Processes of chemical weathering of new types of agromeliorants

Abstract

In studies in a model experiment, it was found that in the process of weathering saponite-containing basaltic tuffs, mainly cations K, Ca and Mg are washed out and some alkalinization of the solution occurs.
In the process of weathering of glauconite, both alkaline and alkaline earth cations K, Ca and Mg, and acid cations Al and Fe actively pass into the solution, which leads to acidification of the solution.
Differences in the weathering processes of saponite-containing basalt tuffs and glauconite should be taken into account when they are used as agromeliorants in biocenoses.
