Soil buffering ability is one of the most important soil chemical characteristics influencing soil ecological function. It is the soil ability to resist acids or bases entering the soil environment and maintain pH within optimum values. We followed buffering ability in two different soil types - Gleysol (GL) and Fluvisol (FL). Further we determined soil reaction (pH/H0O, pH/KCl), total carbon content (Cox), and humic substances quality given by absorbance in UV-VIS spectral range and colour indexes (Q4/6). The aim of presented topic was to assess buffering ability and consider significant correlations with others chemical properties such as humus quality, soil reaction etc. Results showed considerable diversity in buffering ability in studied soils. Fluvisols showed higher buffering ability to acids while Gleysols showed higher buffering ability to bases.
