SOIL PROPERTIES OF CHROMIC LUVISOLS FROM KREMIKOVTSI AREA IN SOFIA MUNICIPALITY
Abstract
The result of the survey carried out on the territory of the Sofia-city municipality is presented, in relation to the application of the Program for the protection, sustainable use and restoration of soils as a limited and non-renewable natural resource. The obtained data on the Chomic Luvisols nearby the area of Kremikovtsi debate the basic physical and chemical soil characteristics. The priority task on the soil protection in the region aimed at the sustainable development, restoration and improvement of the soil resource. To fulfill this aim, samples from soil profile and additional sites from arable land were analyzed for texture, content and composition of organic matter, cation exchange capacity, soil bulk and soil particle density, soil moisture content at field sampling, porosity. The intrinsic peculiarity of organic substances is identified and the specific relationship within different fractions of extractable organic carbon. Humic acids are low molecular and with predominance of aliphatic over aromatic moieties in their molecules. The soil is affected by initial acidification but no evidence of destructive process of the soil adsorption complex, as the latter is characterized by high degree of saturation with bases. Chromic Luvisols are less vulnerable to erosion because, despite the low organic matter content, the colloidal clay content is significant.
