Buffering functions of virgin and cultivated soils in the East European Russian taiga

We studied virgin and cultivated Albeluvisols developed in the loess-like silty loam in the middle taiga of the East European Russia. Tillable layer has considerable reserves of buffering components which significantly exceed total stock of buffering components in forming it litter and eluvial horizons of virgin soil. This fact can be regarded as one of positive effect the mechanisms on soil ecological functions and cover. The method of pK-spectroscopy is used to study acid-base properties of parent materials. Key words: buffering capacity, continuous potentiometric titration, pK-spectroscop
