The work objective is to differentiate rural land of Slovakia with aspect to the possibility of effective spring barley growing. The differentiation is based on pedo-climatic and production economic parameters. At soil categorization, correlation relationships between the site properties (soil and climatic conditions) and crop biological and agro-technical requirements were considered. Spring barley requirements were included into yield databases using the software filters in the way that the given site property excluded or limited barley growing, what was reflected in predicted production. The prediction was subsequently interpolated into four suitability categories: soils not suitable for spring barley growing, less suitable soils, suitable soils and very suitable soils. The database was formed and each of the Bonited Pedo-Ecological Unit (BPEU) was added in it as well as particular category of suitability for barley growing. By mediation of the Geographic Information System on BPEU distribution in Slovakia, the map of categories of soil suitability for spring barley growing was also generated. In Slovakia, there is 20% of farmland very suitable for spring barley growing, 24% suitable, 24% less suitable and 32% non-suitable soils for spring barley growing according to our calculation. In the paper, these categories are characterized in details and specified from the view of geographic, soil, climatic, productivity, economic and energetic parameters.
