Abstract

The article is dedicated to the blessed memory of the outstanding scientist, teacher-mentor, professor, and doctor of biological sciences Tat’yana Alekseevna Sokolova. The scientific community knows and will always remember Tat’yana Alekseevna as an authoritative specialist in the field of soil science and mineralogy. The scope of her interests in the scientific and educational system is wide and diverse. One of the fundamental areas of her works is problems of soil acidity. The presented material contains some components of the creative heritage of Sokolova in the context of current research and prospects for its development. In particular, attention is drawn to the nature of the acidity of highly acidic soils (pHKCl <3.3 and \({\text{p}}{{{\text{H}}}_{{{{{\text{H}}}_{2}}{\text{O}}}}}\) <4.4). The specificity of the formation of the acid–base state of these objects is shown based on the example of soils of different origins. Causes of the low accuracy and reproducibility of the results of measuring the exchangeable acidity of highly acidic soils are revealed. Recommendations for improving the quality of measurements are given.
