Abstract

Secondary saline alluvial soils formed under conditions of the taiga-forest zone within the Verkhnekamsk salt deposit have been studied. The results of this study indicate that continuous soil salinization is caused by mineralized water filtering from the stored waste products of potash production. The influence of surface and ground waters of chloride–sodium and potassium–sodium composition results in the formation of solonchakous soils and secondary solonchaks. The specific features of these soils—acidity neutralization, gypsum formation, the appearance of carbonates, the entering of sodium and potassium into the soil adsorption complex, and an increase in its base saturation—are described, and further technogenic evolution of alluvial soils is predicted. It is suggested that qualifiers Salictechnic, Chlordictechnic, Gypsictechnic, and Sodictechnic should be added to the system of the World Reference Base for Soil Resources for better characterization of the specific technogenic salinization of soils, which have preserved the main morphological features of the natural profile.

针叶林区小流域土壤中Solonchak过程的发展与钾盐的产生

摘要

已经研究了在Verkhnekamsk盐矿床内针叶林林带条件下形成的次生盐冲积土壤。这项研究的结果表明，土壤持续盐碱化是由从钾肥生产中储存的废物中过滤出的矿化水引起的。氯化物-钠和钾-钠组成的地表水和地下水的影响导致solonchkous土壤和次生slonchaks的形成。描述了这些土壤的特定特征-酸中和，石膏的形成，碳酸盐的出现，钠和钾进入土壤吸附复合物以及其基础饱和度的增加-并预测了冲积土壤的进一步技术演化。建议限定词为Salictechnic，Chlordictechnic，Gypsictechnic，世界土壤资源参考库，用于更好地表征土壤的特定技术盐渍化，这些盐渍化保留了自然剖面的主要形态特征。
