With aim of usage of glauconites as a K-fertilizers and microfertilizers the sorption properties of modified glauconite with respect to ions  of Zn, Mn, Ni, Cu, Co (II), containing in  insufficient quantity in  most soils of  Republic of Kazakhstan were studied.

The phase composition of glauconite changes at the thermal modification and the sorption properties decrease. It was found that mechanochemical modification with the addition of NaH2PO4 has the maximum effect of sorption (αsorb. = 94.9%) because of the transition of the Ca – form of  glauconite to  the Na-form.
