The aim of this work is based on data from large-scale soil survey, and on our own research to try to systematize and evaluate the main and economically significant factors for degradation of the complex of Cinnamon forest soils (Chromic luvisols) located near the town of Svilengrad, southeast Bulgaria. On the basis of data from large-scale soil survey, which is mainly based on genetic method for soil taxonomy is made generalization of soil map data, as are kept the requirements for conformity of soil types according to classification of FAO and the International soil database. Separate soil units are evaluated about: the degree of development of soil erosion, particle size distribution, degree of dehumification and soil acidity to a level harmful for the main agricultural crops. In the discussed in this study, complex of Cinnamon forest soils, was found that the differentiation of soil types on the basis of an improved system for taxonomy and classification, used in the FAO classification, better reflects the extent and direction of the degradation process. This is achieved without explicit mention of any of the degradation processes in the name of the soil units.
