A detailed analysis on the distribution of parent rocks in Bulgaria, their genetic and post genetic interrelation and their specific influence on soil processes and soil formation has been carried out. We reviewed the main rock types igneous, volcanic, sedimentary and metamorphic and their relation with the varieties of geochemical differentiated landscapes. A critical approach in the examination of the influence of different geochemical anomalies, barriers and pools has been used. The red soils in Bulgaria have been characterised as a unique geological phenomenon. It has been estimated that the huge soil-geological variety is a basis for agroecosystems formation and the differentiation of the 50 agroecological regions in the country. On this basis a new definition of the scientific discipline Agroecology has been proposed.
