Rositza Mikova

Abstract: A description of the soil and climatic conditions in Bulgaria and the suitability of agricul-tural lands for growing wheat and sunflower is made. The territorial distribution of the agro-ecological potential of the agricultural lands in 50 agro-ecological regions is used, grouped in seven by characteristic groups, which bear the names of the main soil types: chernozems; gray-brown forest soils; gray-brown pseudo-podzolic forest soils; resins and cinnamon forest soils; brown forest soils and mountain-meadow soils. Based on the assessments of the quality from the agro-ecological regions, quality cards have been created for the suitability of the agricultural
lands in Bulgaria for growing wheat and sunflower. An analysis of the state and trends in the change in the final production, area, average yield, production of the studied agricultural culture in Bulgaria for the period 2007-2017 is made.
