摘要：The aim of this study was to investigate the effects of simulated acid load on soil organic carbon and plant biomass production. A short-term pot experiment with spring barley was conducted on 6 different soil types (Chernozem, Fluvisol, Eutric Cambisol, Stagnosol, Dystric Cambisol, Podzol). Two treatments were applied (A: watering with distilled water of pH 5.4; B: watering with acid solution of pH 2.5). Due to the acid watering, a pH decreased in all six soil types. Acid load enhanced aboveground dry matter biomass production at all six soil types. TOC stock increased in both treatments in all soil types with the exception of Eutric Cambisol. Results of humic-fulvic acid ratio showed that acid load caused deterioration of organic matter quality in four soil types and improvement in two soil types.
