摘要：

Analysis of acid components in soil-KCl suspension filtrates from the mineral horizons was performed on the basis of analytical data reported between 1958 and 2003, including the data on more than 60 soil profiles (about 300 horizons) from the taiga zone of the Komi Republic. It was shown that the acid ions Al3+, H+ (exchangeable hydrogen), and Fe3+ and the basic ion H3SiO4− are the main components determining the pH of filtrates. Groups of horizons with the predominance of specific ions were separated.
