- Аннотация: A zinc-containing material based on bentonite clay with a montmorillonite content of 95 wt %, modifi ed with a concentrated Na2SiO3 solution, was obtained, which can be used as a long-term microfertilizer. Zn2+ in an amount of 3 wt % is blocked in the interlayer space of montmorillonite by silica gel clusters, which signifi cantly slows down the degree of its leaching into the soil. During ten cycles of contact of the material with water in a slightly acidic medium, depending on its dispersity, 5–11% of the introduced amount of Zn2+ was released into the aqueous phase, which is 2–4 times less compared to the unmodifi ed sample.
