the basic unit of the classification system. Mapping units included information on soil type, subtype, variety, and even soil formation. Morphological and lithological characteristics were the main criteria for differentiation. 1,176 mapping units have been identified on the soil map of BiH at a scale of 1:50,000.
