Zinc, copper and manganese are obtained by plants in ion form. Use of metal salts
as components of solvable microfertilizers is inefficient because salts, as well as complex
metal compounds, are easily washed out. We studied the possibility of prolonged support
of plants with microelements by introducing ions and complex microelement compounds
in soil in form of nanocomposite materials of the "host-guest" type.
Objectives. Our main objective was to obtain nanocomposite materials of "host-guest"
type based on the research of natural zeolites and complex ions of zinc, copper and
manganese, and to study their effect in real-world conditions in grain and vegetable crop
rotation rotation (results of the first stage (1 year) of the 3-year study are prsented.).
Methods. Natural zeolites were impregnated by complex ions of zink and copper
[Cu(NH 3 ) 4 ] 2 + and [Zn(NH 3 ) 4 ] 2 + in aqueous solution. Zeolite-manganese nanocomposite
was obtained using the aqueous solution of MnCl 2. Both zeolite portions were mixed and
introduced into soil. Field experiments were conducted on carrot and beetroot. We
compared our results with seeds treated with microfertilizers.
Results. Use of nanocomposite materials increases concentration of zink by 50% in carrot
(up to 3 mg/kg) and by 100% in beetroot (up to 4 mg/kg). Copper concentration in both of
these plants increases by 30% compared to control samples. Manganese concentration in
vegetables is not affected by change of technology. Processing of seeds with
microfertilizers has no influence on concentration of microelements in vegetables.
Conclusions. Use of nanocomposite materials allowed decreasing mobility of
microelements in soil which led to the increase of zinc and copper concentration in carrot
and beetroot.
