Soils
The paper deals with soil properties characterized the intrinsic peculiarity of studied Chromic Cambisols from the Upper Thracian Lowland, in the Southern Bulgaria. To fulfill the aim, a systematic survey and sampling have been carried out on the terrain with conventional and organic systems of farming. Soil physical, chemical and physicochemical properties were discussed including the analyzed data for particle size distribution, content and composition of organic substances, cation exchange capacity, soil bulk density, soil particle density and porosity. The organic matter was directly dependent on the local environmental conditions, the result of natural bioactivity. Soil adsorbent was affected by acidification in the surface horizon so there was evidence of initial destructive processes of the soil adsorption complex, despite the relatively high degree of soil saturation with bases. The comparison between conventional and organic farming showed that there was no statistically significant difference in the studied soil indexes, that could be provoked by the farming system applied at the trials.
